In a large mixing bowl, combine the creamy peanut butter and honey. Stir until the mixture is smooth and well-blended.
Add the old-fashioned oats, vanilla protein powder, and fine sea salt to the peanut butter mixture. Stir well until fully incorporated.
Gently fold in the mini M&Ms and mini chocolate chips until evenly distributed.
Roll small amounts of the mixture into balls about 1 inch in diameter and place them on a baking sheet lined with parchment paper.
Chill the baking sheet in the refrigerator for at least 30 minutes to firm up the energy balls.
