No Bake Oreo Bars Ingredients

No Bake Oreo Marshmallow Bars


  • 1 package Oreo Cookies (approx 14 ounces)
  • 4 tbsp butter
  • 10 oz. mini marshmallows
  • 4 oz. white chocolate chips (use 8 oz. if you want to cover the entire top instead of drizzling)

No Bake Oreo Bars In Progress


  1. In a food processor, crush the Oreos. Set about 4-6 Oreos aside to use as a topping if you prefer! Depending on how large your food processor is, you might have to do this in steps and place the crumbs into a large bowl. Pulsing the Oreos helps to crush them evenly.
  2. Once the Oreos are crumbs, melt the butter in a large pot and add the marshmallows. Stir until the mixture is smooth and melted.
  3. Quickly pour the melted marshmallows into the Oreo crumbs and stir. This mixture will harden quickly as it cools.
  4. In a pre-greased or parchment-lined square baking pan, press the Oreo mixture down using your hands or a measuring cup. Allow it to set for about 10-15 minutes.
  5. Drizzle with the melted white chocolate and top with the remaining Oreo pieces if you desire!
