What Makes These Brookie Bars So Special?

Brookies have been around for a while, but adding crushed Oreos takes them to another level. The contrast of textures—soft cookie dough, gooey brownie, and crispy Oreo bits—creates a layered dessert that is as visually appealing as it is delicious.

What sets these bars apart?
✔️ A chewy, golden cookie dough layer loaded with Oreo chunks
✔️ A rich and fudgy brownie base made with melted chocolate and cocoa powder
✔️ The perfect mix of textures—crisp on the edges, soft in the center
✔️ Customizable flavors—easy to adapt with mix-ins like chocolate chips or nuts

Ingredients

For the Cookie Dough:

6 tbsp unsalted butter, room temperature
½ cup light brown sugar, packed
⅛ cup granulated sugar
1 large egg yolk, room temperature
1 tsp vanilla extract
¾ cup + 2 tbsp all-purpose flour
½ tsp fine sea salt
½ tsp baking soda
4 Oreos, chopped (plus more for topping)

For the Brownie Batter:

4 tbsp unsalted butter
⅓ cup semi-sweet chocolate chips
¼ cup + ⅛ cup granulated sugar
1 large egg, room temperature
1 tsp vanilla extract
¼ cup all-purpose flour
¼ cup unsweetened cocoa powder
¼ tsp fine sea salt

Directions

Preheat the Oven: Set the oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper.
Prepare the Cookie Dough: In a bowl, beat the butter, brown sugar, and granulated sugar until light and fluffy. Mix in the egg yolk and vanilla. Stir in the flour, salt, and baking soda, then fold in the chopped Oreos. Set aside.
Make the Brownie Batter: Melt the butter and chocolate chips together, stirring until smooth. Whisk in the sugar, egg, and vanilla. Fold in the flour, cocoa powder, and salt until combined.
Assemble the Layers: Spread the brownie batter evenly into the prepared pan. Drop spoonfuls of the cookie dough on top, gently spreading it to cover most of the brownie layer. Press additional Oreo pieces on top.
Bake to Perfection: Bake for 25-30 minutes or until the edges are set but the center is slightly gooey. Let cool before slicing into bars.

Tips for Making the Perfect Oreo Brookie Bars

Getting the perfect balance between the cookie and brownie layers is key. Here are some expert tips to ensure success:

1. Layering Matters

Since cookie dough is thicker and more structured, it doesn’t spread as much as brownie batter. To ensure an even layer:

Gently press spoonfuls of cookie dough over the brownie batter rather than spreading it aggressively.
Leave some areas of brownie exposed for a marbled effect when baked.

2. Don’t Overmix the Brownie Batter

For a fudgy, dense brownie base, avoid overmixing once you add the flour. Overworking the batter incorporates too much air, leading to a cakier texture.

3. Get the Bake Time Just Right

If you like gooey brookies, bake until the edges are set but the center is slightly underbaked.
For firmer bars, extend the baking time by 5-7 minutes.
Always let the brookies cool completely before slicing to get clean, neat squares.

4. Choosing the Right Oreos

You can customize this recipe by using different Oreo varieties:

Double Stuf Oreos for extra creaminess
Golden Oreos for a vanilla twist
Mint Oreos for a refreshing contrast
Birthday Cake Oreos for a fun, festive vibe

How to Serve Oreo Brookie Bars

These bars are delicious on their own, but you can elevate them with a few serving ideas:

Classic & Simple

Serve warm with a glass of milk for the ultimate comfort treat.
Dust lightly with powdered sugar for a bakery-style finish.

Indulgent Dessert Ideas

Top with vanilla ice cream and drizzle with chocolate sauce for an Oreo Brookie Sundae.
Layer pieces of brookies into a trifle with whipped cream and extra Oreos.

Frequently Asked Questions (FAQs)

Yes! If you’re short on time, pre-made cookie dough works well. Just press it evenly over the brownie layer and bake as directed.

2. How Do I Get the Perfect Texture?

For gooey brookies, slightly underbake them and let them cool before slicing. For firmer bars, bake until fully set and refrigerate before cutting.

3. Can I Make These in Advance?

Yes! These bars taste even better the next day as the flavors meld together. Store them at room temperature for up to 3 days or refrigerate for up to a week.

4. How Do I Store Leftovers?

Room Temperature: Keep in an airtight container for up to 3 days.
Refrigerator: Store for up to a week to maintain freshness.
Freezer: Wrap individual bars in plastic wrap and freeze for up to 2 months. Thaw at room temperature before serving.

5. Can I Double the Recipe?

Absolutely! Use a 9×13-inch pan and double all ingredients. Baking time may need to be extended by 5-10 minutes.

6. Can I Use Different Types of Chocolate?

Yes! Instead of semi-sweet chocolate chips, try:

Dark chocolate for a richer, slightly bitter contrast
Milk chocolate for a sweeter, creamier flavor
White chocolate chips for a cookies-and-cream-style brookie

7. What’s the Best Way to Cut Clean Slices?

Let the brookies cool completely before slicing.
Use a sharp knife, wiping it clean between cuts.
If needed, refrigerate for 30 minutes before slicing for neater edges.

8. Can I Make These Gluten-Free?

Yes! Substitute all-purpose flour with a gluten-free 1:1 baking flour and use gluten-free Oreos.

9. Can I Make These Without Eggs?

For an egg-free version, use:

1 tablespoon ground flaxseed + 3 tablespoons water per egg (let sit for 5 minutes).
1 mashed banana for a subtle fruit flavor.

10. What If I Don’t Have a Hand Mixer?

No problem! You can mix everything by hand using a whisk and spatula. Just make sure the butter is fully softened for easy blending.
