I use this vegan fairy cake recipe. It makes about 16.
225g self raising flour
175g caster sugar
2 tsp baking powder
225ml water
6 tbsp oil (coconut, almond, walnut, vegetable, whatever works with your chosen flavours)
1 tsp vanilla essence (or almond, coconut, orange, lemon)
I like it because it doesn’t use any special ingredients, it’s easy to scale up or down and it’s quick and easy- you just chuck everything in one bowl, mix, bake at 180C for 15 minutes.
The great thing about it is you can scale it down to make 2 or 3 different flavours in one go so there is lots of choice eg swap out some flour for cocoa powder (10g cocoa + 90g flour to replace 100g of flour), throw in some vegan chocolate chips; swap the water for cold coffee; swap the water for orange (or other fruit) juice; use different toppings eg lemon drizzle (add lemon zest to the cake mix), raspberry jam and coconut, orange icing on chocolate cake, vegan crumble topping on coffee cake with a drizzle of cinnamon icing, caramelised chopped nuts (add before baking) with cinnamon or rose water drizzle on vanilla, almond or coffee cake, pineapple or orange upside down cake (kirsch soaked cherries with chocolate sponge are fantastic), swirl in jam to make a marble cake, vegan buttercream icing… the combinations are endless.
If you do make different types in one batch, you need to get them in the oven within 15 mins though or you will get big air bubbles in the cake, which look a bit ugly.
