How to Make M&M Brookies (Brownie Cookies)

Preheat the Oven: Heat your oven to 350°F (175°C) to get it nice and toasty.
Mix the Dry Ingredients: In a bowl, whisk together 1½ cups all-purpose flour, ½ teaspoon baking powder, and ¼ teaspoon salt until well combined.
Cream the Butters and Sugars: In a large bowl, cream together ½ cup softened unsalted butter with ½ cup granulated sugar and ⅓ cup light brown sugar until light and fluffy.
Add Egg & Vanilla: Beat in 1 large egg and 1 teaspoon vanilla extract until fully incorporated.
Combine with Dry Ingredients: Gradually mix the dry ingredients into the butter mixture until just combined.
Fold in M&M’s and Chocolate Chips: Carefully incorporate ½ cup mini M&M’s and ⅓ cup chocolate chips into the cookie dough. Set aside.
Make the Brownie Batter: In a medium saucepan over low heat, melt ½ cup unsalted butter until fully melted.
Combine Brownie Ingredients: Stir in 1 cup packed light brown sugar, 2 large eggs, and 1 teaspoon vanilla extract until smooth.
Add Cocoa & Dry Ingredients: Stir in ½ cup all-purpose flour, ⅓ cup unsweetened cocoa powder, ½ teaspoon salt, and 1 teaspoon cornstarch until smooth.
Fold in Chocolate Chips: Add ½ cup chocolate chips to the brownie batter for an extra chocolaty burst.
Layer the Two Mixtures: In a greased 9×13-inch baking pan, spoon dollops of the brownie batter followed by spoonfuls of the cookie dough, swirling them together gently for a marbled effect.
Bake: Bake in the preheated oven for 26–33 minutes or until the edges are golden and a toothpick inserted in the center comes out with moist crumbs.
Cool and Garnish: Once removed from the oven, let cool slightly. Top with additional M&M’s and chocolate chips for that extra special touch. Slice them up and enjoy warm!

Storing & Reheating

To keep your M&M Brookies fresh, store them at room temperature in an airtight container for up to 3 days. If you’d like to extend their life, refrigerate them for up to a week, but use a container that won’t squish the cookies. For long-term storage, you can freeze these delicious treats for up to 3 months. Simply wrap them tightly in plastic wrap and place them in a freezer bag. When ready to enjoy, reheat in the microwave for about 15–20 seconds or until warmed through. Keep in mind that the texture may change slightly when reheated, but they’ll still be delightful!

Chef’s Helpful Tips

Make sure your butter is at room temperature for easy creaming.
Avoid over-mixing the cookie dough; this keeps them tender.
If using cold butter for the brownie batter, melting it gently helps keep it smooth.
For added texture, mix in some nuts or shredded coconut.
Add a pinch of espresso powder to enhance the chocolate flavor.
Consider making double batches to share with friends or freeze for later!

M&M Brookies are not just a delicious treat, but they’re also so customizable! I hope this recipe inspires you to take a leap in the kitchen.

Recipe FAQs

Can I use all-purpose flour for the brownies instead of cake flour?

Absolutely! All-purpose flour works perfectly fine for the brownies in this recipe. It will produce a lovely, chewy texture. Just ensure you measure it accurately for the best results.

How can I modify the recipe for gluten-free options?

You can substitute all-purpose flour with a 1:1 gluten-free flour blend for both the cookie and brownie components. Make sure the baking powder is also gluten-free, and you’re all set!

Can I make the cookie dough or brownie batter ahead of time?

Yes! You can prepare the dough or batter ahead of time and refrigerate it for up to 2 days before baking. Just be sure to cover it tightly to maintain freshness.

Are these cookies supposed to be soft in the center?

Yes! The M&M Brookies should be slightly underbaked in the center for a fudgy consistency. Once they cool down, they’ll set up nicely, giving you that perfect chewy texture.
