What Exactly Are Blondies?

Before we dive into why these specific Oreo Blondies are a must-try, let’s clarify what a blondie is! Often mistaken for brownies, blondies are their delightful, vanilla-based cousin. While brownies get their rich, dark color and intense flavor from cocoa powder, blondies are made with a base of butter, brown sugar, and vanilla extract, giving them a golden hue and a distinctly buttery, caramel-like flavor profile. They typically boast a wonderfully chewy, dense, and moist texture, often featuring a slightly crisp top crust. Our Oreo Blondies take this classic treat to the next level by incorporating America’s favorite cookie, adding an irresistible crunch and iconic chocolate-creme flavor that makes them truly stand out.

Essential Grocery List for Your Oreo Blondies

Below, you’ll find a breakdown of the key ingredients needed for these delectable Oreo Blondies, focusing on items you might need to purchase. For a full, precise list of quantities and detailed instructions, please make sure to check out the comprehensive recipe card located further down the page!

• Butter: I specifically use unsalted butter for better control over the salt content. It’s crucial that the butter is melted and then allowed to cool slightly – warm is perfectly fine, but never hot, as hot butter can “cook” the eggs prematurely and affect the blondie’s texture. Butter provides the rich, foundational flavor and contributes significantly to the chewy texture.
• Light Brown Sugar: This ingredient is vital for achieving that signature chewy texture and depth of flavor in blondies. It adds not only sweetness but also moisture, and its molasses content helps create a more complex, caramel-like taste that perfectly complements the vanilla and Oreo.
• Granulated Sugar: While brown sugar gives chewiness, granulated sugar ensures a balanced sweetness and helps create that desirable slightly crisp, crackly top crust on your blondies, adding another layer of texture.
• Eggs: For optimal mixing and a smooth batter, ensure your eggs are at room temperature. They act as a binder, providing structure and richness, making the blondies tender and moist. The extra egg yolk adds richness and chewiness.
• Vanilla Extract: Pure vanilla extract is a non-negotiable for blondies! It significantly enhances all the other flavors, adding a warm, aromatic depth that is characteristic of a classic blondie. Don’t skimp on quality here!
• Cornstarch: This secret ingredient is key to achieving a wonderfully soft and tender crumb. It helps to slightly reduce gluten development in the flour, resulting in a melt-in-your-mouth blondie that isn’t tough.
• Baking Soda: As a leavening agent, baking soda reacts with acidic ingredients (like brown sugar) to help the blondies rise slightly, ensuring they aren’t overly dense and have a pleasant, light lift.
• Salt: A small amount of salt is crucial for balancing the sweetness and enhancing all the other flavors, preventing the blondies from tasting one-dimensional. It truly makes every ingredient pop.
• All-Purpose Flour: This forms the foundational structure of your blondies. It’s important to measure it correctly (spoon and level!) to ensure the perfect consistency and avoid a dry or tough result.
• Semisweet Chocolate Chips: These little gems melt into gooey pockets of chocolatey goodness, providing bursts of rich flavor and a delightful contrast to the buttery blondie base and crunchy Oreos.
• Oreo Cookies: The star of the show! Chopped Oreo cookies are folded into the batter, delivering a fantastic textural crunch and that beloved, distinctive chocolate-creme flavor that makes these blondies truly unique and irresistible.

Note: Beyond your ingredients, make sure to have an 8×8 baking pan and parchment paper on hand as well. These tools are essential for a smooth baking process and easy removal of your finished Oreo Blondies.

Expert Tips for Crafting the Perfect Blondie Batter

Achieving truly incredible Oreo Blondies starts with the batter. Follow these expert tips for a smooth, perfectly mixed base that will bake up beautifully. I personally use my reliable KitchenAid mixer, which I acquired from here, and the baking pan I used for this recipe.

