  1. In a medium bowl, beat the butter and sugar together until light and fluffy. Gradually add the eggs followed by the flour and instant coffee. Stir most of the walnuts (if using) into the batter, reserving a few for decoration. Transfer to a microwave-proof dish and cook on full power for 2 mins. Reduce the power to medium and cook for 2 mins.
  2. After 4 mins, check to see if the cake is cooked – it should be risen and spring back when touched. If it needs a bit longer, cook on medium for 1 min more at a time, checking after each minute until the cake is cooked. Remove and allow to cool.
  3. Meanwhile, make the coffee butter cream. Dissolve the coffee in the milk, then add the butter and icing sugar. Beat until smooth, spread over the cake and top with the reserved walnuts.

cake is a little dry but the frosting makes up for it. it is good but Im not sure why you need to make a cake in the microwave as the prepping part is the same amount of effort as a regular basic cake

I wrote detailed feedback on this recipe but BBC site 'encountered an issue' and I lost it so here's the brief version:
Icing- delicious. But double recipe amount.
Cake- bland and dry. Saved by icing

Overall easy to make and good to do with kids.

I made this without the walnuts but did make more topping and it was lovely. Made it in a round perspex bowl and it turned out fine (with no greasing) and I iced the top and you would hardly know it was microwaved!!

I made this cake on the same day I got the new magazine! It was quick and easy to make - you can always add more coffee for a stronger taste. The family all enjoyed it and I will definitely be making it again!
