Thu, 8 October 2026

Ingredients For the cake

* 260g butter

* 300ml Guinness, stout, or non-alcoholic stout

* 100g cocoa powder

* 2 eggs

* 420g caster sugar

* 2 tsp vanilla extract

* 180ml buttermilk

* 300g plain flour

* 2 tsp bicarbonate of soda

* 1 tsp baking powder For the icing

* 300g icing sugar, sifted

* 340g cream cheese

Method

1. Get the oven on first Preheat your oven to 170°C / 325°F / Gas Mark 3. Line the base of a 30cm springform cake tin with baking parchment. 1. Make that lovely Guinness chocolate mixture Melt the butter in a saucepan over a medium heat. Once melted, pour in the Guinness and give it a good stir. Take the saucepan off the heat and whisk in the cocoa powder until smooth and glossy.

2. Bring the wet ingredients together In a large mixing bowl, whisk the eggs, caster sugar, vanilla and buttermilk until nicely combined. Slowly pour in your warm Guinness mixture, whisking as you go.

3. Add the dry ingredients Sift in the flour, bicarbonate of soda and baking powder. Give everything a good whisk until you have a smooth cake batter. Don’t overwork it — just make sure there are no pockets of flour.

4. Into the oven Pour the batter into your prepared tin and pop it into the oven for around 55 minutes. To check it’s ready, insert a dry skewer into the centre. If it comes out clean, you’re good to go. Let the cake cool in the tin for a little while, then carefully remove it and leave it to cool completely on a wire rack.

5. Whip up the icing While the cake is cooling, put the sifted icing sugar and cream cheese into a bowl. Using an electric whisk, beat until light, smooth and fluffy.

6. Finish it off Once your cake is completely cool, transfer it to a serving plate and generously spread that gorgeous cream-cheese icing over the top. Then all that’s left to do is slice, serve and enjoy!
