  • 16 oz mini marshmallows divided use
  • 1 tsp vanilla extract
  • 6 cups Rice Krispies cereal
  • 20 Oreo cookies roughly crushed, divided

Equipment

  • Large Pot
  • 9x9 Baking Pan
  • Large Mixing Bowl
  • Spatula

Method
 

  1. Prepare a 9x9 inch pan by lining with parchment paper and lightly greasing.
  2. Crush 15 Oreos into chunks; break remaining 5 into larger pieces for topping.
  3. Melt butter in a large pot over low heat.
  4. Reserve 2 cups of marshmallows. Add the rest to the butter and melt, stirring constantly.
  5. Remove from heat. Stir in vanilla and salt.
  6. Fold in cereal until coated.

Notes

Use fresh marshmallows for the best texture. Stale ones make hard treats.
