5. Add the flour, baking powder and walnuts and stir well to completely combine.
6. Spoon the cake mixture into two lined and greased 20cm/8in cake tins.
7. Transfer to the oven to bake 25-30 minutes, or until a skewer inserted into the centre of the cake comes out clean and the cake is golden-brown.
8. Remove the cakes from the oven and leave to cool on a wire rack.
9. For the butter cream topping, beat the margarine and icing sugar together in a small bowl until pale and light.
10. Add the espresso and mix well.
11. Spread the butter cream over the top of each cake, then place one cake on top of the other.
12. Decorate the top of the cake with the walnut halves and serve in generous slices.
I put the all the butter cream on the top and didn't decorate with walnuts, it might have been better if I did. It was still good though!
