  • ¼ cup unsalted butter
  • 1 10 oz bag mini marshmallows about 5 cups
  • ½ cup peanut butter
  • 6 cups Rice Krispie cereal*
  • 8 oz chocolate chips about 1 ⅓ cups
  • 2 teaspoons vegetable oil


  • Lightly grease a 9x13 inch pan with butter or non-stick cooking spray. 
  • In a large saucepan melt the butter, mini marshmallows and peanut butter together over low heat while stirring gently.  
  • Once melted, remove from the heat and stir in the Rice Krispies.
  • Press the mixture into the pan (lightly spray your hands with non-stick cooking spray to avoid the mixture sticking to your hands).
  • Add the chocolate chips (or chopped chocolate) to a medium-sized heatproof bowl. Microwave for 45-second intervals on medium power (not high or standard), stirring in between each burst.
  • Once almost melted, stir until smooth and stir in the vegetable oil.
  • Pour the chocolate over the top of the bars and let harden at room temperature (about 2 hours).
  • Cut into squares and store in an airtight container at room temperature.


For softer, gooier bars - only use 5 ½ cups Rice Krispies. 
Store in an airtight container at room temperature for up to 3 days.
