In a large mixing bowl, combine the rolled oats, almond butter, and honey (or maple syrup). Mix until well combined and sticky.
Add the ground ginger, cinnamon, nutmeg, allspice, and salt to the mixture. Stir until the spices are evenly distributed.
Fold in the chopped dates (or raisins), crushed nuts, chia seeds, and cocoa powder (if using) until the mixture is fully combined.
Use your hands to roll the mixture into small balls, about 1 inch in diameter. If the mixture is too sticky, wet your hands slightly to help with rolling.
Place the energy balls on a baking sheet lined with parchment paper and refrigerate for 30 minutes to firm up.
Once chilled, transfer the energy balls to an airtight container for storage. They can be kept in the fridge for up to one week or frozen for longer shelf life.
Notes
Serve in a decorative jar, sprinkled with extra chia seeds or a dust of cinnamon on top.
