  • Prep oven and baking sheets. Preheat oven to 350 degrees F. Line two baking sheets with parchment paper or spray with nonstick cooking spray.

tips and tricks

Here are some helpful tips for this recipe!

  • You can use a measuring spoon if you don’t have one. cookie scoop. I like to dip the spoon before adding the marshmallow creme for easy removal.
  • Make sure your butter is at room temperature.
  • Instead of marshmallow cream, you can use mini marshmallows. I have tried both versions. The mini marshmallows were good, but I definitely liked the consistency better using the marshmallow fluff.
  • If your dough gets too hot, place it in the fridge before dividing into balls.
  • For a fun twist, substitute the peanut butter chips for the chocolate chips.
  • Not a fan of marshmallows? Feel free to skip the marshmallows altogether and enjoy them as thin, chewy, and soft peanut butter cookies.
