Welcome to a recipe that’s as delightful to make as it is to eat. There’s a special magic that happens when rich, dark Guinness stout meets chocolate in a cake batter. The deep, malty character of the beer wonderfully enhances the cocoa, adding incredible depth and a hint of coffee-like flavor. It also guarantees an exceptionally moist crumb that makes every bite a true indulgence. This Chocolate Guinness Cake, crowned with a tangy cream cheese frosting, strikes the perfect balance between rich and refreshing. It’s a showstopper for St. Patrick’s Day but is far too delicious to save for just one day a year. Let’s get baking!

Ingredients
For the Chocolate Guinness Cake
- 250ml Guinness stout
- 250g unsalted butter, cubed
- 80g unsweetened cocoa powder, sifted
- 400g granulated sugar
- 150ml soured cream
- 2 large eggs
- 1 tbsp vanilla extract
- 275g all-purpose flour
- 2 ½ tsp baking soda
- ½ tsp salt
For the Cream Cheese Frosting
- 300g full-fat cream cheese, cold
- 125g unsalted butter, at room temperature
- 150g powdered sugar, sifted
- 1 tsp vanilla extract
Instructions
- Prepare the Pan and Oven: Preheat your oven to 180°C (160°C fan/350°F/Gas 4). Grease a 23cm (9-inch) springform cake tin and line the bottom with parchment paper.
- Melt Butter and Guinness: In a large saucepan, gently heat the Guinness and butter over medium-low heat until the butter has completely melted. Do not let it boil. Remove from the heat.
- Add Cocoa and Sugar: Whisk the sifted cocoa powder and granulated sugar into the warm Guinness mixture until you have a smooth, dark liquid. Set aside to cool slightly.
- Combine Wet Ingredients: In a separate bowl, whisk together the soured cream, eggs, and vanilla extract.
- Mix the Batter: Pour the soured cream mixture into the saucepan with the Guinness and chocolate mixture. Whisk until everything is well combined.
- Add Dry Ingredients: In a large mixing bowl, whisk together the flour, baking soda, and salt. Pour the wet ingredients into the dry ingredients and whisk gently until just combined. Be careful not to overmix; a few small lumps are okay.
- Bake the Cake: Pour the batter into your prepared cake tin. Bake for 45-60 minutes, or until a skewer inserted into the center comes out clean.
- Cool Completely: Let the cake cool in the tin for about 15 minutes before removing it to a wire rack to cool completely. It’s essential the cake is fully cool before frosting.
- Make the Frosting: While the cake cools, prepare the frosting. In a large bowl, beat the softened butter with an electric mixer until light and fluffy. Add the cold cream cheese and beat again until smooth. Gradually add the sifted powdered sugar and vanilla, mixing on low speed until combined, then on high until the frosting is thick and creamy.
- Frost and Serve: Once the cake is completely cool, spread the cream cheese frosting generously over the top, creating swirls with the back of a spoon. For a clean slice, chill the cake for 30 minutes before serving.
