These blondies are built on a base recipe I’ve relied on for years when I want that thick, chewy texture that sits somewhere between a cookie bar and a brownie. After making countless batches of blondies over the years, both in professional kitchens and at home, you start to recognize the formulas that actually work. This is the one I keep coming back to because it bakes up dense, gooey in the center, and perfectly rich without needing anything complicated!
For this version, I built the flavors around that trusted blondie base. Dark chocolate chips add richness, chunks of Oreo bring that classic cookies-and-cream crunch, and a small hint of espresso deepens the chocolate flavor without making the bars taste like coffee. It’s a combination that just works, layered, balanced, and exactly the kind of dessert I love baking when I want something simple but really satisfying.

Equipment
This blondies cookie recipe is in grams because using a kitchen scale for baking ensures precision and consistency. Measuring ingredients by weight is more accurate than using cups or spoons, which can vary depending on how they are filled. With a kitchen scale, you can be confident that you’re using the exact amount of each ingredient, leading to better and more reliable results every time you bake!
Oreo Blondies Ingredients
- Dark Brown Sugar: Dark brown sugar contains more molasses than light brown sugar, it adds moisture, contributing to the blondies' fudgy texture. I use it in my strawberry chocolate chip cookies and chocolate chip and butterscotch chip cookies too!
- Oreos: Oreos bring a classic, nostalgic flavor to the blondies, with their chocolatey crunch and creamy filling. They add both taste and texture, creating contrasts in each bite.
- Egg and Egg Yolk: The combination of a whole egg and an extra egg yolk adds to the fudginess of the blondies. The yolk contains fats and emulsifiers that enhance the dense, moist texture, while the egg white provides structure and stability.
- Espresso: A hint of espresso deepens the overall flavor profile, enhancing the taste of the chocolate and balancing the sweetness of the blondies. My espresso chocolate cookies and cupcakes with coffee are dreamy!
- All Purpose Flour: All-purpose flour is essential for the structure and consistency of the blondies. It provides the necessary gluten to hold the ingredients together while keeping the texture tender and chewy.

Oreo Blondies Variations
- Peanut Butter Chips: Swapping out some of the dark chocolate chips for peanut butter chips introduces a creamy, nutty flavor. The combination of chocolate, peanut butter, and Oreos is so too good!
- Coffee Flavored Oreos: Using coffee flavored Oreos instead of regular ones intensifies the espresso notes already present in the blondies.
- Golden Oreos: Use golden Oreos instead and omit the small amount of espresso! Add some almond extract if you like almond!
- Vanilla Ice Cream on Top: Serving your blondie bars warm with a scoop of vanilla ice cream on top takes them to the next level. The cold, creamy ice cream contrasts beautifully with the warm, gooey blondie, creating a delightful blend of temperatures and textures. This combination turns a simple blondie into an elegant dessert that's perfect for any occasion.

How to make Oreo Blondies
Step 1. Place the cooled down butter, instant espresso, dark brown sugar, granulated sugar, vanilla, egg, and egg yolk in a medium bowl. Beat until combined and smooth.
Step 2. Whisk together the salt and flour, add it to the wet ingredients. Mix until combined.
Step 3. Roughly chop the Oreos.
Step 4. Fold in the Oreos and dark chocolate chips.
Step 5. Pour into the pan, spreading it out evenly. Top with chopped Oreos (optional)
Step 6. Bake for 22-25 minutes or until the top is set and a toothpick has a few moist crumbs. Let it cool in the pan on the counter before cutting.
Hint: Place chocolate chips on top after the blondies come out of the oven for that pretty melty look.
Oreo Blondies Pro tips
- Underbake Slightly: To achieve the perfect gooey center, slightly underbake your blondies. When you insert a toothpick into the center, it should come out with a few moist crumbs but not wet batter. Blondies continue to cook as they cool, so taking them out a bit early ensures they stay moist and fudgy.
- Let Cool: Allowing your blondies to cool before slicing is crucial because it lets them set properly, making them easier to cut into neat squares without falling apart. Cooling also enhances the flavors, allowing the ingredients to meld together.
- Do Not Overmix: When combining the wet and dry ingredients, mix just until the flour is incorporated. Overmixing can lead to tougher blondies because it develops the gluten in the flour.
- Parchment Paper: Always line your pan with parchment paper for easy removal and clean up!
Oreo Blondies FAQs
Why are my blondies dry?
Over baking them causes blondies to dry out. The top should look just set and a toothpick should have a few moist crumbs. They will continue baking in the pan on the counter.
Are blondies supposed to be gooey?
Yes! I do not believe in cakey blondies. The best part of a blondie is the fudgy gooey texture!
Should I refrigerate these Oreo blondies?
No, refrigerating baked goods dries them out. Leaving them out in an airtight container at room temperature is best.
