Step 1

Preheat your oven to 350 degrees and prepare a cookie sheet with non-stick cooking spray or parchment paper.

Step 2

In a large bowl, combine dry brownie mix with flour and powdered sugar.

Step 3

Add eggs, vanilla extract, and vegetable oil and mix well until the batter is smooth.

Step 4

Add ¾ cup of M&Ms and combine until well incorporated. Batter will be thick.

Step 5

Roll 2-inch balls of cookie dough and place them at least 2 inches apart on your cookie sheet. Make sure not the flatten the balls of cookie dough, they will flatten as they bake.

Step 6

Bake for 8 minutes in your preheated oven, making sure not to overcook the cookies. You want the centers to be baked completely but still soft for the best results.

Step 7

Remove the cookies from the oven and while still hot, top the cookies with the remaining M&Ms.

Step 8

Let the cookies sit for about 5 minutes before transferring them to a wire cooling rack.

Step 9

Serve warm or at room temperature.
