Using Other Nut Butters

People often ask if you can make these with other nut butters.  Yes, of course!  I mean, then they’ll be almond butter bars or cashew butter bars, but yes of course.  

Just make sure to mix the nut butter really, really well first if it’s the ‘natural’ kind that require stirring — and if the mixture feels too ‘greasy’ add an extra 1/2 to 1 cup of powdered sugar.

The world is your oyster when it comes to peanut butter bars!

Tips and Tricks for The Best No Bake Peanut Butter Bars

  1. Not into peanut butter?  You can substitute in any other nut butter — almond butter, cashew butter, etc – or a combination of nut butters.
  2. This works best with conventional (not the natural kind that separates) peanut butter.  If you are using a natural nut butter, stir the nut butter extremely well and add 1/2 cup of additional confectioners’ sugar to offset the oily texture of natural nut butters.
  3. Grind the graham cracker crumbs well.  You can use a food processor or break the graham crackers by hand with a heavy object (like a rolling pin), but make sure the graham crackers crumbs are small and consistent; no big pieces.
  4. When storing peanut butter bars, place a sheet of wax paper in between layers so the peanut butter from the bottom doesn’t stick to the chocolate on top of the bar beneath it.
  5. Peanut butter bars can be stored at room temperature or refrigerated to keep the chocolate on top from melting, or frozen for up to 3 months.

Perfect for football parties, birthday parties, holiday parties, dinner parties, or any kind of party.  An after school treat, a sleepover, or just because it’s Tuesday and you want an easy, fun dessert.
