Brookie (Brownie + Cookie Bar)

A decadent fusion of two classic desserts, the Brookie combines the richness of a fudgy brownie with the chewy delight of a chocolate chip cookie. With crispy edges and a soft, molten center, this layered treat is the perfect solution for anyone who can’t choose between cookies and brownies.

Why You’ll Love This Recipe

The Brookie is the ultimate crowd-pleaser, offering the best of both worlds in every bite. The brownie base is dense, moist, and intensely chocolaty, while the cookie top adds a sweet, buttery crunch with bursts of melted chocolate chips. It’s a simple yet indulgent dessert that’s great for potlucks, parties, or satisfying an everyday craving. Best of all, it comes together easily in one pan.

Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

For the brownie layer:

  • unsalted butter, melted
  • granulated sugar
  • large eggs
  • vanilla extract
  • unsweetened cocoa powder
  • all-purpose flour
  • salt
  • baking powder

For the cookie layer:

  • unsalted butter, softened
  • brown sugar
  • granulated sugar
  • egg
  • vanilla extract
  • all-purpose flour
  • baking soda
  • salt
  • chocolate chips

Directions

  1. Preheat oven to 350°F (175°C). Grease and line an 8×8 inch baking dish with parchment paper.
  2. Make the brownie layer: In a mixing bowl, whisk together the melted butter and granulated sugar. Add the eggs and vanilla extract and mix well.
  3. Stir in the cocoa powder, flour, salt, and baking powder until just combined. Spread the brownie batter evenly in the prepared baking pan.
  4. Make the cookie layer: In another bowl, cream the softened butter with brown and granulated sugars until light and fluffy.
  5. Beat in the egg and vanilla extract. Stir in the flour, baking soda, salt, and chocolate chips until the dough is well mixed.
  6. Drop spoonfuls of cookie dough on top of the brownie layer and gently spread or press it down to cover the surface.
  7. Bake for 30–35 minutes or until the top is golden and just set. The center may appear slightly gooey—this ensures a chewy texture.
  8. Allow to cool in the pan before slicing. Serve slightly warm for the best flavor and texture.

Variations

Storage/Reheating

FAQs

Can I use boxed brownie mix?

Yes, a boxed mix can save time. Just prepare as directed and top with the cookie dough layer before baking.

How do I know when the brookies are done?

The top should be golden brown and set. The center may look slightly underdone but will firm up as it cools.

Can I double the recipe?

Yes, double the ingredients and bake in a 9×13 inch pan. Adjust the baking time to about 40–45 minutes.

Can I use only egg yolks or whites?

This recipe works best with whole eggs to maintain the right texture and structure.

What type of chocolate chips are best?

Semi-sweet chips are classic, but milk or dark chocolate chips work well based on preference.

Can I add caramel to the recipe?

Yes, drizzle caramel sauce between the layers before baking or over the top once baked.

Do I need to chill the dough?

No chilling is required for this recipe. It’s designed to be baked immediately after preparation.

Can I use a different pan size?

An 8×8 inch pan is ideal. If using a larger pan, expect thinner layers and reduced baking time.

Are brookies supposed to be gooey in the center?

Yes, a slightly gooey center is typical and desirable for a chewy, rich texture.

Can I make this dairy-free?

Yes, use dairy-free butter and chocolate chips to adapt the recipe for dairy-free diets.
