5 Minute Oreo Marshmallow Bars You Have To Try!


Units Scale
  • 56 Oreo cookies, crushed
  • 2 tbsp Butter
  • 4 1/2 cups Mini Marshmallows


  1. Crush all the Oreo cookies into pieces. I used a gallon sized plastic bag and a rolling pin to break them.
  2. Combine the mini marshmallows and butter in a bowl. Microwave in 30 second intervals until the marshmallows have lost their shape and the butter is fully melted.
  3. Add the cookie pieces to the marshmallow mixture and stir well. Scrape the mixture into a parchment paper lined baking pan. Allow to harden before serving. (If you don’t want to use parchment paper, you HAVE to grease the pan. Otherwise the dessert will stick to the pan and be impossible to remove.)