• Use Room Temperature Ingredients for a Homogeneous Mix: This tip is crucial for many baking recipes, and especially for blondies. When ingredients like eggs are at room temperature, they emulsify much more easily with the melted butter and sugar, creating a smooth, cohesive batter. Cold eggs can cause the butter to seize up, leading to a lumpy texture. Simply take your eggs out of the fridge about 30 minutes to an hour before you plan to start baking.
• Measure Flour Accurately – Spoon and Level: Improperly measured flour is a common pitfall in baking. Scooping flour directly from the bag compacts it, resulting in too much flour and a dry, dense blondie. Instead, gently spoon the all-purpose flour into your measuring cup and then level it off with the straight edge of a knife. This ensures you get the precise amount needed for that perfect chewy texture.
• Chop Oreo Cookies into Distinct Chunks: While some recipes call for crushed cookies, we want noticeable pieces of Oreo throughout our blondies. Chopping the cookies into small, varied chunks, rather than fine crumbs, provides a delightful textural contrast. You’ll get distinct bursts of cookie crunch and flavor in every bite, adding to the overall appeal and giving these Oreo Blondies their signature character.
• Line the Baking Pan with Parchment Paper for Easy Removal: This simple step makes a world of difference. Lining your 8×8 baking pan with parchment paper, leaving an overhang on two sides, creates “handles” that allow you to easily lift the baked blondies out of the pan. Using metal binder clips to secure the parchment paper to the sides prevents it from shifting as you spread the batter. This ensures clean cuts and prevents sticking, making serving a breeze.
• Avoid Overmixing the Batter: Once you add the dry ingredients (flour, baking soda, cornstarch, and salt) to the wet mixture, it’s vital to mix gently and only until they are just combined. Overmixing develops the gluten in the flour, which can lead to tough, dense blondies instead of the desired chewy and tender texture. Use a rubber spatula and fold the ingredients together with a light hand, stopping as soon as no dry streaks remain.

Overall Baking Tips for Blondie Perfection

Beyond the batter, a few key considerations during the baking process will ensure your Oreo Blondies turn out flawlessly:

• Always Check for Doneness Carefully: Oven temperatures can vary significantly, so relying solely on the recipe’s baking time isn’t always foolproof. Keep a close eye on your blondies, especially towards the end of the baking time. They are typically ready when the edges are lightly golden brown, and a toothpick inserted into the center comes out with a few moist crumbs clinging to it – not wet batter, but definitely not completely dry. This indicates a perfectly gooey, chewy center.
• Cool Completely Before Cutting: Patience is a virtue, especially when it comes to cutting blondies! It’s absolutely crucial to allow the blondies to cool completely in the pan on a wire rack before attempting to slice them into squares. Cutting them while warm will likely result in crumbling, messy edges, and a less satisfying texture. Cooling allows them to set properly, ensuring clean, defined cuts and maintaining their ideal chewy consistency.
• Melt Butter with Care: When melting your butter, whether in the microwave or on the stovetop, do so slowly and gently. If using a microwave, use short, 15-20 second bursts, stirring in between. Overheating butter can cause the milk solids and fats to separate, which can negatively impact the final texture of your blondies. Aim for just melted, slightly warm butter.
• Gradually Incorporate Mix-ins: If you decide to add any additional mix-ins, like different types of chocolate (white, milk, dark), nuts (walnuts, pecans), or even sprinkles, fold them into the batter gently and gradually at the very end. This ensures that they are evenly distributed throughout the blondies, so every bite is packed with flavor and texture.
• Prioritize High-Quality Ingredients: The quality of your ingredients truly makes a difference in the final flavor and texture of your baked goods. For the best-tasting Oreo Blondies, opt for high-quality butter, a good vanilla extract (pure, not imitation), and your favorite brand of chocolate chips. Better ingredients will yield a richer, more nuanced flavor that elevates your blondies from good to unforgettable.

