Mary Berry Chocolate Courgette Cake is a moist chocolate sponge made with cocoa powder, grated courgette, flour, eggs, butter, and sugar. The courgette adds moisture and softness without affecting the flavour, resulting in a rich, tender cake that holds its shape beautifully and tastes even better the next day.
250g courgettes, grated
175g caster sugar
125g unsalted butter, softened
2 large eggs
200g self-raising flour
50g cocoa powder
1 teaspoon vanilla extract
½ teaspoon baking powder
A pinch of salt
Optional: chocolate chips for extra richness
Grate the courgettes finely and squeeze lightly to remove excess moisture, but avoid pressing them completely dry.
Beat softened butter and caster sugar until pale and fluffy, creating a light base for the cake.
Beat the eggs in one at a time, then stir in vanilla extract to enhance the flavour.
Fold in self-raising flour, cocoa powder, baking powder, and salt gently to avoid overworking the batter.
Stir in the grated courgette and chocolate chips if using. The batter will look thick but will loosen as the courgette releases moisture.
Pour the batter into a greased 20cm tin and bake at 180°C (160°C fan) for 40–45 minutes, or until the cake is risen and a skewer comes out clean.
Allow the cake to cool in the tin for 10 minutes, then transfer to a wire rack. Dust with icing sugar or spread with chocolate icing if desired.
