Place the dates, almonds, oats, flaxseed and chia seeds in a food processor and blend until everything is very finely chopped. This will probably take a couple of minutes.
Next, add the peanut butter, vanilla extract, maple syrup and chocolate chips and blend again until everything is well combined. You don't want the chocolate chips to get too finely chopped up so don't blend the mixture for too long.
Tip the mixture into a bowl and use your hands to roll it into small balls. If you find that the mixture is difficult to stick together then stir in a drop of water, a little at a time, until it clumps together easily.
If you like you can roll the energy bites in cacao powder then place them in an airtight container in the fridge where they will keep for at least a week.
