Cookie Bar

  • 1 cup butter room temperature
  • 1 cup granulated sugar
  • 1/2 cup creamy peanut butter
  • 2 eggs
  • 4 tsp vanilla
  • 2 tsp baking powder
  • 3 tsp salt
  • 3 cup flour
  • 1 cup chocolate chips

Chocolate Frosting

  • 1/2 cup milk
  • 1/2 cup butter
  • 1 1/3 cup granulated sugar
  • 2 tsp vanilla
  • 1 cup semi-sweet chocolate chips
  • 1/2 cup creamy peanut butter


  • Preheat oven to 350°. Line a cookie sheet with parchment paper, or spray with non stick spray.
  • Cream the butter and sugar together for 3 minutes. It will become light and fluffy. Scrape down the sides and mix in the peanut butter, eggs and vanilla until well incorporated.
  • Add the flour, baking powder and salt. (I usually toss it all in at once and mix slowly) Mix until just combined. Stir in the chocolate chips.
  • Press the dough into the bottom of a parchment paper lined cookie sheet. (21"x15") Bake at 350° for 10-12 minutes, or until the center is puffy and is no longer glossy. You'll want to pull them before they start to brown.
  • Once the cookies have cooled, combine the milk, butter and sugar in a sauce pan. Bring it to a rolling boil and boil for 45 seconds. Take off of the heat and stir in the vanilla, chocolate chips and peanut butter. Pour over the sheet of cookies immediately.
  • Let the frosting cool and dry completely before cutting. Cut, drool, eat and repeat!


This recipe makes a large batch of 32 cookie bars. Feel free to halve the recipe if needed. 
I use a mixture of mini semi-sweet chocolate chips and large milk chocolate baking chips. You can use whatever you have on hand.
