Line a 12-cup muffin pan with cupcake liners. Set aside at room temperature. Clear some space in the freezer for this pan—you will need it later.
Melt the chocolate using the double boiler method, or do the following: add chocolate chips and coconut oil to a medium, microwave-safe bowl (large enough to add cereal later). Heat in 20-second increments until softened and melty. Stir in between heating increments, until smooth.
Add cereal to melted chocolate. Using a rubber spatula, stir and fold until well incorporated. Scoop about 2 tablespoons of this mixture into a cupcake liner. Repeat until all liners have been filled. Gently tap the muffin pan to create smooth, even cups.
Freeze for 15-20 minutes. Enjoy! Storing instructions below.
