Measure the honey and peanut butter into a large microwaveable bowl.
Melt the honey and peanut butter together in the microwave for about 30-45 seconds.
Gradually add the oats, a cup at a time, stirring until completely combined.
Stir in any mix-ins!
Roll into balls, then refrigerate for 30 minutes. You can keep them at room temperature, but they're best kept in the fridge, according to my kids. :) Makes 28-32 balls, depending on size.
Notes
OPTION: You can also cut these into bars if you prefer. Press mixture into a 9x13 baking dish, refrigerate for about 30 minutes, then cut into bars.
