  • Fudgy and Flavorful: The combo of melted butter and chocolate with both brown and granulated sugar creates a deeply rich brownie base.
  • Colorful Fun: M&M candies add a cheerful crunch and playful appearance that makes these brownies irresistible to kids and adults alike.
  • Easy to Make: Using a double boiler for melting helps you avoid burned chocolate and gets the batter smooth and shiny every time.

Ingredients You’ll Need

Each ingredient in this M&M Brownies Recipe plays a specific role to create that indulgent texture and flavor you’re craving. I like to pick good quality Dutch process cocoa powder and real unsalted butter to ensure the deepest chocolate taste. The M&Ms add more than color—they give extra texture and bursts of sweetness that pairs perfectly with the fudge.

Flat lay of a small slab of unsalted butter, a few pieces of semi-sweet chopped chocolate, a small white bowl with light brown sugar, a small white bowl with granulated sugar, four whole uncracked brown eggs, a small mound of Dutch process cocoa powder, a small white bowl with vanilla extract, a small pile of all-purpose flour, a small handful of colorful M&M chocolate candies, a pinch of salt crystals placed near the cocoa powder, all arranged symmetrically on simple white ceramic dishes and bowls, placed on a clean white marble surface, soft natural light, photo taken with an iPhone, professional food photography style, fresh ingredients, white ceramic bowls, no bottles, no duplicates, no utensils, no packaging --ar 2:3 --v 7 --p m7354615311229779997 - M&M Brownies, chocolate candy brownies, fudgy brownies with M&Ms, homemade M&M brownies, colorful brownie treat
  • Unsalted Butter: Using unsalted lets you control the salt level and helps create a silky, rich batter.
  • Semi-sweet Chocolate: Adds an extra layer of chocolate depth beyond the cocoa powder.
  • Light Brown Sugar: Brings moisture and a subtle caramel flavor that keeps brownies chewy.
  • Granulated Sugar: Balances sweetness and helps with that perfect melt in your mouth texture.
  • Large Eggs: At room temperature, they emulsify beautifully for a smooth batter.
  • Dutch Process Cocoa Powder: Gives a rich, mellow chocolate flavor and darker color compared to natural cocoa.
  • Salt: Enhances the chocolate flavor—don’t skip it!
  • Vanilla Extract: The perfect little flavor boost that rounds everything out.
  • All-purpose Flour: Spoon and level for accuracy; over mixing can toughen your brownies.
  • M&M Chocolate Candies: For that fun, colorful crunch on top and throughout.

Variations

One of the things I adore about this M&M Brownies Recipe is how easy it is to make your own with little tweaks. You can swap out ingredients or add extras depending on what you have on hand or your personal preferences. Feel free to get creative—these brownies are forgiving and perfect for customization.

  • Peanut Butter Swirl: Once, I gently folded in dollops of peanut butter before baking, and it was a game changer—creamy meets chocolaty in every bite.
  • Nutty Crunch: Mixing in chopped walnuts or pecans with the flour adds a wonderful texture contrast.
  • Milk Chocolate M&Ms: I often use milk chocolate M&Ms for an even sweeter pop, especially if baking for kids.
  • Gluten-Free Option: Substitute the all-purpose flour with a gluten-free blend, but don’t overmix to keep the fudginess intact.

How to Make M&M Brownies Recipe

Step 1: Prep your Pan and Oven

Start by preheating your oven to 350°F. I like to spray an 8×8 inch baking pan with non-stick spray, then line it with parchment paper leaving some overhang on the sides. This simple step makes lifting the brownies out later a breeze—no crumbling or sticking to the pan!

Step 2: Melt Butter, Chocolate, and Sugars

The real magic starts with gently melting the unsalted butter, chopped semi-sweet chocolate, light brown sugar, and granulated sugar together using a double boiler. This soft, warm mixture can look grainy at first, but that’s totally normal—just be sure to stir frequently so everything melts evenly without burning. If you’ve ever scorched chocolate, you’ll appreciate this slow and steady approach!

