Peanut Butter Bars

  • 1 cup (2 sticks) salted butter melted
  • 2 cups graham cracker crumbs
  • cups powdered sugar
  • 1 cup creamy peanut butter not all-natural
  • 1/4 cup brown sugar
  • 3/4 cup mini Reese's Pieces


  • cups milk chocolate chips
  • 2 tablespoons creamy peanut butter
  • 1/2 cup mini Reese's Pieces


  • Prepare a 9x13 baking dish by lining with parchment paper or tin foil. This makes the bars much easier to lift out so you can cut them.
  • In a large mixing bowl with a handheld mixer, or use the bowl of a stand mixer, add the melted butter, graham cracker crumbs, powdered sugar, peanut butter, and brown sugar. Blend together until it's combined well.
  • Stir in the mini Reese's Pieces candy.
  • Press the dough into the prepared pan. It helps if you drop spoonfuls of dough all over the pan, instead of just one big pile in the middle, and then spread it out.
    * I like to use the back of a silverware spoon to help spread. If it's getting too sticky lightly spray your fingers or the back of a spoon with cooking spray.
  • Add the milk chocolate chips and peanut butter into a microwave-safe bowl. Cook for 1 minute and stir. Cook for another 1 minute. Stir again.
  • Pour the peanut butter chocolate over the bars and spread out evenly. Sprinkle more mini Reese's Pieces over top and gently press them into the chocolate.
  • Cover the pan with tin foil and refrigerate for at least 3 hours before serving and cutting.
  • Leftovers need to be stored in the fridge. As these bars sit at room temperature they will soften up and the chocolate topping will begin to soften and melt slightly.


Reese's Pieces : These can actually be hard to find. They used to sell them by the chocolate chips but not anymore! I can usually find them by the ice cream toppings. You know in the frozen ice cream aisle they usually have a place for syrups and toppings? Well, I always find mini Reese's Pieces there. If you can't find the minis then go ahead and use regular Reese's Pieces. Either use them whole or I like to chop them up into smaller pieces. 
I also like to use some mini Reese's Peanut Butter Cups that I chop in half. 
A little piece of these bars goes a long way! Don't cut them too big.
