These Chocolate Peanut Butter Oatmeal bars are our family favorite recipe.  Makes a huge pan that are super chewy and topped with a yummy chocolate and peanut butter frosting swirled together.

  • Yield: 28 1x

Ingredients

Scale
  • 3/4 C margarine….yes, not butter
  • 1/2 C sugar
  • 2 C brown sugar
  • 2 eggs
  • 2 t vanilla
  • 3/4 C creamy peanut butter
  • 3/4 tsp baking soda
  • 1/4 tsp salt
  • 1 1/2 C flour
  • 2 C quick oats

Frosting

  • 12 ounce bag of chocolate chips
  • 1/4 C creamy peanut butter
  • 1 C powdered sugar
  • 2 Tb milk

Instructions

  1. Preheat oven to 325 degrees.  In your mixer, cream margarine and sugars together.  Add eggs and vanilla.  Mix to combine.  Add peanut butter and mix.  Add all dry ingredients and mix until incorporated.
  2. Spread batter into a 13 x 18 inch pan, making sure to get the batter as even as possible across the pan.  Bake for 16-18 minutes on middle rack until golden brown on top.
  3. Remove from the oven and sprinkle with one bag of semi-sweet chocolate chips.  Allow to sit until chocolate melts then spread over the bars.  Mix together the 1/4 C peanut butter, milk and powdered sugar.  Drizzle over the bars and swirl into the chocolate.
  4. Allow bars to cool completely.  You can put them in the refrigerator if the chocolate needs to harden after they have cooled.  I cut off the edges when serving, but that is just my preference.
