Line a baking sheet with parchment paper and set aside.
Combine dates and cashews or pecans and chia seeds in a food processor. Pulse until mixture is finely chopped. Add remaining ingredients, then process until mixture starts to come together in a large ball.
Roll tablespoon-sized portions of the mixture into balls, roll in coconut, roll in oats and place them on prepared baking sheet.
Chill 30-60 minutes until set. Store leftovers in an airtight container at room temperature or in the fridge/freezer.
