Peanut Butter Slime

  • Add peanut butter to a glass bowl and heat in microwave for 30-60 seconds until melted.
  • In another bowl, mix flour and sugar together.
  • Remove peanut butter from microwave and add flour and sugar combination 1 tablespoon at a time and stir. Gradually add enough flour until peanut butter turns doughy where you can manipulate it.

Chocolate Slime

  • Add chocolate chips to a glass bowl and heat in microwave for 30-60 seconds until melted.
  • Stir in marshmallow fluff and 2 tablespoons of cornstarch. Heat for another 30 seconds if needed.
  • Dust a handful of corn starch on a plate or counter top and knead the chocolate slime a few minutes in the cornstarch. Add more cornstarch if too sticky.
  • This slime is more like putty. If it hardens, you can heat in microwave for another 15-30 seconds.

Reese’s Cups

  • To make play Reese’s cups, line a mini muffin pan with cupcake liners.
  • Add a bottom layer of chocolate slime flatten with a spoon, then add a middle layer of peanut butter slime flatten with a spoon and a top layer of chocolate slime to cupcake liners.
  • Chill in refrigerator for a hour, remove paper liners and play!


Slime and putty should soften after you knead it. If the slime is too hard and crumbly, add it to a bowl with a tablespoon of peanut butter and heat in microwave for 15-30 seconds. Stir and knead. Add cornstarch to prevent stickiness until you achieve desired texture.
Store in the refrigerator in an airtight container. Edible up to 2 days.
