These are the easiest Fudgy Crinkle Top M&M Brownies. Every bite is rich and decadent, extra chocolatey, perfectly chewy, and oh so fudgy. Made with only a handful of ingredients: flour, sugar, eggs, vanilla, salt, butter, bittersweet chocolate, and (of course!) lots of M&M’s! Truly the perfect treat for any chocolate lover.

We’ve tweaked our classic brownie to give you a dessert that’s better than any other. First, we added more chocolate because, well, the more chocolate, the better! We also included an extra egg for added richness and decadence. And finally, we mixed in a whole bag (10 oz) of M&M’s.

The result? Every bite is a perfect combination of chewy, fudgy, crunchy, and not too sweet. Just like our chocolate brownie cookies, these brownies are easy to mix up with just a few ingredients, a whisk, and a pan. Minimal prep, maximum deliciousness! Perfect for any occasion.

Ingredients

Full ingredient amounts and instructions can be found in the recipe card at the bottom of the post.

  • Bittersweet Chocolate – Ours is 60% cocoa which makes these brownies rich, decadent, and delicious.
  • Salted Butter – Using melted butter creates the rich and fudgy texture that equals the perfect brownie every time.
  • Large Eggs – add richness and moisture, as well as acting as a binder and giving these brownies a bit of lift.
  • Granulated Sugar – perfectly sweetens these brownies.
  • Vanilla Extract – rounds off the flavor in these brownies and really makes them taste SO GOOD!

How To Make M&M Brownies (Step-by-Step!)

Step 1: Prepare batter

Combine chocolate and butter in a microwave safe bowl. Heat in 15 second increments, stirring after each, until melted and smooth. Set aside.

In a large bowl, whisk together eggs, sugar, salt, and vanilla.

Whisk in chocolate mixture.

Stir in flour.

Fold in M&M’s.

Step 2: Bake

Pour into pan and spread evenly. Bake for 30-35 minutes, or to desired degree of doneness.

How To Tell When Brownies Are Perfectly Baked

We found that, with these brownies in particular, using a cake tester or tooth pick is the best way to tell when they’re perfectly baked. After inserting the cake tester, it should still be a little damp with maybe one or two crumbs on it.

This means that the brownies are still fudge-y and moist, while being just barely baked!

Mix-In Ideas

Looking to spice things up a bit? Here are a few additions to add to your brownies to make them even MORE delicious!

  • Add nuts! It’s a super simple way to add flavor and texture. Walnuts, pecans, or peanuts make a delicious addition to these brownies.
  • Caramel pieces/chunks can add gooey goodness to these brownies.
  • Chopped Oreos
  • Peppermint Pieces
  • Chopped Candies (Snickers or Twix are our favs!)
  • Shredded Coconut

How To Store

Since these brownies are so moist, it’s best to keep them in a zip-top bag or airtight container and in the fridge for 5-7 days. You can also store them in the freezer in a freezer safe bag for up to 2 months!
