  • 1/2 cup butter, softened
  • 3/4 cup sugar
  • 3/4 cup packed brown sugar

  • 1-3/4 cups plain M&M's, divided


  1. Preheat oven to 350°. In a large bowl, cream butter, sugars and vanilla until light and fluffy, 5-7 minutes. Beat in eggs, 1 at a time. Whisk together the flour, baking powder and salt; gradually add to the creamed mixture. Stir in baking chips and 1 cup M&M's.
