Can I freeze peanut butter blondies?

Yes, peanut butter blondies freeze very well. To freeze, simply wrap in foil and place in an airtight container or freezer bag. The blondie dessert will keep in the freezer for up to 3 months.

Quick tips for peanut butter blondies

  • Line your baking dish with foil for easy removal.
  • For extra peanut butter flavor, use peanut butter chips instead of chocolate chips.
  • Place extra M&M’s on top prior to baking. This makes them look extra pretty. :)
  • Use festive M&M’s around the holidays, like Valentine’s, Easter, Halloween and Christmas.
  • Don’t overcook! They may look a little soft, but they’ll harden as they cool.
  • Use a toothpick to make sure the center of your peanut butter blondies comes out clean.

  • Preheat oven to 325°F and grease a 9×13" pan. Lightly dust with flour or line with foil. 
  • Cream butter and sugar in a large bowl. Add in eggs and vanilla and stir until combined. In a separate bowl, whisk together the flour, baking powder and salt. Pour into the butter mixture and stir. Fold in chocolate chips and M&M’s.
  • Press 1/2 the dough into the pan with flour on your hands. Cut the Reese’s into small pieces and lay them on top of the dough. Place the remaining cookie dough on top of the Reese’s. You can add extra M&M’s on top if you’d like. 
  • Bake for 30-40 minutes or until lightly browned. Oven temps will vary. Test with a tooth pick. The dough should be soft in the center.
  • Allow bars to cool and then enjoy with a cold glass of milk!


Alternatively you could use reeses pieces instead of peanut butter m&m’s.
