Preheat the oven to 350° Fahrenheit.

In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.

In a large bowl, cream together butter, sugar, and brown sugar until light and fluffy.

Add in Egg and vanilla extract and mix until fully combined.

On a low speed, add in the flour mixture and mix until just incorporated.

Using a wooden spoon, stir in M&M’s. (If prefer to add in 2/3 Cup M&Ms and use the reaming 1/3 to decorate the tops of the cookies before baking)

Roll the dough into 1 to 1 ½ inch balls and place on a lined baking sheet about 2 inches apart from each other.

Bake for 9 – 11 minutes or until the edges of the cookies are lightly browned and set.

Remove the cookies from the baking sheets and allow to cool.

Enjoy!!
