Strawberry jam and coconut sponge cake just like the old-school dessert!
Preheat your oven to 180°C/350°F (or 160°C/325°F if you're using a fan or convection oven). Line an 8x10" tray with baking paper.
Mix the soy milk with the apple cider vinegar and set aside for 5 minutes. This will act as your vegan buttermilk.
In a large bowl, mix together the flour, baking soda and caster sugar.
Add the buttermilk to the bowl along with the oil and vanilla extract. Mix well until you have a smooth cake batter.
Transfer the cake batter into your lined tin and spread it out evenly. Bake for 22-25 minutes, or until a toothpick through the centre comes out clean.
Let the cake cool in the tin for around 20 minutes, then flip it out onto a wire rack. Peel off the baking paper and leave the cake to cool completely.
Once the cake is cool, spread over the strawberry jam then sprinkle over the desiccated coconut. Cut into 12 square slices and enjoy!
