Unfortunately, since these are no-bake, wheat flour doesn't work as a 1:1 substitute here. I tried it and it led to super-dense truffles that I personally did not like. I haven't tried it with almond or coconut flour but it may work. Since it's no-bake you can keep adding flour until it is the right consistenc. However, I really did intend for this recipe to be made with cassava flour for the best results.
