Chocolate Coffee Stout Cake

I have long been a fan of Nigella's Chocolate Guinness cake and as soon as I tasted Roaster Coaster coffee stout - a limited edition collaboration between Brewdog and Evil Twin, I knew I had to make a version of this cake with the coffee stout in place.

Chilled and poured, it's velvety and smooth, like a coffee stout milkshake. Replacing the Guinness in the cake, it makes for a damp chocolate cake with real coffee depth and complexity. 

**I feel compelled at this point to note that this is not a sponsored post - I'm just an indie ale/stout fan!**


For the cake

250ml Roaster Coaster stout by Brewdog vs Evil Twin (available at Tesco)

250g unsalted butter

75g cocoa powder

400g caster sugar

150ml sour cream

2 large eggs

1 tblsp vanilla extract

275g plain flour

2½ tsp bicarbonate of soda

 For the frosting

300g cream cheese 

150g icing sugar

2 tsp cornflour

125ml double cream

  1. Preheat the oven to 180 centigrade/ gas mark 4, then butter and line a 23cm / 9 inch spring-form tin.
  2. Pour the stout into a large wide saucepan, add the butter and gently heat until it melts, at which time you should whisk in the cocoa and sugar.
  3. Beat the sour cream with the eggs and vanilla and then pour into the glossy brown liquid and finally whisk in the flour and bicarb.
  4. Pour the cake batter into the greased and lined tin and bake for 45 minutes to an hour. Leave to cool completely in the tin on a cooling rack, as it is quite a damp cake.
  5. When the cake's cold, carefully release it from its tin and stand it on a cake plate or stand.
  6. Time to make the frosting!
  7. Sieve the icing sugar and cornflour together.
  8. Lightly beat the cream cheese in a bowl to remove any lumps, then sift over the sugar/cornflour mix and then beat to combine.
  9. Add the double cream and softly whip until you have thick, spreadable consistency. 
  10. Dollop over the top of the cake and spread it in soft swirls so that it resembles the frothy top on a pint of stout.
