Place the flax seeds in a food processor. Grind the flax seeds until they start to break up. (They do not have to be fully ground into powder.)
Add the oats, coconut, nut butter, vanilla, cinnamon, salt, nutmeg, and maple syrup. Turn the processor on high and mix until the ingredients form a thick consistent crumble.
Add in the raisins and chocolate chips. Mix these ingredients in by hand.
Use a 1 ½ tablespoon cookie scoop to portion out even balls of dough. Roll the dough into tight balls.
Place the energy balls into an airtight container and keep refrigerated until ready to serve.