Variations and Customizations for Your Oreo Blondies

While the classic Oreo Blondies recipe is perfect as is, part of the joy of baking is making it your own! Here are some creative ideas to customize your blondies and keep things exciting:

• Chocolate Choices: Experiment with different types of chocolate chips! Try white chocolate chips for a sweeter, creamier contrast, milk chocolate chips for a softer melt, or even dark chocolate chunks for a more intense cocoa flavor. A mix of two or three types can be wonderfully complex.
• Nutty Additions: For an extra layer of crunch and flavor, fold in about ½ cup of chopped toasted pecans, walnuts, or almonds. The nutty notes will complement the buttery blondie base beautifully.
• Seasonal Twists: During the holidays, consider adding a sprinkle of crushed candy canes for a minty touch, or a swirl of caramel sauce before baking for a salted caramel Oreo blondie. For fall, a touch of pumpkin spice can be surprisingly delicious.
• Other Cookie Inclusions: Don’t limit yourself to just Oreos! Try using other crushed cookies like Biscoff, Nutter Butters, or even chocolate chip cookies for different flavor profiles and textures.
• Flavor Extracts: A small amount of almond extract can add a delightful depth, or a hint of peppermint extract could transform them into a holiday treat. Be careful not to overdo it with strong extracts.
• Cream Cheese Swirl: For an extra decadent touch, swirl about ¼ cup of sweetened cream cheese mixture (softened cream cheese, a tablespoon of sugar, and a dash of vanilla) into the batter before baking.

Serving Suggestions for Your Delicious Blondies

These Oreo Blondies are fantastic on their own, but a few simple additions can elevate them to an even more impressive dessert:

• Warm with Ice Cream: Serve a warm blondie square with a scoop of vanilla bean ice cream. The contrast between the warm, gooey blondie and the cold, melting ice cream is heavenly.
• Dust with Powdered Sugar: A light dusting of powdered sugar adds an elegant finish and a subtle extra touch of sweetness.
• Drizzled with Sauce: Drizzle with a homemade caramel sauce, chocolate sauce, or even a raspberry coulis for added flavor and visual appeal.
• With Coffee or Milk: These blondies are the perfect companion for a cup of coffee, a glass of cold milk, or even a hot chocolate.
• As a Dessert Platter Item: Cut into smaller bites and arrange them on a dessert platter with other treats for a party.

Storing and Freezing Your Oreo Blondies

Proper storage ensures your delicious Oreo Blondies stay fresh and enjoyable for as long as possible. Whether you plan to savor them over a few days or save them for a future craving, here’s how to do it right:

• Storing at Room Temperature: To store freshly baked Oreo Blondies, first allow them to cool completely in the pan. Once fully cooled, transfer them to an airtight container. They will remain wonderfully fresh, soft, and chewy at room temperature for up to 2-3 days. Make sure the container is truly airtight to prevent them from drying out.
• Refrigeration (Optional): If you prefer a firmer texture or live in a very warm climate, you can refrigerate them. Place the cooled blondies in an airtight container and store them in the refrigerator for up to 5-7 days. Bring them to room temperature or warm them slightly in the microwave for a few seconds before serving for the best texture.

Freezing – Oreo Blondies

Freezing is an excellent option for longer-term storage, allowing you to enjoy these treats weeks or even months later. To freeze, ensure your Oreo Blondies have cooled completely to prevent condensation and ice crystals from forming. For best results, flash freeze them: arrange the cut blondie squares in a single layer on a baking sheet and freeze for about 1-2 hours until they are firm. This prevents them from sticking together. Once firm, transfer the frozen blondies to a resealable freezer bag or an airtight freezer-safe container, separating each layer with parchment paper to prevent them from sticking to each other. Store the frozen blondies in the freezer for up to 2-3 months. When you’re ready to enjoy them, simply thaw them in the refrigerator overnight, or at room temperature for a few hours. For a warm, gooey treat, you can even gently reheat a thawed blondie in the microwave for 10-15 seconds.

