In a large mixing bowl, combine the rolled oats, instant espresso powder, cocoa powder, and sea salt. Mix well to ensure the espresso is evenly distributed.
Add the almond butter, honey (or maple syrup), and vanilla extract to the dry ingredients. Stir until a thick, sticky dough forms.
Fold in the dark chocolate chips and shredded coconut, if using, until evenly incorporated.
Using your hands, scoop out tablespoon-sized portions of the mixture and roll them into balls. Place the balls on a parchment-lined baking sheet.
Once all the mixture is rolled into balls, refrigerate for at least 30 minutes to firm up and allow the flavors to meld.
Store the energy balls in an airtight container in the fridge for up to a week, or freeze for longer storage.
Notes
Arrange the energy balls on a rustic wooden board, dust with cocoa powder, and serve with almond butter for dipping.
