Brookies are the ultimate dessert for anyone who can’t decide between brownies or cookies. The combination of rich, fudgy brownies and soft, chewy cookies gives you the best of both worlds. With simple ingredients and easy-to-follow instructions, this recipe guarantees a perfect dessert every time. The fudgy texture of the brownie part pairs perfectly with the chewy cookie dough, making each bite a little piece of heaven. Plus, they’re a crowd-pleaser, making them a great choice for family gatherings, parties, or just a sweet treat at home.

Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

For the brownie layer:

  • ½ cup unsalted butter, melted

  • 1 cup granulated sugar

  • 2 large eggs

  • 1 teaspoon vanilla extract

  • ½ cup all-purpose flour

  • ⅓ cup cocoa powder

  • ¼ teaspoon salt

  • ¼ teaspoon baking powder

For the cookie dough layer:

  • ½ cup unsalted butter, softened

  • ¼ cup granulated sugar

  • ½ cup brown sugar, packed

  • 1 large egg

  • 1 teaspoon vanilla extract

  • 1 ½ cups all-purpose flour

  • ½ teaspoon baking soda

  • ¼ teaspoon salt

  • 1 cup chocolate chips

Directions

  1. Preheat the oven to 350°F (175°C). Grease a 9x9-inch baking pan or line it with parchment paper.

  2. Prepare the brownie layer by whisking together melted butter, sugar, eggs, and vanilla extract in a medium bowl. Sift in the flour, cocoa powder, salt, and baking powder. Stir until smooth and combined. Set aside.

  3. Prepare the cookie dough layer by beating the softened butter, granulated sugar, and brown sugar in a large bowl until light and fluffy. Add in the egg and vanilla extract, mixing until well combined. Gradually add the flour, baking soda, and salt, mixing just until incorporated. Fold in the chocolate chips.

  4. Spread the brownie batter evenly in the prepared pan. Then, drop spoonfuls of cookie dough over the brownie layer. Use a knife or spatula to swirl the cookie dough into the brownie batter, creating a marbled effect.

  5. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out mostly clean (it may have a few moist crumbs).

  6. Allow the brookies to cool completely in the pan before slicing into squares.

Servings and Timing

  • Servings: 12-16

  • Prep Time: 15 minutes

  • Cook Time: 30-35 minutes

  • Total Time: 50 minutes

Variations

  • Nutty Brookies: Add chopped walnuts or pecans to the brownie layer for an extra crunch.

  • Peanut Butter Swirl: Swirl in some peanut butter into the brownie or cookie dough layers for a nutty twist.

  • Caramel Brookies: Drizzle caramel sauce on top before baking for an added layer of flavor.

  • Gluten-Free Brookies: Substitute the all-purpose flour with a gluten-free flour blend to make these brookies gluten-free.

Storage/Reheating

  • Storage: Store leftover brookies in an airtight container at room temperature for up to 3-4 days. You can also refrigerate them for a longer shelf life.

  • Freezing: These brookies freeze well. Wrap individual pieces in plastic wrap and store them in a zip-top bag for up to 3 months. To thaw, let them sit at room temperature for 30 minutes or microwave them for 20-30 seconds.

  • Reheating: To reheat brookies, microwave them for 10-15 seconds or warm them in the oven at 350°F for about 5-7 minutes.

FAQs

1. Can I use dark chocolate in this recipe?

Yes, you can substitute dark chocolate or use a combination of milk and dark chocolate for a richer flavor.

2. Can I use margarine instead of butter?

While butter is recommended for the best flavor, margarine can be used as a substitute in a pinch, though it may alter the texture slightly.

3. How do I prevent my brookies from being too dry?

Be sure not to overbake them! Check them with a toothpick after 30 minutes, and if it comes out mostly clean with a few moist crumbs, they’re done.

4. Can I add other mix-ins like M&Ms or crushed Oreos?

Absolutely! You can get creative with the add-ins. Just make sure to fold them into the cookie dough layer.

5. Can I make these in a larger pan?

If you use a larger pan, the brookies may bake faster, so keep an eye on them and adjust the baking time accordingly.

6. How can I make sure the cookie dough stays soft?

Underbake the cookie dough slightly to ensure it stays soft and chewy once cooled.

7. Can I double this recipe for a larger batch?

Yes, simply double the ingredients and bake in a 9x13-inch pan, increasing the baking time slightly.

8. Can I use a different type of chocolate for the chips?

You can use milk chocolate, white chocolate, or even butterscotch chips for a different flavor profile.

9. Why does my brownie layer look uneven?

This can happen if the brownie batter is spread too thickly or unevenly. Try spreading it out evenly before adding the cookie dough layer.

10. Can I make this recipe in advance?

Yes, you can prepare the brookies ahead of time and store them in an airtight container until you’re ready to serve.

Conclusion

These fudgy, chewy brookies are the perfect combination of two favorite treats. With their rich, gooey brownie base and soft, chocolate-chip cookie top, they’re sure to become a go-to recipe for any dessert lover. Whether you’re making them for a family gathering or enjoying them on your own, brookies are a crowd-pleaser that never disappoints. So, whip up this delicious treat, and indulge in the best of both worlds!
