Why You Should Make these Cookies

  • These are perfect for leftover Halloween candy!!
  • They’re not as messy as brownies so perfect for lunchboxes and snacks.
  • You can swapp out the M&Ms for any seasonal version to make holiday cookies!

We get oodles of trick or treaters at our door. I love to buy a variety of full-sized candy bars…and when my kids were little, I let them select one for themselves before the doorbell started ringing. Katie and Tom would choose Reese’s Peanut Butter Cups and Nick was more likely to pick Skittles.

The hubby, my 4th kid, liked to confiscate some M&M’s or 3 Musketeers Bars. And I liked to set aside some of the candy that works well in cookies, and here’s where I reach for the M&M’s, too.

Frequently Asked Questions

Why Is My Cookie Dough Loose and Runny?

This happens when the butter and chocolate are still too warm. Let the dough rest until it’s thick enough to scoop out nice mounds of dough with a cookie disher.

What Can I Use Instead of M&Ms?

The original recipe used semisweet chocolate chips, so that’s an easy alternative. White chocolate, bittersweet chocolate, mint chips, etc. will also work well.

How Do I Make Nice Round Cookies?

I have a few tips:

  • Hold back some of the M&Ms as too many will make it hard to get nice dough balls.
  • Use a cookie disher for even sized cookies.
  • With a damp finger, gently tap the dough mounds so they are nicely rounded.
  • After the cookies come out of the oven, while hot and pliable, use your spatula to tap the baked cookies into nice rounds. If the cookies are sticking to the spatula, spray it with a non-stick cooking spray like Pam

What to Do with Leftover Halloween Candy

At Easter, the white chocolate egg-shaped M&M’s go into brown butter M&M cookies, but at Halloween, I think brownie cookies dotted with classic M&M’s are perfect for my own goblins. A combination of white and dark chocolate chips works well in these brownies in cookie form, too. No matter which option you chose, these M&M Brownie Cookies will definitely be a crowd-pleaser. These chewy Classic M & M Cookies are also winners!

Tip of the Day: When making M&M cookies, reserve a few to add to the top of the cookies immediately after they come out of the oven for a prettier presentation.
