Ingredients
- 250g plain flour (all-purpose flour)
- 200g caster sugar
- 30g cocoa powder (unsweetened, for chocolate version)
- 1 tsp baking powder
- 1 tsp bicarbonate of soda
- ½ tsp salt
- 1 tbsp ground flaxseed + 3 tbsp warm water (flax egg)
- 240ml unsweetened oat milk or any plant-based milk
- 80ml vegetable oil (sunflower or light olive oil)
- 1 tsp vanilla extract
- 120g dairy-free yogurt (soya or coconut works well)
- For the frosting:
- 150g dairy-free margarine (softened)
- 300g icing sugar (powdered sugar)
- 2 tbsp plant-based milk (for consistency)
- 1 tsp vanilla extract
- Optional: food colouring or natural beetroot powder for colour
Equipment
- Two 8-inch (20cm) round cake tins
- Mixing bowls (medium and large)
- Electric hand mixer or stand mixer
- Measuring cups and spoons
- Spatula and whisk
- Cooling rack
- Sieve (for flour and cocoa powder)
- Parchment paper
- Cake stand or plate for serving
Instructions
- Prepare the flax egg: In a small bowl, combine the ground flaxseed with warm water. Stir and let it sit for 5-10 minutes until it becomes gel-like.
- Preheat your oven: Set to 180°C (fan) / 200°C (conventional) / 350°F. Grease and line two 8-inch cake tins with parchment paper.
- Sift dry ingredients: In a large bowl, sift together the flour, caster sugar, cocoa powder (if using), baking powder, bicarbonate of soda, and salt. Mix well to combine.
- Mix wet ingredients: In another bowl, whisk the flax egg, oat milk, oil, vanilla extract, and dairy-free yogurt until smooth.
- Combine wet and dry: Gradually pour the wet ingredients into the dry ingredients. Use a spatula or mixer to blend until the batter is smooth and lump-free.
- Divide the batter: Evenly split the batter between your prepared cake tins. Smooth the tops with a spatula.
- Bake: Place the tins in the oven and bake for 25-30 minutes. Check doneness by inserting a skewer — it should come out clean.
- Cool: Remove cakes from the oven and let them cool in the tins for 10 minutes. Then transfer to a wire rack to cool completely before frosting.
- Make the frosting: Beat the vegan margarine in a bowl until creamy. Gradually add icing sugar, beating continuously. Add vanilla and a splash of plant milk to reach a spreadable consistency. If desired, add food colouring.
- Assemble the cake: Place one cake layer on your serving plate. Spread a generous amount of frosting on top. Place the second layer on top and cover the entire cake with the remaining frosting. Decorate as you like.
- Chill and serve: For best results, chill the cake for at least 30 minutes before slicing. Enjoy your vegan birthday cake!
Tips & Variations
Tip: For an even moister cake, add 1 tablespoon of apple cider vinegar to the wet ingredients — it reacts with the baking soda to give a lovely rise and tender crumb.
You can easily swap the cocoa powder for an equal amount of plain flour if you prefer a vanilla or fruit-flavoured cake. Add lemon zest or mixed berries to the batter for a fresh twist.
For a festive look, try piping the frosting using a star nozzle or layering with vegan jam or fruit curd. To make the cake gluten-free, substitute the plain flour with a 1-to-1 gluten-free baking mix.
