These are a favorite holiday treat, traditionally known as Buckeyes (named after the Ohio state tree nut). This version is adapted to be high protein for a fun mid-day snack.
Add peanut butter, honey, vanilla, salt, and protein powder in a bowl and mix until combined. Scoop into 1-2 tbsp size balls and roll in hands until smooth. Chill in fridge until they firm up a bit (at least 30 min). Melt chocolate with coconut oil in microwave. Dip peanut butter balls 3/4 of the way in the chocolate, making them look like buckeyes.
