Line a baking sheet with parchment paper.
In a mixing bowl, combine rolled oats, cocoa powder, flax seeds, chia seeds, cranberries, coconut, wheat germ, and protein powder (if using).
Add in peanut butter, honey, and vanilla extract.
Stir with a wooden spoon or spatula until the mixture is fully combined.
Fold in mini chocolate chips.
If the mixture is too dry, add more nut butter or honey. If too wet, add a few tablespoons of oats.
Roll the mixture into 1-inch balls using your hands or a cookie scoop.
Place the bites on the prepared baking sheet.
Chill in the fridge for 20–30 minutes until firm.
Store in an airtight container in the refrigerator for up to 1 week.
