Why You’ll Love These Fudgy M&M Brownies

There’s something universally comforting about brownies, but this version takes things up a notch. The batter is intentionally rich and thick, creating brownies that stay moist for days. The M&Ms don’t just sit on top — they melt slightly into the surface, forming pockets of chocolate and candy crunch that make each square exciting.

These brownies are:

Deeply chocolatey without being overly sweet
Fudgy rather than cakey
Quick to prepare with no mixer required
Easy to customize with different candy colors or mix-ins
Perfect for holidays, parties, or everyday treats

They’re also incredibly forgiving. Even if you slightly overbake them, the brownie texture remains soft and chewy thanks to the high butter and chocolate content.

Ingredients

Use fresh, high-quality ingredients for the best flavor and texture.

Unsalted butter
Granulated sugar
Brown sugar
Large eggs
Vanilla extract
Unsweetened cocoa powder
All-purpose flour
Salt
Semi-sweet chocolate chips
M&M candies

Each ingredient plays a role: butter provides richness, cocoa powder deepens the chocolate flavor, and the combination of sugars creates that signature chewy-fudgy texture.

Instructions

Preheat your oven to 350°F (175°C) and line a square baking pan with parchment paper, leaving an overhang for easy removal.
Melt the butter gently and allow it to cool slightly.
In a large bowl, whisk together the melted butter, granulated sugar, and brown sugar until glossy and smooth.
Add the eggs one at a time, whisking well after each addition. Stir in the vanilla extract.
Sift in the cocoa powder, flour, and salt. Fold gently until just combined — do not overmix.
Fold in chocolate chips, reserving a small handful for the top.
Pour the thick batter into the prepared pan and spread evenly.
Sprinkle M&M candies and reserved chocolate chips evenly over the surface.
Bake for 25–30 minutes, until the edges are set and the center is slightly soft.
Allow brownies to cool completely in the pan before lifting out and slicing.

Pro Tips for Perfectly Fudgy Brownies

Don’t overbake: The center should look slightly underdone when you remove the pan from the oven. Brownies continue to set as they cool.
Use parchment paper: This makes clean slicing and removal much easier.
Cool completely before cutting: This ensures neat, bakery-style squares.
Use room-temperature eggs: They blend more smoothly into the batter.

Fun Variations

Swap classic M&Ms for peanut, caramel, or holiday-colored M&Ms.
Add chopped walnuts or pecans for crunch.
Swirl in peanut butter or caramel sauce before baking.
Sprinkle flaky sea salt on top for a sweet-salty finish.

Serving Suggestions

Serve these brownies slightly warm with vanilla ice cream, drizzle with chocolate sauce, or dust with powdered sugar. They’re also fantastic wrapped individually for bake sales or packed into lunchboxes as a sweet surprise.

Storage and Make-Ahead Tips

Store brownies in an airtight container at room temperature for up to 4 days. For longer storage, freeze individual squares for up to 2 months. Thaw at room temperature or warm gently before serving.

A Little Brownie History

Brownies originated in the United States in the late 19th century and quickly became a staple dessert. Adding candies like M&Ms is a modern twist that brings playful color and texture, making brownies even more irresistible for kids and adults alike.
