Combine dry ingredients: In a large mixing bowl, combine the rolled oats, chocolate protein powder, cocoa powder, and sea salt. Stir together until the mixture is evenly blended and there are no clumps.

Add wet ingredients: Add the peanut butter, honey (or maple syrup), and vanilla extract to the dry mixture. Using a spatula or your hands, mix thoroughly until all ingredients are fully combined and form a sticky, uniform dough. If the mixture feels too dry, add a little more peanut butter or a teaspoon of water at a time until it holds together well.

Add chocolate chips: If desired, gently fold in the mini chocolate chips for little bursts of chocolate in every bite. Make sure they are evenly distributed throughout the dough.

Shape the balls: Scoop about 1–2 tablespoons of the mixture and roll it between your palms to form a smooth, compact ball. Place each ball on a parchment-lined plate or tray. Continue until all the mixture is used, yielding approximately 12 protein balls.

Chill and set: Place the protein balls in the refrigerator for at least 30 minutes to firm up. This will make them easier to handle and give them a perfect bite-sized texture.

Serve and store: Once chilled, transfer the protein balls to a serving plate or store them in an airtight container in the refrigerator for up to a week. These make a perfect quick snack, pre-workout boost, or on-the-go treat.
