Preheat oven to 350. Grease 8 x 8 baking dish with coconut oil or leaf lard.
Add tigernut flour, salt and baking soda into Cuisinart (food processor) and pulse until combined
Add chocolate chunks and pulse until combined. You want the chocolate to be in tiny pieces
Add whole pitted dates and pulse until combined. Again, pulse until the dates are in tiny pieces
Add eggs and pulse until combined
Add coconut oil or leaf lard, date syrup and stevia. Pulse until smooth. This will be a thick batter
Add batter to greased baking dish. Smooth it with your spatula or a damp hand
Bake 22-24 minutes
Cool on baking rack and try not to eat until cool.
I prefer using coconut oil but if that taste is too strong, try leaf lard. It is a clean tasting fat that won't bring any additional taste into the brownie.
