Why This Recipe is Best

This M&M Brownies recipe features double the M&Ms. You fold some in to the the batter, then reserve the rest for sprinkling on top.

  • Uses melted butter in the brownie batter to bake up thick, soft brownies, not cake-y.
  • Melted chocolate AND cocoa powder for rich chocolate flavor.
  • A fudgy consistency.
  • One bowl brownies (or I should say one saucepan)
  • Thick brownies based of my Best Brownie Recipe!

Ingredient Notes

Ingredients needed for M&M's brownies.

M&M’s candies. I used the original milk chocolate M&Ms. Mix up the colors for different occasions and holidays. Or try peanut M&M’s or peanut butter M&M’s for a tasty twist.

Cocoa powder. Make sure it is unsweetened cocoa powder, NOT dutch processed.

Chocolate chips. I prefer the taste of semi-sweet chocolate morsels in brownies. Milk chocolate can be substituted if you prefer.

Vanilla Extract. Pure vanilla extract enhances the chocolate flavor!

Unsalted Butter. I always choose unsalted butter in 99% of my recipes. Brands vary in the amount of salt in salted butter. If you can ONLY use salted butter, skip the extra salt in the recipe.

Easy Instructions

Melt Butter. Start by melting the butter then combining it with granulated sugar and chocolate morsels. Stir until the chocolate is smooth and melted.

Make Batter. Add the eggsto the butter mixture one at a time, then the vanilla extract. Add in the dry ingredients JUST until combined. Fold in half of the M&Ms.

Prepare Pan. Pour the batter into a square baking dish lined with parchment paper and add the rest of the M&Ms on top.

BAKE. Bake for 38 minutes and let cool completely before cutting and serving!

Tips and Tricks

  • Avoid over mixing. Mixing the batter too much or too vigorously will incorporate more air, making the brownies cakey and crumbly. Use large even strokes and stop mixing once you can no longer see the dry ingredients.
  • Line your pan. Put a square of parchment paper at the bottom of your brownie pan for easy removal and clean up.
  • Use a plastic knife for easiest cutting. Make sure the brownies are completely cooled, then slice in long smooth motions.
  • Storing. Store brownies in an airtight container at room temperature. Enjoy within 1 week.

Recipe FAQs

Why do you use melted butter for brownies?

Using melted butter for brownies helps them stay moist, fudgy and chewy. If you use softened butter instead, the action of mixing it in with the sugar will create air pockets making your brownies more similar to a cake.

What kind of pan is best for brownies?

A square baking pan is best for brownies. I use a 9 inch baking pan for this M&M brownie recipe.

Why are my brownies falling apart when I cut them?

Your brownies may be falling apart when you cut them because they aren’t fully cool. Even slightly warm brownies will “tear” when sliced.
Try waiting a few more minutes and using a plastic knife.

Can you freeze M&M brownies?

Yes, these brownies will keep well in the freezer for about 3 months.
