Place walnuts and dates in the food processor and pulse until they combine together.
Then add the carob and ramon nut powder and pulse until the mixture forms into a dough. Be careful not to grind too finely. You should still be able to see small chunks of walnuts.
Add the optional coconut oil if you prefer or if the mixture is too dry and pulse once again.
Press the mixture evenly into an 8 by 8 inch baking tray and place into the fridge to set for at least one or two hours.
Cut evenly into 16 squares. You might need to wait a little while for it to soften to cut easily.
Notes
These will keep in the fridge for at least a week but you can store them in the freezer for a month.
