These peanut butter cup bars have a pretzel crust, a creamy peanut butter filling, and a chocolate shell topping!


For the crust:

  • 2 ounces salted pretzels (I like to use the mini pretzels, not the giant rods)
  • ½ cup all-purpose flour
  • ½ cup brown sugar
  • ¼ teaspoon salt
  • ½ cup unsalted butter, cold

For the filling:

  • 1 cup creamy peanut butter
  • 2 tablespoons unsalted butter, at room temperature
  • ½ cup brown sugar
  • ½ cup powdered sugar

For the topping:

  • ¾ cup semisweet chocolate
  • 3 tablespoons unsalted butter


To prepare the crust:

  1. Preheat the oven to 350 degrees and line an 8” square metal pan with a sheet of aluminum foil.
  2. Pulse the pretzels in a food processor or mini chopper until they are reduced to a coarse sandy mixture. You can leave a few small chunks, if desired. Pulse in the flour, brown sugar, and salt until combined. Add the butter and pulse until small clumps come together. Pat the mixture out into the bottom of the prepared pan and bake in the preheated oven until the shortbread is soft but slightly set, about 20 minutes. Allow to cool briefly while you prepare the filling.

To prepare the filling:

  1. Combine all of the filling ingredients in a medium-sized bowl and mix with a hand mixer until completely smooth. Spread onto the shortbread into an even flat layer and pop in the fridge while you make the topping.

To prepare the topping:

  1. In a double boiler or a medium microwavable bowl, combine the chocolate and butter and heat gently into 20 second increments until melted and smooth. Spread the topping over top of the peanut butter filing and allow to chill till firm. Slice once firm and enjoy!
