Super Easy Peanut Butter & Fluff Bars

This week, my office hosted a bake sale during Walnut Wednesday to support Pelotonia, a bicycle event in Columbus that a few of my coworkers are participating are in (as you know, my lack of bike riding skills make it a little hard for me join) and I was looking for something new to make. I wanted to bake something delicious and unique – but also easy, because I knew  I’d be short on time this week. Betty Crocker’s website offers a variety of cake mix and cookie mix-inspired recipes, and of course I found exactly what I wanted there. I introduce you to, what I’m calling, Easy, Crunchy Peanut Butter & Fluff Bars.

Here’s what you need:

  • 1 pouch (1 lb 1.5 oz) peanut butter cookie mix (I told you it was easy!)

The ingredients – not pictured, the corn syrup. She was shy.

Here’s what you do:

  1. In large bowl, mix peanut butter cookie mix, oil, water and egg until soft dough forms. Press dough in 13×9-inch baking pan prepared with Pam or another cooking spray.
  2. Bake  in a 350 degree preheated oven for 15-17 minutes or until set. Immediately sprinkle marshmallows over crust and bake 2-3 minutes longer or until marshmallows begin to puff.
  3. In a 5-quart saucepan, cook corn syrup, butter, vanilla and chips over low heat, stirring constantly, until chips are melted.
  4.  Remove saucepan from heat; stir in cereal and nuts. Immediately spoon cereal mixture evenly over marshmallows.
  5.  Refrigerate 30 minutes or until firm. When cooled, cut into bars or triangles.
  6. Enjoy!
