Combine all of the ingredients apart from the maple syrup and nut butter in a food processor and blend until finely chopped.
Add the maple syrup and nut butter and continue to blend until the mixture has started to become smooth but still has some texture. If the mix is too sticky, stir in some ground almonds until it reaches a consistency where you can easily roll it into balls.
With your hands, roll the mixture into bite-sized pieces about the size of ping pong balls, you should get around 15 of them.
If you like, you can roll the energy balls in cacao powder, desiccated coconut, sesame seeds or cinnamon to coat. Store in an airtight container in the fridge for up to 1 week.
