I've been using a lot of coconut flour lately and I love it. So delicious and versatile, and replaces a ton of white flour in my diet. Actually adds back in a lot of the recipes that I don't make anymore for wanting to avoid white flour.
The first thing to know about coconut flour is that it will never produce a product quite like a wheat flour baked good or gravy. If you want foods that pretend to be white flour foods, it's not really gonna happen. I don't think there is such a thing as an equal replacement for the divine foods of the gods that white flour creates.
That said, a coconut flour recipe is good shit in its own right. The important thing to me is that the coco flour foods are delicious and satisfying to me, whether they taste like wheat flour foods or not, and so far, coconut flour has exceeded my expectations.
The second thing to know is that coconut flour is way more absorbent so you only need anywhere from 1/4 to 1/2 of the amount of wheat flour in a recipe.
My favorite coconut flour things so far are microwave mug cake and sausage gravy. Fantastic! I've made a wonderful banana bread and lemon cake as well.
Again, there is nothing on this earth like sausage gravy made with white flour, but the coconut flour gravy is so tasty. Very good replacement. I also use vegetable/tofu sausage (it was tough to find one I liked, Morning Star), so I am very pleasantly surprised at what is, I admit, rather an abomination of traditional sausage gravy.
I make it the same way as white flour gravy just with less coco flour - cook the sausage and crumble it, add butter or oil if needed for vegetarian sausage, fry up the coco flour until browned (not too brown... coco flour burns at a lower temp than white flour, apparently, and might turn a little bitter), add milk, and simmer stir to the thickness you like.
The chocolate mug cake is super easy. I spray a bowl (mugs overflow in the microwave) with baking spray, add all ingredients and stir until smooth, and then nuke for two minutes. Done. I have the recipe memorized already.
2 tbsp coconut flour
1 tbsp cocoa powder
1/8 tsp baking soda
1/8 tsp baking powder
dash of salt
2 tbsp of sugar or other sweetener of your choice
1 egg (vegetarians can use aquafaba, but I tried that and was not as pleased with the texture or the taste. good thing I'm not a vegetarian)
1/3 c milk
You can add vegetable or coconut oil if you want a richer, moister cake, but I usually top it with ice cream, so I don't really need the extra moisture or richness.
I've also made this mug cake with lemon or vanilla instead of cocoa. The vanilla was kind of meh, but the lemon was awesome.
My next coco flour experiment will be sponge cake.
