Mary Berry Plum Cake is a tender sponge cake topped—or layered—with fresh plums that bake into the batter, releasing their juices and giving the cake a fruity, jam-like finish. It’s a classic British-style bake that highlights seasonal fruit while keeping the preparation simple and quick.
175g soft butter
175g caster sugar
3 large eggs
175g self-raising flour
1 tsp baking powder
½ tsp ground cinnamon (optional)
1 tsp vanilla extract
5–6 ripe plums (halved and stoned)
1–2 tbsp demerara sugar (for sprinkling)
Prepare the tin: Line an 8-inch round cake tin with baking parchment.
Cream butter and sugar: Beat until pale and fluffy for maximum lift.
Add eggs one at a time: Mix well after each addition to prevent curdling.
Fold in dry ingredients: Add flour, baking powder, and cinnamon gently.
Add vanilla: Stir lightly to enhance the flavour.
Spread batter in tin: Smooth the top with a spatula.
Arrange the plums: Place plum halves cut-side up across the surface.
Sprinkle demerara sugar: Adds sweetness and a slight crunch.
Bake the cake: Bake at 180°C (350°F) for 45–50 minutes until golden.
Check doneness: A skewer should come out clean from the cake portion.
Cool properly: Allow the cake to cool in the tin before slicing.
