Although we’re not vegan and love gluten, we do have friends that are allergic to gluten that we would love to feed with our cakes.

Substitutes when baking with gluten-free flour

Gluten are proteins found in grains, including wheat, rye, spelt, and barley. It helps foods maintain their shape, acting as a glue that holds food together. Food that are high in gluten are bread, pasta, cereals, beer and yes mostly all the cakes and pastries you’ll find here. Most people can tolerate gluten, but some people with certain health conditions are facing problems when eating gluten. Most common symptoms are bloating, headaches, constipations, skin rashes and even depression. Luckily there is a few substitutes for gluten and if you use the right combinations and proportions delicious cakes can be made.

When baking gluten-free cakes there’s substitute flours like oat flour, coconut flour, buckwheat flour and almond flour. In this recipe we use almond flour because it adds moisture and when paired with oat flour it can make the cake more dense. We use chia seeds as a substitute for the gluten. It helps to bind the ingredients together.

More secret ingredients…

What makes this the best gluten-free vegan cake you ever baked? It has the perfect texture, right amount of moist and has an interesting tang flavor. It’s the vegan buttermilk that adds a little bit of fat. Instead of using yoghurt or sour cream we add lemon juice to almond milk which makes a vegan buttermilk. The buttermilk combined with baking soda creates air bubbles which can give gluten free baking goods a fluffy and light texture.

Finishing with a beautiful glaze made of soaked cashewnuts, coconut cream, lemon juice and syrup and topped with fresh berries. Don’t forget to soak the cashewnuts in water 2 hours before you start making the cake!

Creamy dreamy cashewnut frosting

This cake isn’t covered in your average sweet topping. Instead of using heavy cream cheese, we use coconut cream and soaked cashewnuts. Cashewnuts are loaded with manganese, phosphorus, copper, vitamin K and magnesium. The frosting is naturally sweetenend with maple syrup and vanilla extract, or any natural syrup you prefer. The result is a creamy, rich, thick perfectly naturally sweetened frosting.
