Ingredients for healthy lemon cake:
- Almond flour
- Tapioca flour
- Coconut flour
- Coconut oil

Why do you use 3 different kinds of flour?
They all serve a purpose for the texture! The gluten in a traditional cake gives it structure and when you remove it you need a combination of flours to create a similar texture. One of the flours alone, like almond flour, doesn't have the same structure so a combination is necessary.
How do you make a gluten free cake moist?
They key to a moist gluten free lemon cake is the balance between wet and dry ingredients. If you don't have enough wet ingredients the cake can be dry. Be sure to measure everything correctly so the ratios are exact.
