Equipment

Ingredients

  • ¾ cup butter, softened
  • ¾ cup granulated sugar
  • ¾ cup packed brown sugar
  • 2 large eggs
  • 1½ teaspoons vanilla extract
  • 2¼ cups plus 2 tablespoons all-purpose flour

How to Make Halloween M&M Cookies

Step One: Make The Dough

Beat the softened butter with both sugars until light and fluffy – about 3-5 minutes. Add the eggs and vanilla, and mix until combined. Whisk the flour, baking soda, and salt together in a separate bowl. Then, add the dry ingredients to the butter mixture one cup at a time, mixing at low speed.

Step Two: Chill

Cover the dough in the bowl and put it in the fridge for 1 hour.

Step Three: Shape

Preheat your oven to 350°F and line baking sheets with parchment paper.

Drop tablespoon-sized balls of dough onto the baking sheets, about 2 inches apart. Press 3 extra M&Ms on top of each cookie – one of each color looks nice.

Step Four: Bake

Bake for 11-13 minutes until edges are lightly golden. Let them cool on the baking sheet for 5 minutes before moving them to a cooling rack to cool completely.

Serving & Storing

These M&M cookies are best served with milk, hot chocolate, vanilla ice cream, coffee, tea, or apple juice.

Keep the cookies in an airtight container at room temperature for up to 1 week.

To freeze baked cookies, lay them in a single layer on a baking sheet, freeze, then place them in an airtight container or freezer bag for up to 3 months.

To freeze the cookie dough, shape it into balls on a baking sheet, freeze, then place the dough balls in a freezer bag for up to 3 months. When you’re ready to bake, place the frozen dough balls on a baking sheet and bake as directed, adding 1-2 minutes to the baking time.

Answering Your Questions

Can I skip the chilling step if I’m in a hurry?

Nope – the chilling prevents the cookies from spreading too much and keeps them thick. If you’re really pressed for time, 30 minutes is the absolute minimum.

Can I use mini M&Ms instead?

Sure, but use about 1¾ cups since they’re smaller. The regular size gives better color pop though.

My dough seems too sticky to work with….what happened?

Your butter might be over-softened or your kitchen is too warm. Pop the dough back in the fridge for another 15-20 minutes.

Instructions

  • Cream butter and sugar. Beat the softened butter, granulated sugar, and brown sugar with an electric mixer on medium speed until light and fluffy, about 3-5 minutes. Then, add the eggs and vanilla extract and blend until combined, scraping down the sides of the bowl as needed.
  • Mix dry ingredients. Whisk together the all-purpose flour, baking soda, and salt in a separate mixing bowl.
  • Combine. Gradually add the dry ingredients to the butter mixture, mixing at low speed, one cup at a time, until combined. Then, stir in 1½ cups of the Halloween-themed M&Ms by hand.
  • Chill. Cover the dough and chill it in the refrigerator for 1 hour.
  • Prep. Towards the end of the chilling time, preheat the oven to 350°F (175°C) and position the oven rack in the center. Prepare two baking sheets with parchment paper or lightly coat them with cooking spray.
  • Shape. Drop the dough by tablespoon-sized balls onto the prepared baking sheets, spacing them about 2 inches apart. Press 3 additional M&Ms on top of each dough ball for decoration (try to get one of each color).
  • Bake. Bake at 350°F (175°C) for 11-13 minutes or until the edges are lightly golden. Allow the cookies to cool on the baking sheets for 5 minutes before transferring them to a wire cooling rack to cool completely.

Notes

You don’t have to press M&Ms on top, but it makes the cookies look much nicer.  Choose one of each color for the best look.
