Reese’s Peanut Butter Bars

Reese’s Candy Pie grabbed my attention for two reasons–Reese’s candy and pie. Now that is my kind of dessert! I love Reese’s Peanut Butter Cups, so any recipe that includes a chocolate and peanut butter balance works for me and my sweet tooth! And you don’t have to be intimidated by the pie piece (see what I did there?). This is a pie that anyone can make!

Reese’s Peanut Butter Bars Crust

It starts with the peanut butter cookie crust for this dessert. Yes, those are the only three ingredients you need to make my 3 Ingredient Peanut Butter Cookies. It also just happens to be perfect as a crust for this Reese’s Candy Pie! So, to make the crust, combine the peanut butter, sugar, and egg in a medium bowl. Pour this into a greased 8×8-inch pan. Bake the crust for 10-15 minutes and let it cool completely before you add the topping.

  1. Hi. Do you think an artificial sweetener like swerve might work? I would also make my own whipped cream with swerve. I was wondering how this would turn out. Thank you so much…sounds like an amazing recipe🙂

    1. Hi, Patty! I work with iambaker and am happy to help with questions. We have not tested this recipe with substitutions, so I can’t say how it would affect the dessert. Let us know if you try it and how it turns out. Have a great day!