Step 3: Whisk in the Eggs

Once the chocolate mixture has cooled slightly but is still warm, it’s time to whisk in the eggs, one at a time. I love this part because the batter starts to lighten and get glossy, which means you’re on the right track. Don’t rush—whisking well ensures your brownies have that shiny, fudgy texture we all adore.

Step 4: Add Cocoa Powder, Salt, and Vanilla

Then stir in the Dutch process cocoa powder, salt, and vanilla extract until everything is well combined. This gives your brownies that rich, deep chocolate flavor with a perfect balance of sweet and salty notes.

Step 5: Fold in the Flour

Now for the trickiest part—adding the flour. Using a large spatula, gently fold the flour into the batter until just a few streaks remain. Overmixing here can toughen the brownies, so patience is key. You want the batter to be thick and luxurious but not dense.

Step 6: Bake and Add M&Ms

Transfer the batter into your prepared pan and smooth it out with an offset spatula. Then sprinkle those colorful M&M chocolate candies generously over the top—they’ll get beautifully melty around the edges while staying perfectly crunchy on top. Bake for 45 to 50 minutes. I like to check at 45 minutes by inserting a toothpick about two inches from the side; you’re aiming for a few moist crumbs, not wet batter. This keeps the center fudgy, never dry or cakey.

Step 7: Cool Completely Before Cutting

This is a tough one—I get it, brownies smell amazing right out of the oven! But for the cleanest slices and the best texture, let the pan cool on a wire rack completely. Using the parchment overhang, lift the whole slab out for easy cutting into squares. I promise it’s worth the wait.

Pro Tips for Making M&M Brownies Recipe

  • Use a Double Boiler: This method prevents your chocolate from burning and keeps the butter from separating—I’ve found it makes all the difference in silky-smooth batter.
  • Don’t Overmix the Flour: Stirring just until combined keeps the brownies tender and fudgy rather than tough and cakey.
  • Check for Doneness Early: Ovens vary, so start checking at 45 minutes with a toothpick; leaving brownies in too long dries them out.
  • Cool Completely: Trust me, letting the brownies cool fully before cutting gives you cleaner slices and sets the texture to perfection.

How to Serve M&M Brownies Recipe

M&M Brownies Recipe - Serving

Garnishes

I like to keep it simple and let the vibrant M&Ms shine on these brownies. Occasionally, I dust them lightly with powdered sugar before serving for a touch of elegance. You can also drizzle a bit of melted dark chocolate or caramel sauce for an extra decadent touch that turns these brownies into a special dessert.

Side Dishes

These brownies pair beautifully with a scoop of vanilla ice cream or a dollop of whipped cream—my family goes crazy for this combo! A hot cup of coffee or a cold glass of milk also elevates the experience, rounding out the sweet richness perfectly.

Creative Ways to Present

For parties, I love arranging these brownies on a pretty platter with ribbons of colorful frosting drizzled over them. Wrapping individual squares in parchment and tieing with twine makes for adorable grab-and-go party favors. And if you’re making these for a kid’s birthday, adding themed sprinkles along with the M&Ms is always a hit.

Make Ahead and Storage

Storing Leftovers

I usually keep leftovers in an airtight container at room temperature for up to 3 days, but honestly, these brownies disappear fast! If you want to keep them fresh longer, storing in the fridge extends life up to 5 days without sacrificing too much softness.

Freezing

These brownies freeze beautifully. I slice them into squares first, then wrap each piece individually in plastic wrap and place them in a freezer bag. When you’re ready, thaw at room temperature for a few hours or overnight—you’ll find they taste just as amazing as fresh.

Reheating

If you want to enjoy your brownies warm, popping a slice in the microwave for about 10 seconds (no more!) brings back that soft, gooey texture. Adding a scoop of ice cream on top after warming? Pure bliss.

FAQs

  1. Can I use regular cocoa powder instead of Dutch process in the M&M Brownies Recipe?

    Yes, you can substitute regular cocoa powder, but Dutch process cocoa gives a smoother, richer flavor and darker color. If you use natural cocoa, the brownies may taste a bit tangier and be lighter in color.

