To the food processor, add the walnuts, almond flour, coconut flour, and sea salt. Blend until a semi-fine meal is achieved. Add dates back in (in bite-sized pieces) as well as the vanilla extract. Pulse until a loose dough forms. Be careful not to over-blend. You're looking for a pliable dough, not a purée.
*Can sub 1/2 tsp vanilla powder or paste per 2 tsp vanilla extract.
