Peanut Butter M&M Blondies

Many months ago, I made peanut butter cup blondies.  They were incredible, but also left me wondering about other candy possibilities.  The options seem limitless.  Since Peanut Butter M&Ms rank in my top 5 favorite candies, if not top 3 (after Nutrageous and Peanut Butter Cups, of course), Peanut Butter M&M Blondies were a logical progression.

Let’s just say the experiment was a success.  I used a generous helping of M&Ms instead of peanut butter cups.  I also used peanut butter chips to boost the peanut buttery goodness.  The result was dangerous.  Lots of tasty M&Ms in every bite, lots of good peanut butter flavor…yet they still come in around 210 calories.  Gotta love it!

  10. Tried your recipe. The blondie turned out with a hard top layer but the inside was still chewy. It was more like a cookie than a cake! I did not put in peanut butter cups and the peanut buttery taste was more than enough.
