For the filling

  • 100g icing sugar, sifted, plus a little extra for dusting
  • 150ml double cream
  • 100g mascarpone, at room temperature


  1. Heat oven to 180C/160C fan/gas 4. Butter 2 x 20cm round cake tins and line with baking parchment. Set aside 1 tbsp of the coffee for the filling.

  2. Beat the butter, flour, sugar, baking powder, eggs, vanilla and half the remaining coffee in a large bowl with an electric whisk until lump-free. Fold in the finely chopped walnuts, then divide between the tins and roughly spread. Scatter the roughly chopped walnuts over one of the cakes. Bake the cakes for 25-30 mins until golden and risen, and a skewer poked in comes out clean. Drizzle the plain cake with the remaining coffee. Cool the cakes in the tins.

  3. Meanwhile, make the filling: beat together the icing sugar, cream and mascarpone, then fold in the reserved 2 tbsp coffee. Spread over the plain cake, then cover with the walnut-topped cake and dust with a little icing sugar.

Its a doddle, or were you bad at maths?

Lovely cake, the sponge went a bit soggy but i think that was my oven rather than a fault with the recipe. The filling IS TO DIE FOR!!! :)

Second time I have made this - first time was in a 23" tin, I put the filling on top - and the left over mixture I baked in muffin tins. I made real lavaza crema gusto coffee - as I don't like instant - personally I think it adds a better flavour. I also double the amount of vanilla essence. This time I have two 20" tins and a fan assisted oven so fingers crossed!!!

made the cake very good, but we live in the Canary Islands and I had to put it in the fridge as I was worried about the filling, in the heat which we have here which I think and made the cake go a bit hard as any one got any suggestions on how to keep the cake in heat.

Fantastic cake, just put all ingredients straight into processor and mix altogether. My family love it.

It all worked very well for me and is quite subtle. All I would say is make sure you spread out the cake mixture evenly in the tin as it is quite solid before cooking. My cake ended a little uneven so I had to slice some off in the middle to keep it even.

The cake is excellent but the filling didn't work, I think the measurements are wrong too sloppy.

I make coffee and walnut cake very often and i like to change recipe. This is a fab cake i didnt use plain cake just put coffee in, i also drizzled coffee icing over and then sprinkeld on the walnuts.

This cake was delicious, especially the coffee cream! Usually I find coffee and walnut cake is too overpowered by strong coffee and not enough walnuts, but this was just right. The only thing I'd change next time is drizzling the coffee over one layer of the cake. To me it spoiled that layer, although others who tasted it said they liked it.
