Add the chocolate chips and creamy peanut butter to a bowl, then microwave in 30 second increments (stirring between each increment) until the chocolate has melted and is completely smooth.

Add in the rice cereal and mix everything together to combine.

Scoop the mixture into the muffin liners then transfer to the freezer for about an hour, or until solid. Remove the cups from the freezer and either enjoy right away or store in the fridge for later!
