Ingredients

Peanut Butter Oatmeal Cookie Bar

  • 1/2 cup softened butter
  • 1/2 cup brown sugar
  • 1/2 cup granulated sugar
  • 1 cup all purpose flour
  • 1 cup oatmeal quick oats or regular, both turn out great
  • 1 egg
  • 1/3 cup peanut butter creamy or crunchy
  • 1/4 tsp. salt
  • 1/2 tsp. baking soda
  • 1/2 tsp. vanilla

Chocolate Topping

  • 1 cup chocolate chips

Peanut Butter Icing

  • 1/2 cup powdered sugar
  • 1/4 cup peanut butter
  • 2 Tbs. milk

Instructions

  • In a large bowl, cream together the butter, brown sugar and granulated sugar.
  • In the same bowl, blend into the butter and sugar mixture the egg, peanut butter, salt, baking soda, and vanilla.
  • Into the wet ingredients, add the flour and oatmeal and mix until there is no more visible flour.
  • Lightly grease a 9x13 baking dish before spreading the cookie mixture into the pan.
  • Bake at 350 for 20-25 minutes or until the edges are golden brown and a toothpick poked in the center comes out clean.
  • Evenly sprinkle 1 cup of chocolate chips over the pan of cookie bars. Once it is melted, spread the chocolate over the surface.
  • Let the cookies cool 10 minutes while you prepare the peqnut butter icing. In a small bowl, mix together with a whisk the powdered sugar, 1/4 cup of peanut butter and milk. Pour the mixture over the top of the chocolate covered cookie bars and use a spatula to gently swirl the icing on top of the chocolate.
  • Eat right away if you can't wait, or let them cool completely for easy cutting!

Notes

  • The original recipe calls for quick oatmeal, however, I've used regular oats for years and it still tastes great! 
  • Creamy or crunchy peanut butter should work for this recipe. I typically use natural peanut butter without stabilizers like Adam's. If you use peanut butter with palm oil or a stabilizer, then the cookie dough will be stiffer, but should bake just fine.
