Peanut Butter M&M Blondies

Sometimes I just want peanut butter and M&M’s (okay – not sometimes… I want them everyday). I decided to make something fast and easy so I could have these two amazing ingredients together. I served some right out of the oven with some ice cream on top. With the rest, I let them cool and then ate them the next day!

  1. Disappointed in this recipe. I am a good baker and mine I did in an 8x8 Pyrex pan, lined with foil and after 40 minutes of baking took them out because my toothpick came out clean, cut them and the very outer edges crumble and the rest seems underbaked. Is this how a blonde should be?
    • We use store brand (Kroger) and name brand peanut butter in this recipe. They all work the same. We usually buy Jif or Skippy when buying the store brand. We haven't used natural peanut butter in this recipe, so we aren't sure how the outcome would be with that.
