Coffee and Walnut Cake with Cream Cheese

A British Teatime Favourite, with a Tangy Twist

Coffee and walnut cake is one of those bakes that quietly holds its ground on any tea table. It is not flashy, it does not demand a blowtorch or a sugar thermometer, and it never seems to go out of fashion. The classic version is sandwiched with coffee buttercream, which is lovely but can tip into cloying territory by the second slice. Swapping that for a cream cheese frosting changes everything. You still get the deep, roasted hit of espresso, but the tang of the cheese cuts through the richness and keeps you coming back for more.

The sponge itself is where the real work happens. Get that tender, walnut-flecked crumb right and the filling barely has to try. Here is how to do it properly, with the sort of detail that makes the difference between a good cake and one that vanishes before the kettle has boiled twice.

What You Will Need

This makes two 20cm round sponges, enough for a generous eight to ten slices. Use tins with loose bases and line the bottoms with greaseproof paper.

• For the sponge: 225g unsalted butter, softened; 225g light soft brown sugar; 4 large eggs, at room temperature; 225g self-raising flour; 1 tsp baking powder; 100g walnuts, finely chopped; 2 tbsp strong espresso, cooled; 1 tsp vanilla extract; a good pinch of fine salt; 1–2 tbsp milk if needed.
• For the frosting: 200g full-fat cream cheese, straight from the fridge; 100g unsalted butter, softened; 250g icing sugar, sifted; 1–2 tbsp cooled espresso; ½ tsp vanilla extract; a pinch of salt.
• To finish: 40g walnut halves, lightly toasted, plus a dusting of cocoa or a few coffee beans if you like.

Two notes on ingredients. First, use full-fat cream cheese in a block, not the spreadable sort in a tub — the latter is wetter and will give you a slack, runny frosting. Second, light soft brown sugar gives a faint caramel note that flatters the walnuts, but caster sugar works perfectly well if that is what is in the cupboard.

Baking the Walnut Sponges

Heat the oven to 180°C (160°C fan, gas mark 4) and line your tins. Toast the walnuts for the sponge briefly in a dry pan, then cool and chop them finely — not to dust, but small enough that they distribute evenly rather than tearing holes in the crumb.

Cream the butter and sugar for a full four to five minutes until noticeably pale and fluffy. This is not a step to rush; the air you beat in now is what lifts the cake later. Add the eggs one at a time, beating well after each and adding a spoonful of the weighed flour if the mixture looks like it might curdle.

Fold in the remaining flour, the baking powder and the salt with a large metal spoon, then stir through the chopped walnuts, espresso and vanilla. The batter should drop from the spoon with a reluctant wobble. If it is stiff, loosen it with a tablespoon of milk.

Divide between the tins, level the tops and bake for 22–25 minutes, until a skewer comes out clean and the sponges spring back when pressed lightly in the centre. Leave them in the tins for ten minutes, then turn out onto a wire rack and cool completely. Warm sponge plus cream cheese frosting equals sliding layers, so patience here is non-negotiable.

Making the Cream Cheese Frosting

Beat the softened butter with the icing sugar, espresso, vanilla and salt until smooth and pale. It will look thick at this stage — that is fine. Now add the cold cream cheese and beat only until it is just combined, perhaps twenty to thirty seconds. Overworking is what turns a firm frosting into a puddle, because the more you beat cream cheese, the more it loosens.

Taste and adjust. You want the coffee to be assertive enough to stand up to the walnut, so add another teaspoon of espresso if it tastes shy. If the frosting feels soft, chill it for twenty minutes before using.

Assembling and Finishing

Set one sponge on your plate or stand, flat side up. Pile on roughly a third of the frosting and spread it to the edges with a palette knife, working with a light hand so you do not drag crumbs through it. Sit the second sponge on top, press down gently, then cover the top with the remaining frosting, swirling it with the back of a spoon or a small offset spatula.

Arrange the toasted walnut halves around the edge or in a loose pile in the centre. A light dusting of cocoa powder over the top looks smart, though do it just before serving — it will absorb moisture and darken if left for hours. For a cleaner slice, chill the assembled cake for thirty minutes before cutting, and use a knife dipped in hot water and wiped dry between cuts.

Storage and a Few Practical Notes

Because of the cream cheese, this cake belongs in the fridge. Keep it covered and it will be at its best for three days; bring slices out twenty minutes before eating, as the sponge firms up when cold and the flavours open out at room temperature. It also freezes well un-iced — wrap the cooled sponges tightly and freeze for up to two months, then defrost overnight before filling.

• If your sponges domed in the oven, trim them flat with a serrated knife before stacking.
• Walnuts go stale quickly; buy them fresh and sniff before using. A musty smell means they are past it.
• For a stronger coffee hit, brush the cooled sponges with a little extra espresso syrup before filling.

Serve it with a pot of strong Assam or, if you are feeling indulgent, a small glass of something sweet and fortified. Either way, it is the sort of cake that makes an ordinary afternoon feel properly looked after.
