Ingredients You’ll Need

1½ cups all-purpose flour (spooned and leveled or weighed): This classic flour forms the base of the cookie and brownie combo. If you don’t have all-purpose flour, you can use gluten-free flour with good results.
½ teaspoon baking powder: This helps the cookies rise slightly, giving them the right texture. Make sure it’s fresh for the best results.
¼ teaspoon salt: A touch of salt enhances the sweetness and balances flavors perfectly.
½ cup unsalted butter (softened): Using softened butter creates a creamy, luscious batter. For a substitute, use coconut oil or vegan butter.
½ cup granulated sugar: Adds sweetness and helps create that delightful cookie texture.
⅓ cup light brown sugar (packed): The molasses in brown sugar adds moisture and depth of flavor. You can replace it with an equal amount of granulated sugar if needed.
1 large egg: Provides structure. Ensure it’s at room temperature for easier mixing.
1 teaspoon pure vanilla extract: The key flavor booster; always opt for pure extract for the best taste.
½ cup mini M&M’s (plus a few more for topping): These cuties not only add sweetness but also a visual appeal. You can use chocolate chips as an alternative.
⅓ cup chocolate chips (plus a few more for topping): Go for semi-sweet for a harmonizing flavor. You can mix up the types for more complexity—dark, milk, or even white chocolate chips work well.
½ cup unsalted butter (cut into eight pieces): This gets melted for the brownie batter, providing that rich, fudgy consistency.
1 cup light brown sugar (packed): The second round of brown sugar reinforces the brownie aspect of these brookies.
2 large eggs: Essential for perfectly fudgy brownie texture, use at room temperature.
½ cup all-purpose flour (spooned and leveled or weighed): Helps thicken the brownie batter without overpowering.
⅓ cup unsweetened cocoa powder: This contributes to that deep, rich chocolate flavor.
½ teaspoon salt: Just a pinch to balance the sweetness in the brownies.
1 teaspoon cornstarch: Provides moisture and keeps the brownies soft.
½ cup chocolate chips: Adding even more chocolaty goodness!

How to Make M&M Brookies (Brownie Cookies)

Preheat the Oven: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat to prevent sticking.
Mix Cookie Ingredients: In a mixing bowl, whisk together 1½ cups all-purpose flour, ½ teaspoon baking powder, and ¼ teaspoon salt. In a separate bowl, cream together ½ cup softened unsalted butter, ½ cup granulated sugar, and ⅓ cup packed light brown sugar until light and fluffy.
Add the Egg and Vanilla: Beat in 1 large egg and 1 teaspoon pure vanilla extract until well combined. Gradually mix in the flour mixture until just combined. Gently fold in ½ cup mini M&M’s and ⅓ cup chocolate chips.
Scoop the Cookie Dough: Use a tablespoon or cookie scoop to drop rounded tablespoons of dough onto the prepared baking sheet, spacing them about 2 inches apart. Place a few extra M&M’s and chocolate chips on top if desired.
Prepare Brownie Mixture: In a microwave-safe bowl, melt ½ cup unsalted butter, then stir in 1 cup packed light brown sugar until smooth. Allow it to cool slightly, then whisk in 2 large eggs and 1 teaspoon pure vanilla extract.
Combine Brownie Ingredients: In another bowl, whisk together ½ cup all-purpose flour, ⅓ cup unsweetened cocoa powder, ½ teaspoon salt, and 1 teaspoon cornstarch. Gradually mix the dry ingredients into the melted butter mixture until combined. Stir in ½ cup chocolate chips.
Layer the Brownie Batter: Carefully spoon or spread some brownie batter over each cookie mound on the baking sheet. Make sure the brownie layer isn’t too thick; it acts as the perfect topping rather than a heavy layer.
Bake the Brookies: Bake in the preheated oven for 28-33 minutes, or until the edges start to bubble and are set but the centers still appear slightly underbaked. They will continue cooking on the baking sheet after removing from the oven.
Cool and Serve: Allow the M&M Brookies to cool on the baking sheet for around 10 minutes before transferring to a wire rack to cool completely. Enjoy them warm or store for later!

Storing & Reheating

To keep your M&M Brookies fresh, store them at room temperature in an airtight container for up to 4 days. If you want to keep them longer, refrigerate them for about a week or freeze them for up to 3 months. For frozen brookies, place them in a freezer-friendly bag, ensuring all air is removed. To reheat, pop them in a preheated oven at 350°F (175°C) for about 5-10 minutes, or until warm. Keep in mind that freezing might slightly alter their texture; a quick zap in the microwave can help refresh their fudginess.

Chef’s Helpful Tips

Make sure your butter is softened, but not melted, for the best mixing results.
Avoid overmixing after adding eggs to maintain a tender texture.
If you like your brookies a bit more cake-like, add an additional 2 tablespoons of flour to the brownie batter.
For an extra touch, sprinkle some sea salt on top after baking for a delightful contrast to the sweetness.
Experiment with different types of chocolate chips or M&M’s for variety.
These brookies can also be mixed with nuts or dried fruits for added flavor and texture.

The combination of brownies and cookies in M&M Brookies truly makes for a playful dessert option. The dense, fudgy brownie on top perfectly contrasts with the chewy cookie base, creating a wonderful experience with every bite. Take this opportunity to swap in flavors you enjoy, maybe swirling in some peanut butter or using your favorite candy instead of M&M’s. Most importantly, enjoy sharing (or not!) these sweet treats with loved ones.

Recipe FAQs

Absolutely! Feel free to use dark chocolate chips, white chocolate, or even mix in some butterscotch chips. The flavor combinations are limitless—you could even experiment with mint or peanut butter chips!

Brookies are done when the edges appear set and slightly browned, while the center may look slightly underbaked. They will continue to cook after being removed from the oven, giving you that perfect fudgy texture.

Yes! Ensure they’re completely cooled before placing them in a freezer-safe container or bag. They can be frozen for up to 3 months. Just thaw them overnight in the refrigerator and reheat them when you’re ready to enjoy!
