Easy M&M Sugar Cookies

Sometimes you just want to bake something simple and fun. That’s when these M&M Sugar Cookie Bars are just the thing. They feature uncomplicated, delicious flavor with a fun and colorful twist.

These soft, sweet cookie bars are certainly not anything fancy, but they are wonderfully delicious and a sure crowd-pleaser. They’re a great option for casual gatherings, homemade gifts, or simply sweet snacking.

As with all cookie bars, the beauty of them versus traditional cookies is that you can skip the scooping and bake the dough in a pan. That’s a lot of prep time you can avoid and still get homemade cookies! Once these cookie bars are baked and cooled, cut them into squares or triangles or whatever shape you like. I usually go with standard squares most of the time, but it’s fun to go with different shapes for some variety.

Have some fun with the M&Ms in these bars! It’s so easy to change the colors for different occasions and seasons. The ones in these photos are a fall color combo that I really love. Use plain, peanut butter, or whatever kind you like best.

When you’re mixing the dough for these cookie bars, save a few M&Ms to sprinkle over the top so you can really show off the fun colors. That’s a good trick for so many recipes that feature add-ins. Just saving a handful to add to the top of the dough before baking will help make sure you get some of those bright colors popping out of the top.

The next time you want a simple baking project that’s easy and fun, give these M&M Sugar Cookie Bars a try. You’ll get a big pan of treats that will disappear quickly and garner plenty of compliments!

M&M Sugar Cookie Bars on a white tray


  • 2 cups (240g) all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 3/4 cup (170g) butter, softened
  • 1/2 cup (100g) granulated sugar
  • 1/2 cup (100g) firmly packed light brown sugar
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 1 cup plain M&Ms


  1. Preheat oven to 350°F. Grease a 9"x 13"x 2" baking pan.
  2. Whisk together the flour, baking powder, and salt. Set aside.
  3. Using an electric mixer on medium speed, beat the butter, sugar, and brown sugar until light and fluffy. Add the eggs, one at a time, mixing well after each addition. Mix in the vanilla.
  4. Reduce mixer speed to low. Gradually add the flour mixture, mixing just until combined. Stir in the M&Ms. (Save 1-2 tablespoons of the candies to sprinkle over the top of the dough if you like.)
  5. Transfer the dough to the prepared pan and spread evenly. If you set aside any candies, sprinkle them over the top of the dough and press down lightly. Bake 20 to 25 minutes, or until the bars are golden brown and a pick inserted into the center comes out clean.
  6. Cool the bars in the pan on a wire rack. Then cut into bars for serving.
