Simple LimeOat Cake
Moist vegan lime cake with oats and a brown-sugar lime topping

This recipe is deliberately straightforward to handle. Lime juice brings freshness to both cake and topping without requiring any zest. Finely ground oats give the cake substance, while apple purée keeps the crumb moist.
Ingredients
For the cake
- 180 g German Type 630 spelt flour or plain wheat flour
- 70 g rolled oats
- 130 g sugar
- 120 g apple purée
- 70 g neutral vegetable oil, such as rapeseed oil
- 80 ml soya or oat milk
- 60 ml lime juice
- 2 tsp baking powder
- 1/2 tsp bicarbonate of soda
- 1/2 tsp salt
For the brown-sugar lime topping
- 50 g brown sugar
- 20 g vegan margarine
- 15–20 ml lime juice
- 1 pinch of salt

You will also need
- about 3 limes in total
Method
Prepare

Heat the oven to 175 °C conventional. Grease an approximately 25 cm loaf tin or line it with baking paper. Grind the rolled oats finely.
Combine the dry ingredients

Mix the spelt or wheat flour, ground oats, sugar, baking powder, bicarbonate of soda and salt evenly in a bowl.
Make the batter

Add the apple purée, oil, plant milk and 60 ml lime juice. Mix only until an even batter forms. It should be thick yet fall slowly from a spoon. If it seems distinctly too firm, add a small splash of plant milk.
Bake

Spoon the batter into the prepared loaf tin and smooth the surface. Bake at 175 °C in a conventional oven for about 45–55 minutes. Start testing with a wooden skewer after roughly 45 minutes. A few moist crumbs are good; no liquid batter should remain.
Make the topping

Put the brown sugar, margarine and initially 15 ml lime juice in a small saucepan. Heat while stirring until the margarine and sugar have melted. Simmer briefly and stir in a pinch of salt. If the mixture becomes too thick, add a little more lime juice.
Glaze the cake

Pierce the still-warm cake several times with a wooden skewer and spread the warm topping over it. Some may soak into the cake while a thin caramel-like layer remains on top.
Leave to cool

Leave the glazed cake to cool in the tin for about 15–20 minutes. Carefully lift it out, then leave it to cool completely until the topping has set.
