Oatmeal Layer

  • 3 cups brown sugar
  • 1 cup butter {softened}
  • 1/2 cup creamy peanut butter
  • 2 tsp vanilla extract
  • 3 eggs
  • 2 tsp baking powder
  • 1 tsp salt
  • 3 1/2 cups quick oats
  • 3 1/4 cups all purpose flour
  • 1/2 cup mini M&M's
  • 1/2 cup mini chocolate chips
  • 1/2 cup peanut butter chips

Fudge Layer

  • 14 oz can sweetened condensed milk
  • 12 oz semi-sweet chocolate chips
  • 3 tbsp butter


  • Preheat oven to 350° and spray a 9x13 inch baking dish with non-stick spray.
  • Combine brown sugar, butter, peanut butter and vanilla extract in an electric mixer. Beat on medium speed to cream mixture until it is light and fluffy.
  • Next add the eggs, baking powder and salt on low speed. Slowly add the flour and oats, mix until just combined {don't over mix}. Add M&M's, mini chocolate chips and peanut butter chip, mix in by hand or on low speed of the mixer. Add 60% of the dough to the pan and press into the bottom of baking dish {being sure it is in an even layer}.
  • For the fudge layer, combine the chocolate chips, sweetened condensed milk and butter in a microwave safe bowl. Microwave for 2 minutes, mix and add 30 second intervals until the mixture is smooth. Pour the fudge over the bottom oatmeal layer.
  • Take the remaining dough and crumble pieces over the entire surface of the fudge. Bake for 30-35 minutes, or until the top is golden brown. Cool completely at room temperature and chill for at least 60 minutes before cutting into squares. Store at room temperature for up to 5 days.
