Keto Sponge Cake with Almond and Coconut Flour

This is a basic cake recipe. It’s very simple to prepare and quite cheap. You can find the ingredients in most grocery stores. It is perfect for the keto and  gluten-free diets. The decoration and fillings can be as varied as your imagination allows.

This is a perfect dessert to serve at your next party and no one will know it’s low-carb! The combination of almond flour and coconut flour is a match made in heaven. Using equal parts of each type of flour will make the texture of your baked goods turn out perfect every time.

The problem with traditional cake mixes is that they contain enriched white or wheat flour. These flours are highly inflammatory and contain too many carbohydrates to be consumed on the keto diet.

Almond and coconut flours aren’t just low-carb and gluten-free. They also provide a good source of healthy, anti-inflammatory fats.

This cake recipe is light, airy and delicious. You can use any keto-approved sweetener you have on hand. Examples include stevia, monk fruit and erythritol. You can also use a combination of two sweeteners for a sweeter taste. 

This cake recipe calls for eight eggs and we recommend buying the kind that is organic and pasture-raised. This means that the eggs will contain more healthy fats and other important nutrients. Most pasture-raised brands of eggs do not contain hormones, pesticides or antibiotics either. 

You can change up this recipe by topping it with your favorite low-carb toppings. We suggest using lard, cream cheese and keto sweetener for a perfect final touch. You can also serve it with berries.

It makes a great dessert to serve after dinner with a cup of coffee or you can even enjoy it as a mid-morning snack in between meals. Just be sure to watch your intake of berries if you’re trying to stay in ketosis!
