Total Time 20 minutes mins
Mixing bowl
Measuring cups
Rubber spatula
Baking sheet optional
Parchment paper optional
Scooper optional
- 3 cups quick oats
- 2 cups peanut butter
- 1/2 cup honey
- 1/2 cup ground flaxseed
- 1/2 cup mini m & m candies
Add all ingredients to a bowl and stir to combine. The mixture will be sticky and a bit hard to mix at first—use clean hands if a spoon isn’t working.
Roll or scoop 1–2 tablespoons of the monster cookie protein ball mixture into balls and place on a parchment-lined sheet pan. If the mixture isn’t sticking, add a little more peanut butter. If it’s too sticky, mix in more oats.
Freeze overnight (or until firm), then transfer to an airtight container or freezer bag. Freezing helps them last longer, but it’s optional—if not frozen, store in the fridge for up to one week.
