  • 2 cups creamy peanut butter not natural
  • 2 eggs
  • 2 cups granulated sugar
  • 8 ounces marshmallow creme
  • 4 1.5 ounce milk chocolate bars like Hersheys


  • Beat together the peanut butter, eggs, and sugar in a medium mixing bowl. Divide the dough in half and spread one half into a greased 11 x 7 inch baking pan.
  • Spread the marshmallow creme on top of the peanut butter dough and top with the chocolate bars.
  • Spread the remaining half of the peanut butter dough on top and bake at 350 for 22-24 minutes or until set and the edges are lightly browned.
  • Remove from the oven and let cool for 30 minutes. Place in the refrigerator for a few hours until chilled. (this is to set the chocolate again, otherwise it will be gooey). Cut into bars and serve.


To make this recipe in a 9 x 13-inch baking pan, you will need to make the recipe 1 and 1/2 times.
