01 - In a large mixing bowl, combine rolled oats, cocoa powder, ground flaxseed or chia seeds if using, and a pinch of salt. Mix thoroughly to distribute all dry ingredients evenly throughout the mixture.
02 - Add the peanut butter, honey or maple syrup, and vanilla extract if using. Stir vigorously until all ingredients are completely combined and a uniform, sticky dough forms.
03 - Gently fold in the mini chocolate chips and chopped nuts if using. Ensure these additions are evenly distributed throughout the mixture for consistent texture in each ball.
04 - Using clean hands or a small cookie scoop, portion the mixture and roll into balls approximately 1 inch in diameter. Apply gentle pressure to ensure the balls hold their shape.
05 - Arrange the energy balls on a parchment-lined tray and refrigerate for at least 30 minutes. This chilling period allows the balls to firm up and hold their shape properly.
06 - Transfer the chilled energy balls to an airtight container. Store in the refrigerator for up to 1 week or freeze for up to 3 months for longer preservation.
