Why You’ll Love This Recipe

  • Rich Chocolate Flavor: Combines melted semi-sweet chocolate morsels and unsweetened cocoa powder for a deep, indulgent taste.

  • Fudgy Texture: Melted butter ensures a moist and chewy consistency, steering clear of a cake-like crumb.

  • Festive and Customizable: Incorporate your favorite M&M's varieties or color themes to suit holidays and special events.

  • Simple Preparation: Made in one saucepan, minimizing cleanup and simplifying the baking process.

Ingredients

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

  • Unsalted butter

  • Semi-sweet chocolate morsels

  • Granulated sugar

  • Large eggs

  • Vanilla extract

  • Unsweetened cocoa powder

  • All-purpose flour

  • Kosher salt

  • Baking powder

  • M&M's candies

Directions

  1. Preheat Oven: Set your oven to 350°F (175°C). Line a 9-inch square baking dish with parchment paper for easy removal.

  2. Melt Butter and Chocolate: In a medium saucepan over medium heat, melt the unsalted butter. Remove from heat and stir in half of the semi-sweet chocolate morsels and granulated sugar until smooth and the chocolate is fully melted.

  3. Incorporate Eggs and Vanilla: Add the eggs one at a time to the mixture, stirring well after each addition. Mix in the vanilla extract.

  4. Add Dry Ingredients: Gently fold in the unsweetened cocoa powder, all-purpose flour, kosher salt, and baking powder. Stir just until combined; avoid overmixing to maintain a fudgy texture.

  5. Fold in M&M's: Incorporate half of the M&M's candies into the batter.

  6. Bake: Pour the batter into the prepared baking dish, smoothing the top. Sprinkle the remaining M&M's and semi-sweet chocolate morsels over the surface. Bake for approximately 38 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.

  7. Cool and Serve: Allow the brownies to cool completely in the pan before slicing into squares.

Servings and Timing

  • Servings: 9 large brownies

  • Prep Time: 10 minutes

  • Cook Time: 38 minutes

  • Total Time: 48 minutes

Variations

  • Nutty Addition: Fold in chopped nuts like walnuts or pecans for added crunch and flavor.

  • Different M&M's Varieties: Experiment with peanut, peanut butter, or seasonal M&M's to customize the taste and appearance.

  • Layered Delight: Add a layer of caramel or peanut butter between the brownie batter for an extra indulgent treat.

Storage/Reheating

  • Storage: Keep the brownies in an airtight container at room temperature for up to one week.

  • Freezing: Wrap individual brownies in plastic wrap and place them in a freezer-safe bag. They can be frozen for up to three months. Thaw at room temperature before serving.

  • Reheating: For a warm treat, microwave a brownie on high for 10-15 seconds.

FAQs

How do I prevent my brownies from becoming cakey?

To achieve a fudgy texture, avoid overmixing the batter after adding the dry ingredients, and ensure you're using melted butter as specified.

Can I use Dutch-processed cocoa powder instead of unsweetened cocoa powder?

It's best to use unsweetened cocoa powder as the recipe is formulated for it. Dutch-processed cocoa has a different acidity level, which may affect the brownies' texture and rise.

What’s the best way to cut brownies cleanly?

Use a plastic knife to cut completely cooled brownies. This helps achieve clean cuts without tearing.

Can I double this recipe?

Yes, you can double the ingredients and bake the brownies in a 9x13-inch pan. Adjust the baking time accordingly, checking for doneness with a toothpick.

How can I tell when the brownies are done baking?

Insert a toothpick into the center; if it comes out with a few moist crumbs, the brownies are ready. They will continue to set as they cool.

Can I add frosting to these brownies?

Absolutely! A chocolate ganache or cream cheese frosting would complement the M&M's and add extra richness.

Are these brownies suitable for nut allergies?

If you use plain M&M's and ensure all other ingredients are free from nuts, the brownies should be nut-free. Always check labels to be certain.

Can I use margarine instead of butter?

For the best flavor and texture, it's recommended to use unsalted butter. Margarine may alter the taste and consistency.

How do I make these brownies gluten-free?

Substitute the all-purpose flour with a gluten-free flour blend designed for baking. Ensure all other ingredients, including M&M's, are certified gluten-free.

Can I add other mix-ins to the batter?

Yes, feel free to add chocolate chips, white chocolate chunks, or even dried fruit to customize the brownies to your liking.

Conclusion

These M&M's Brownies are a delightful combination of rich chocolate flavor and colorful fun. Their chewy, fudgy texture makes them a favorite for both kids and adults alike, and their versatility allows you to customize them with your favorite add-ins. Whether for a birthday, holiday, or a simple treat, these brownies are sure to impress.
