Line a cupcake pan with cupcake liners. Set aside.
In a large microwave-safe mixing bowl, melt the butter and marshmallows at 20 second intervals in the microwave. Mix in between each interval. It takes about 90 seconds to melt.
Add the honey and peanut butter to the mixing bowl. Whisk until ingredients are combined.
Add the Cheerios and Golden Grahams. Mix until all coated.
Using a large cookie scoop, or approximately 2 tablespoons, form balls by rolling them in your hands and placing them in the prepared cupcake pan.
Place in the fridge for 45 minutes or longer to allow them to set.
