01 - Toast the pecans in a dry skillet over medium heat for 3–4 minutes, stirring frequently, until fragrant. Allow to cool completely.
02 - In a food processor, pulse the cooled pecans until finely chopped. Avoid over-processing to prevent a paste-like consistency.
03 - Add the rolled oats, chia seeds, and salt to the food processor with the chopped pecans. Pulse briefly to combine.
04 - Add the maple syrup and vanilla extract to the mixture. Pulse until the ingredients begin to clump together, forming a cohesive mass that holds its shape when squeezed.
05 - Transfer the mixture to a mixing bowl and gently stir in the dark chocolate chips or chopped dark chocolate.
06 - Using your hands, portion approximately 1 heaping tablespoon of the mixture and roll it into uniform 1-inch diameter balls.
07 - Arrange the formed balls on a parchment paper-lined baking sheet. Refrigerate for a minimum of 20 minutes to allow them to firm up.
08 - Store the energy balls in an airtight container in the refrigerator for up to 1 week, or freeze for up to 1 month.
