  • 1/2 cup butter softened (1 stick)
  • 1 cup sugar
  • 1 cup brown sugar
  • 3 eggs
  • 2 cups creamy peanut butter
  • 1 tsp. vanilla
  • 2 tsp. baking soda
  • 4 cups old-fashioned oats
  • 3/4 cup semi-sweet chocolate chips
  • 3/4 cup M&M's chocolate candies
  • 3/4 cup raisins


  • Preheat oven to 350 degrees F. Line a large baking sheet with parchment paper and set aside.
  • In a large bowl, mix together the butter and sugars until creamy. Add the eggs, peanut butter and vanilla and mix well. Stir in the baking soda and oats. Stir in the chocolate chips, M&M candies and raisins. Mix well.
  • Using a 1/4 cup measuring cup, drop batter onto prepared baking sheet. Slightly flatten each round of batter with your fingers, creating a circle with a 3-inch diameter. Top with extra M&Ms, if desired.
  • Bake in the preheated oven for 15-19 minutes, or until edges are golden brown and centers are no longer doughy. Let cool and store in a sealed container.