Troubleshooting Common Blondie Issues

Even with the best intentions, baking can sometimes present challenges. Here are solutions to a few common problems you might encounter with Oreo Blondies:

• Blondies are Too Dry or Crumbly: This is often a sign of overbaking. Keep a close eye on your oven and rely on the toothpick test (moist crumbs, not wet batter) rather than just the timer. Another culprit could be too much flour; ensure you’re spooning and leveling your flour correctly.
• Blondies are Too Greasy: If your blondies feel overly greasy, it might be due to using too much butter or adding the melted butter while it was still too hot. Ensure your butter is cooled slightly to warm before mixing it in, and measure accurately.
• Blondies Aren’t Chewy Enough: The chewiness in blondies largely comes from brown sugar. If your blondies lack that signature chew, you might have used too much granulated sugar or overmixed the batter, which can develop gluten and lead to a cake-like texture.
• Blondies Sink in the Middle: A sunken center usually indicates that the blondies were undercooked. While a slight wobble is normal, a significant dip means they needed a bit more time in the oven to set properly.
• Oreo Pieces Settle at the Bottom: To prevent your chopped Oreos and chocolate chips from sinking, try tossing them with a tablespoon of flour before folding them into the batter. This helps them stay suspended evenly throughout the blondie.

Finally, once your Oreo Blondies are perfectly cooled and set, cutting them neatly is key for presentation. Use a sharp knife for clean cuts, and for the best results, wipe the knife clean with a damp cloth between each slice to prevent sticking and smearing. Start by cutting the entire pan of blondies in half to create two equal rectangles. Next, cut each of these rectangles in half again, yielding four larger squares. To get standard-sized individual portions, cut each of these four squares diagonally from one corner to the opposite corner. This method will give you 16 perfect, visually appealing triangular squares in total, ready to be enjoyed.

Ingredients

 

 

For the blondies

• ¾ cup unsalted butter melted and cooled slightly
• 1 cup light brown sugar packed
• ½ cup granulated sugar
• 1 large egg at room temperature
• 1 large egg yolk at room temperature
• 1 Tablespoon pure vanilla extract
• 1 teaspoon cornstarch
• ¼ teaspoon baking soda
• ¾ teaspoon salt
• 1¾ cup all-purpose flour spooned and leveled
• ¾ cup semisweet chocolate chips
• 12-14 Oreo cookies chopped into chunks

Instructions

 

• Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving an overhang on two sides to create handles. Use metal binder clips to secure the parchment to the pan sides. Set aside.
• In a large microwave-safe bowl, melt the butter, then let it cool slightly until just warm. To this butter, add the light brown sugar and granulated sugar. Whisk vigorously until the mixture is well combined, smooth, and slightly lightened in color. This process incorporates air and begins to build the signature blondie chewiness.
• Crack in the large egg and whisk vigorously for about 20 seconds. This vigorous mixing helps create that desirable crackly top crust. Then, add the egg yolk and repeat the whisking for another 20 seconds. Finally, stir in the pure vanilla extract until just combined.
• Using a rubber spatula, add the all-purpose flour, baking soda, cornstarch, and salt to the wet ingredients. Gently fold these dry ingredients into the wet mixture, stirring only until just combined and no dry streaks of flour are visible. Be careful not to overmix, as this can lead to tough blondies.
• Now, gently fold in your chopped Oreo cookies and semisweet chocolate chips. Distribute them evenly throughout the batter.
• Pour the prepared blondie batter into your lined 8×8 inch baking pan. Use the rubber spatula to spread the batter evenly across the pan for a uniform, finished look. For an extra enticing visual, consider sprinkling a few additional chocolate chips and chopped Oreo cookie pieces on top of the batter before baking.
• Bake the Oreo blondies for 30-35 minutes. Baking times can vary depending on your oven; in my oven, they were perfectly done at 35 minutes. The blondies are ready when the edges are set and lightly golden brown, and a toothpick inserted into the center comes out with a few moist crumbs attached (not wet batter). This indicates a perfectly gooey and chewy center.
• Once baked, remove the pan from the oven and place it on a wire rack. Allow the blondies to cool completely in the pan before attempting to lift them out and cut them into squares. This cooling process is essential for them to set properly and prevent crumbling, ensuring clean, perfect slices.
