Ingredients
  

Base Ingredients
  • 1 roll peanut butter cookie dough (about 16.5 ounces)
  • 1 jar marshmallow creme (7 ounces)
  • 1/2 cup creamy peanut butter Warm slightly for easier drizzling.

Method
 

Preparation
  1. Preheat the oven to 350 degrees F and lightly grease an 8×8-inch glass baking dish.
  2. Press the peanut butter cookie dough evenly into the bottom of the prepared dish to form the crust.
Baking
  1. Bake for 12 to 15 minutes, until the cookie base is puffed and lightly golden around the edges.
Assembling
  1. Spoon the marshmallow creme over the hot crust and gently spread it as evenly as you can.
  2. Warm the peanut butter just enough to loosen it, then drizzle it over the marshmallow layer.
Cooling and Serving
  1. Let the bars cool completely before cutting into squares and serving.

Notes

These bars are best served chilled or at room temperature. Store any leftovers in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week.