  2. Why do my M&M brownies turn out cakey sometimes?

    This usually happens from overbaking or overmixing the batter once the flour is added. To keep them fudgy, be sure to check for doneness early and fold the flour in gently until just combined.

  3. Can I put M&Ms inside the batter instead of just on top?

    You definitely can! Adding some M&Ms inside the batter will distribute candy colors and flavors throughout, but keep in mind they may bleed slightly while baking, which can tint the batter.

  4. How do I know when M&M brownies are done baking?

    Insert a toothpick about two inches from the edge: you want a few moist crumbs clinging but no wet batter. The edges should look set and slightly pulling away from the pan.

Final Thoughts

I absolutely love how this M&M Brownies Recipe turns out every single time—it’s become a staple for celebrations and casual treats at my house. The best part is how simple it is to make but still feels like a special indulgence. If you’re on the fence, just give it a try—I bet these will quickly become your go-to brownie. Happy baking, friend!

Description

Deliciously fudgy M&M’s brownies featuring a rich chocolate base combined with colorful M&M candies for a fun twist. These brownies are baked to perfection, ensuring a moist and gooey texture that’s perfect for any chocolate lover.


Ingredients

Brownie Batter

  • 1 1/4 cups (285 g) unsalted butter
  • 2 ounces semi-sweet chocolate, chopped
  • 1 1/2 cups (300 g) light brown sugar, packed
  • 3/4 cup (150 g) granulated sugar
  • 4 large eggs, room temperature
  • 1 cup (100 g) Dutch process cocoa powder
  • 1/2 teaspoon salt
  • 3 teaspoons vanilla extract
  • 3/4 cups (95 g) all-purpose flour, spooned and leveled

Topping

  • 2/3 cup M&M chocolate candies


Instructions

  1. Preheat and Prepare the Pan: Preheat your oven to 350°F (175°C). Spray the bottom of an 8 x 8 inch baking pan with non-stick baking spray, then line it with parchment paper. Allow the sides of the parchment to hang over the pan edges by an inch or two for easy brownie removal after baking.
  2. Melt Butter, Chocolate and Sugars: In a heat-safe bowl, combine the unsalted butter, chopped semi-sweet chocolate, light brown sugar, and granulated sugar. Set this bowl over a saucepan filled with 2 inches of simmering water over medium-low heat (double boiler). Stir frequently until the mixture melts and blends into a grainy but glossy consistency. Remove from heat and let it cool slightly.
  3. Add Eggs: Whisk in the eggs one at a time into the chocolate mixture, making sure to fully incorporate each egg before adding the next. Continue whisking until the batter lightens in color and becomes smooth and shiny.
  4. Incorporate Cocoa, Salt and Vanilla: Stir in the Dutch process cocoa powder, salt, and vanilla extract until well combined.
  5. Add Flour: Gently fold in the all-purpose flour with a large spatula, mixing just until a few streaks of flour remain. Avoid overmixing to keep the brownies fudgy.
  6. Fill the Pan and Add Toppings: Spread the batter evenly into the prepared pan. Smooth the top with an offset spatula. Sprinkle M&M chocolate candies evenly over the batter.
  7. Bake: Bake the brownies in the preheated oven for 45 to 50 minutes until the edges are set and a toothpick inserted about two inches from the pan’s edge comes out with a few moist crumbs. Do not overbake to maintain a fudgy texture.
  8. Cool and Slice: Remove the pan from the oven and place it on a wire rack to cool completely before lifting the brownies out using the parchment overhang and slicing into 16 squares.

Notes

  • Using Dutch process cocoa powder gives a deep chocolate flavor and richer color.
  • Room temperature eggs help the batter achieve the right smoothness and volume.
  • Do not overmix the flour into the batter to keep brownies fudgy and moist.
  • Cool brownies completely before slicing to prevent crumbly edges.
  • For thicker brownies, use a smaller pan or increase bake time slightly, checking doneness often.
  • Substitute M&M’s with other chocolate candies or nuts if desired.
