This Mary Berry cappuccino cake is a light, coffee-scented sponge with a soft, open crumb, sandwiched and covered in a silky, pale-brown buttercream that carries a gentle bitterness from real espresso. The surface is dusted with a fine layer of cocoa powder, exactly as a proper cappuccino would be, giving the finished cake a warm, café-house aroma and a matte, elegant appearance.

What makes this version particularly appealing is how approachable it is. The sponge uses a straightforward all-in-one method, so there is no complicated creaming or folding involved. It works equally well for a weekend bake or a celebration, holding its shape cleanly when sliced and staying tender for several days. From start to finish, it is ready in around 1 hour 15 minutes.

How to Make Mary Berry Cappuccino Cake

Prepare the tins and oven

Heat the oven to 180°C (160°C fan). Grease two 20cm round sandwich tins and line the bases with baking parchment. Using the same tin size for both layers ensures the sponges bake evenly and stack neatly.

Dissolve the espresso

Combine the instant espresso powder with the boiling water in a small bowl and stir until fully dissolved. Leave to cool for at least 5 minutes before adding to the batter. Adding hot liquid to butter can cause the mixture to split, so cooling is important here.

Make the sponge batter

Place the butter, caster sugar, eggs, self-raising flour, baking powder, cooled espresso liquid, and milk into a large bowl. Beat together using an electric hand whisk on medium speed for approximately 2 minutes until the mixture is pale, smooth, and just combined. Take care not to overbeat, as this can tighten the gluten in the flour and produce a dense crumb.

Bake the sponges

Divide the batter equally between the two prepared tins and spread level with a palette knife or the back of a spoon. Bake in the centre of the oven for 22 to 25 minutes, until the sponges are golden brown, have risen, and spring back when lightly pressed in the middle. A skewer inserted into the centre should come out clean.

Cool the sponges

Remove the tins from the oven and leave to cool in the tins for 8 minutes. Then turn the sponges out onto a wire rack, peel off the parchment, and leave to cool completely. Spreading buttercream onto a warm sponge will cause it to melt, so patience here makes a real difference to the finish.

Make the coffee buttercream

Beat the softened butter in a bowl using an electric whisk until pale and creamy, around 2 minutes. Add the sifted icing sugar in two additions, beating between each. Pour in the cooled espresso liquid and beat until the buttercream is smooth and spreadable. Add milk a teaspoon at a time if the buttercream is too stiff to spread.

Assemble the cake

Place one cooled sponge onto a serving plate or board, flat side up. Spread roughly one third of the buttercream evenly over the top using a palette knife. Place the second sponge on top, flat side down, pressing gently so the layers sit flush. Use the remaining buttercream to cover the top and sides of the cake in a smooth, even layer.

Finish and decorate

Hold a fine-mesh sieve above the top of the cake and sift the cocoa powder over the surface in a light, even layer. Arrange a few walnut halves around the top edge if using. The cocoa layer echoes the finish of a proper cappuccino and sets within minutes.

Tips for the Best Mary Berry Cappuccino Cake

01 Why did my cappuccino cake sink in the middle after baking?

A sunken centre usually means the cake was underbaked, or the oven door was opened too early during baking. Always check with a skewer at the minimum baking time, and avoid opening the oven door before 20 minutes have passed.

02 Why does my coffee sponge taste bitter rather than balanced?

This usually means too much espresso powder was used, or the coffee was not fully dissolved before adding it to the batter. Measure carefully and ensure the espresso liquid is completely smooth and lump-free before mixing in.

03 How do I stop the buttercream from becoming too runny?

The most common cause is adding milk too quickly or adding the espresso liquid while it is still warm. Cool the espresso completely and add any extra milk one teaspoon at a time, beating well between each addition until the consistency is right.

04 Why are my sponge layers uneven in height after baking?

This is almost always caused by uneven distribution of batter between the tins. Use kitchen scales to weigh the batter into each tin rather than estimating by eye, and spread the top level before placing in the oven.

05 Why does the cocoa powder on top clump rather than dust evenly?

Cocoa powder absorbs moisture quickly and will clump on contact with buttercream that is too soft or wet on the surface. Chill the assembled and iced cake in the refrigerator for 15 minutes before dusting, and sift from a height of at least 20cm for an even, fine layer.

Serving Suggestions

✦

Serve in thick slices alongside a freshly brewed cup of strong Italian-style coffee to reinforce the cappuccino flavour.

✦

Plate on a white china cake stand and add a light extra dusting of cocoa just before bringing to the table for a clean, café-style presentation.

✦

Pair with a small scoop of vanilla ice cream for a dessert serving, as the cold, plain cream offsets the warm bitterness of the coffee sponge well.

✦

Offer thin slices at room temperature for afternoon tea, where the texture of the buttercream is softer and the coffee flavour more pronounced.

✦

Arrange individual slices in paper cupcake cases for a party buffet or celebration table, making the cake easy to serve without a knife.

◷

Storage

Up to 3 days

Room Temperature

Store the assembled cake in an airtight container at room temperature for up to 3 days, keeping it away from direct sunlight or heat sources.

Up to 5 days

Refrigerator

Place the cake in an airtight container and refrigerate for up to 5 days. Remove from the refrigerator at least 30 minutes before serving, as cold buttercream is firm and the coffee flavour is more muted when chilled.

Up to 3 months

Freezing

Wrap individual sponge layers tightly in cling film, then in foil, and freeze for up to 3 months without the buttercream. Thaw overnight at room temperature, then ice and assemble as normal before serving.

FAQs

01 Can I use filter coffee instead of instant espresso powder in this cake?

Yes, you can use a very strong shot of brewed espresso in place of the dissolved instant powder. Replace the 2 tbsp espresso powder dissolved in 2 tbsp water with 3 tbsp of cooled, strongly brewed espresso. Reduce any additional milk slightly to keep the batter at the right consistency.

02 Can I make the Mary Berry cappuccino cake ahead of time?

The sponge layers can be baked up to 2 days ahead, wrapped tightly, and stored at room temperature. The buttercream can be made the day before and kept covered in the refrigerator. Bring the buttercream to room temperature and beat briefly before assembling, then dust with cocoa just before serving.

03 What size tin works best for this cappuccino cake recipe?

Two 20cm round sandwich tins give the best result for this quantity of batter, producing layers that are deep enough to slice cleanly without crumbling. Using 18cm tins will give deeper, slightly domed layers and may need an extra 3 to 4 minutes in the oven.

04 Can I add walnuts or chocolate chips inside the sponge itself?

Yes. Fold 75g of roughly chopped walnuts or dark chocolate chips into the finished batter before dividing between the tins. Toss them lightly in a teaspoon of flour first so they are less likely to sink during baking.

05 Can I make this cappuccino cake recipe gluten-free?

A direct swap using a good-quality gluten-free self-raising flour blend works reasonably well in this recipe. Add half a teaspoon of xanthan gum if the blend does not already contain it, as this helps the sponge hold together. The texture will be slightly denser than the original but still very pleasant.
