Step-by-Step Guide to Making Mary Berry Plum Cake

• 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.

What I Got Wrong (And How I Fixed It)

• The cake was too wet — using fewer plums or patting them dry solved the issue.
• The plums sank — lightly coating the tops with flour kept them from sinking deeply.
• The sponge tasted dense — creaming the butter longer improved the texture.
• The top browned too quickly — covering loosely with foil halfway worked perfectly.

FAQs

Why did my plum cake turn out too wet in the centre?

A plum cake becomes wet when the fruit releases too much moisture during baking. Patting the plums dry, using fewer overly juicy plums, or baking the cake for an extra 5–10 minutes helps achieve a firm, fully set centre.

How do I stop the plums from sinking to the bottom of the cake?

Plums sink when the batter is too loose or the fruit is too heavy. Placing the plums cut-side up and dusting them lightly with flour before arranging them on top helps them stay near the surface.

Why is my plum cake dense instead of light and fluffy?

A dense cake usually means the butter and sugar weren’t creamed enough or the batter was overmixed after adding flour. Creaming thoroughly and folding gently helps keep the crumb soft and airy.

How do I know when my plum cake is fully baked?

The cake is ready when a skewer inserted into the sponge—not the plums—comes out clean. If the top browns too quickly before the centre sets, covering the cake loosely with foil ensures even baking.
