Preheat the oven to 180 °C (top/bottom heat). Grease an Easter lamb baking tin with 1 tbsp margarine, pour in the semolina and toss until the entire surface is covered with semolina.
Tap off any excess semolina.
In a bowl, beat the soft margarine, vanilla sugar, grated lemon zest and sugar with a hand mixer until frothy.
Gradually stir in the plant milk. Combine the flour, almonds and baking powder, pass through a fine sieve and fold into the mixture.
Pour the batter into the prepared tin and bake in the oven for approx. 40 mins.
Then leave the tin to cool slightly, remove the cake from the tin and leave to cool completely on a wire rack.
Dust the cooled lamb with powdered sugar and serve.
