**Mix Dry Ingredients:** In a large bowl, combine the rolled oats, shredded coconut, ground flaxseed, chia seeds, matcha powder, and a pinch of sea salt. Mix well.
2. **Add Wet Ingredients:** Add the almond butter, honey or maple syrup, and vanilla extract to the dry ingredients. Mix until everything is well combined.
3. **Stir in Extras:** Fold in the dark chocolate chips if using.
4. **Form Balls:** Using your hands, form the mixture into small balls, about 1 inch in diameter. If the mixture is too sticky, refrigerate it for 10-15 minutes to make it easier to handle.
5. **Chill:** Place the energy balls on a baking sheet lined with parchment paper and refrigerate for at least 30 minutes to firm up.
6. **Store:** Transfer the chilled energy balls to an airtight container. Store in the refrigerator for up to two weeks
