Do you have other recipes where you use zucchini flour?

Not yet! This is new to me too! I love the flavor and the texture so I definitely plan on making more recipes.

Is zucchini flour a one to one ratio replacement for other keto flours?

Yes, it is a one to one ratio replacement if you are using coconut flour. I have found that both zucchini flour and coconut flour do require a bit of liquid to flour ratio so that your recipe does not come out dry or dense.

It is not a one to one ratio for almond flour though. Almond flour does not hold the liquids like the zucchini does. You would only need to use 1/3 the amount of zucchini flour to almond flour.

Why we love this keto bread recipe and you will too!

It tastes fantastic!
It has a wonderful texture!
It’s not heavy like other keto bread recipes that use almond flour.

Once you realize how wonderful this flour is, you will want to always have some in your pantry! I can’t wait until they start producing this in mass amounts and selling it at our local grocery stores! I’d buy it!
