Line a cupcake pan with cupcake liners. Set aside.
In a large microwave-safe mixing bowl, melt butter and marshmallows. Do it in 20 seconds intervals, mixing between each until marshmallows and butter are melted. Generally it takes about 80-90 seconds.
Add the honey and peanut butter. Whisk until all combined.
Add the Cheerios and the Golden Grahams.
Mix until all the cereal is coated in the marshmallow mixture.
Using a large cookie scoop (approximately 2 tablespoons) form the balls.
Place them in the cupcake liners.
Then put the cupcake pan in the refrigerator for about 30 minutes or longer to allow time to set. Or let it sit on the counter for about an hour to set.
