Melt butter and marshmallows together in a large pot over medium heat. Stir continuously

When marshmallows are starting to melt, but still lumpy, add the yellow candy melts, reserving just a few to melt and add the eyes on later, and continue to stir until they are all melted together

Add in cereals, and stir until well incorporated, feel free to adjust the amount of cereal as you like to achieve your preferred marshmallow to cereal ratio.

Remove from heat, and being careful not to burn yourself, scoop out some of the mixture and form into a "minion" shape using your hands. It helps to spray hands with non-stick cooking spray first.

Let the minion base set up for 3-5 minutes, then melt the reserved yellow candy wafers in the microwave for about 30-45 seconds in a microwave safe bowl, and use the melted candy wafer like a glue to attach the candy eyes to the bodies of the minions.

Melt the blue candy wafers in a microwave safe bowl by heating for 30 seconds, then stirring, and repeating until melted.

Pour melted blue candy wafers into a plastic bag, cut off one tip, and use it to pipe on the overalls for your minions

Garnish further as desired with candy!
