Ingredients

Oatmeal Cookie Bar:

  • 3/4 cup unsalted butter melted
  • 3/4 cup brown sugar packed
  • 1 Tablespoon pure vanilla extract
  • 1 cup all-purpose flour to make this gluten free, you can use finely ground GF oat flour like Bob's Red Mill
  • 1 cup rolled old fashioned oats
  • 1 teaspoon baking soda
  • 1/8 teaspoon salt

Peanut Butter Layer:

Chocolate Layer:

  • 1-1/2 cups chocolate chips
  • 3 tablespoons heavy cream or vegetable shortening

Instructions

  1. Preheat oven to 350 degrees F. Line an 8x8 square pan with parchment paper or foil sprayed lightly with cooking spray; set aside.

  2. In a large microwave-safe mixing bowl, add the butter and heat on high power to melt for about 90 seconds. Whisk in the brown sugar and vanilla until smooth.
  3. Add the flour, oats, baking soda, salt, and stir with wooden spoon or spatula until just combined. Do not over-mix.
  4. Add mixture to the prepared pan and smooth it with a spatula or the back of a spoon, to create an even, smooth, flat layer.
  5. Bake for 21 to 24 minutes, or until edges are golden. Set aside to cool.
  6. Meanwhile make the filling by beating peanut butter, powdered sugar, and vanilla together until smooth. Spread filling evenly over cooled crust. Smooth the top with offset spatula. Chill for about 30 minutes.
  7. In a medium microwave bowl, microwave chocolate chips and cream or shortening on high power in 15-second increments, stopping and stirring frequently until smooth. Do not overheat. Pour chocolate layer over peanut butter and shake the pan a bit to help chocolate slide and disperse. Then smooth it very lightly with an offset spatula, knife, or offset knife.
  8. Chill until chocolate is set before cutting and serving.
