1. In a bowl put the sugar, oil, lemon zest and vanilla essence, and mix.
2. Add the plant-based milk and flour, and mix again.
3. Add the strawberries (reserve some for garnish) and mix again until everything is completely integrated.
4. Transfer the mixture to a greased baking pan, add more strawberries on top for garnish (optional) and bake for 1 hour over low heat.
5. Remove and prick the cake with a fork: if it comes out dry, it's ready (otherwise, bake for a few more minutes).
