Peanut Butter Bars

I think everyone can agree that one of their best memories from elementary school was the peanut butter fingers also known as lunch lady peanut butter bars!! They seriously made your day at school the best! This recipe is the closet that I have been able to get to it, and I think its pretty dang close. It has a soft oatmeal layer followed by a creamy smooth peanut butter, and a fabulous chocolate layer.

  • 1 ¼ Cups Margarine 3/4 for the crust, and 1/2 for the frosting
  • 3/4 Cup Brown Sugar
  • 1/2 Cup White Sugar
  • 2 Eggs
  • Cup Peanut Butter ¾ for the crust and 1½ for the peanut butter layer.
  • Cups Flour
  • 3/4 Tsp. Salt 1/2 for the crust, and 1/4 for the frosting
  • 1/2 Tsp. Baking Soda
  • Cups Quick Oats
  • 2 Cups Powder Sugar
  • 1/2 Tsp. Vanilla
  • 3 Tbsp. Coco Powder


  • Preheat oven to 350°
  • Start by mixing ¾ cup softened margarine, ¾ cup brown sugar and ½ cup white sugar together until creamy.
  • Next, you will add 2 eggs, and ¾ cup peanut butter. I usually use creamy peanut butter, but chunky is really good in peanut butter bars also. I love the little crunch that the chunky peanut butter adds.
  • Finally, add ½ tsp. baking soda, ½ tsp. salt, 1¾ cups of flour, and 2½ cups of quick oats. Mix well.
  • Spray sheet plan lightly with cooking spray. Firmly press mixture into the bottom of the pan.
  • For this last step I like to use a rolling pin, and a piece of parchment paper. Rolling the crust out will help even out any lumps and it will help produce and smoother prettier peanut butter bar. I use the parchment paper to help keep anything from sticking.
  • Now, bake for 8-10 mins. or until slightly golden brown.
  • While the crust is baking lets start the peanut butter layer. To whip the peanut butter use a wire whisk and whip 1½ cups of peanut butter for a couple min.
  • Spread the peanut butter on the bars while still warm. Set aside
  • Now let start the frosting. Using a wire whisk attachment mix together ½ cup softened margarine, ½ tsp. vanilla, ¼ tsp. salt and 3 tbsp. of coco powder.
  • Next, slowly add in 2 cups of powder sugar. If the consistency is to thick add in a little warm water at a time until you have the desired consistency.
  • Finally, frost and enjoy!
