This moist keto lemon blueberry cake is a slice of Spring! The sharp lemon flavour is balanced by the sweetness of the blueberries. Baked with coconut flour it's a great low carb and gluten free cake.
This cake is great by itself with no frosting but feel free to slather it with a cream cheese frosting. It's baked in a single cake tin but double up the mixture to make a sandwich cake.
How to make a keto lemon blueberry cake
As with many of my coconut flour cake recipes, I separate the eggs to whisk up the egg whites. Coconut flour can be dense at times and I've found that folding in firm egg whites helps give a light sponge. Since we are baking without gluten we need every help we can to get a lift in our cakes!
Can I replace the coconut flour with almond?
Almond flour can be used in place of coconut flour if you prefer to bake with it. The volume should be changed to 1 ½ cups almond flour and I would reduce the eggs to 4. Almond flour requires less liquid than coconut flour.
I would still separate the eggs to keep this lemon blueberry cake light and moist.

Can I make muffins with this recipe?

Nice idea! Yes you could but I'd reduce the baking time by about 5-8 minutes.
