About This Recipe

I am always trying to think up new recipes for bar cookies.

Face it, if you want to make something sweet in just a few minutes that will feed a crowd, bar cookies are the way to go. You don’t have to futz around with shaping individual cookies, you can bake the recipe in one fell swoop instead of baking batches and batches, and these recipes can be modified in hundreds of different ways.

My favorite topping for bar cookies is a combination of melted semisweet chocolate chips and peanut butter. This recipe uses that mixture as one layer in a three layer bar. The bottom is a rich peanut butter cookie, and the top is a fluffy peanut butter frosting.

This bar is incredibly indulgent, with the perfect combination of textures and flavors. And there’s peanut butter in all three layers!

Enjoy this recipe; you’ll make it often during the school year.



Preheat the oven to 350°F. Spray a 9" x 13" pan with nonstick baking spray containing flour.


In a large bowl, combine 1/3 cup butter, 1/3 cup peanut butter, 1/3 cup brown sugar, 1/3 cup granulated sugar, and 1/3 cup powdered sugar. Beat well to combine then beat in the egg.


Stir in flour and baking powder until a dough forms. Press into the bottom of the prepared pan.


Bake for 12 to 18 minutes or until the layer is just set. Don't overtake. Let cool for 10 minutes while you prepare the next layer.


In a medium microwave-safe bowl, combine the semisweet chocolate chips, milk chocolate chips, and 2/3 cup peanut butter. Microwave on high for 1 minute intervals, stirring after each interval, until the mixture is melted and smooth. Pour over the baked layer and spread to cover. Cool.


When the chocolate layer has cooled (you can put it in the fridge to speed up this step), combine 1/2 cup butter and 1 cup peanut butter in a medium bowl and beat well.


Add the 3-1/2 cups powdered sugar and milk alternately until the frosting is smooth and fluffy. Beat in the vanilla.


Spread the frosting over the chocolate layer. Then combine the mini chips with the chopped peanuts and sprinkle over the bar. You're done! Store covered at room temperature.
