How To Make Mint M&M Brownie Cookies

Let's get these Mint M&M Brownie Cookies baking! Preheat the oven to 350º.

In a separate bowl, whisk together the melted butter and sugar until they're well combined. Then, add in the egg, vanilla, and peppermint extract – give it a good stir.

Grab a cookie scoop or tablespoon and scoop the cookie batter onto a parchment-lined baking sheet, about 2 inches apart. To make them festive, press some green M&Ms on top. 

Now, into the oven they go for 10 minutes. Keep an eye on them – we want them mostly set but a tad soft in the middle.

Once they're out, let them cool on the baking sheet. And there you have it – Peppermint Brownie Cookies ready to be enjoyed!

Brownie Variations

  • Add chocolate chips. Stir in a half cup of chocolate chips into the batter for extra gooey goodness.
  • Add nuts. Add a crunch by folding in chopped nuts like walnuts or pecans. About half a cup should do the trick.
  • Kick up the mint flavor. Use mint flavored M&M's for a more minty flavor.

Make-Ahead, Storing and Freezing

Make Ahead: To prepare these brownie cookies, you can prepare the dough in advance and refrigerate it. Make sure it is tightly covered to prevent drying. When ready to bake, allow the dough to come to room temperature before scooping and baking as directed.

Store: To store leftover cookies, place them in an airtight container at room temperature for up to 3 days. To maintain freshness, consider adding a slice of bread to the container, as it helps prevent the cookies from becoming too dry.

Freeze: If you want to freeze the cookies, ensure they are fully cooled before placing them in a freezer-safe container or Ziploc freezer bag. For optimal freshness, separate layers with parchment paper. When ready to enjoy, thaw the cookies at room temperature or warm them in a low-temperature oven.

Recipe Tips

  • When combining wet and dry ingredients, mix just until everything is incorporated. Overmixing can result in tougher cookies.
  • Use a small cookie scoop or Tablespoon for scooping cookie dough to ensure even baking. This helps all the cookies cook at the same rate.
  • Keep an eye on the cookies in the last few minutes of baking. They should be mostly set but slightly underdone in the middle. Oven temperatures may vary, so adjust accordingly.
  • Let the cookies cool on the baking sheet for a few minutes before transferring them. This helps them set up properly.

Recipe FAQs

Is there a difference between peppermint and mint extract?

Peppermint extract has a more intense and specific flavor compared to general mint extract, which may include spearmint or other milder mint flavors.

Can I skip the peppermint extract altogether?

Yes, if you're not a fan of mint, you can omit the peppermint extract. The cookies will still have a rich chocolate flavor. You can add a little mint flavor by using mint flavored M&M's instead.
