Chocolate Guinness® Cake
This Chocolate Guinness Cake is a rich, dark dessert combining stout beer, cocoa and sour cream, topped with a silky cream cheese frosting. The Thermomix melts the butter gently, blends the batter evenly and whips double cream into a velvety topping, making this Irish-inspired classic straightforward to prepare with consistently excellent results every time.
About this recipe
Chocolate Guinness Cake with the Thermomix TM7 is one of those dessert recipes that reliably impresses guests while staying surprisingly simple to make. The dark stout combines with cocoa powder and sour cream to create an intensely moist crumb with a deep, almost savoury chocolate character, finished with a cloud of cream cheese and double cream frosting. Why does this cake work so well in the all-in-one kitchen machine? First, the gentle melting function warms the butter and Guinness together without any risk of scorching, something that often goes wrong in a pan on the hob. Second, the mixing function blends eggs, flour and caster sugar into a perfectly even batter in well under a minute, eliminating lumps of cocoa by hand. Ideal for birthdays, St Patrick's Day celebrations or a weekend baking project, this showstopper dessert delivers bakery-quality results with everyday ingredients.
Preparation tips
- Make sure the Guinness has lost most of its fizz before adding it to the batter, as excess foam can alter the texture. Let the melted butter and stout mixture cool slightly before incorporating the eggs so they do not scramble in the bowl.
- For the cream cheese frosting, use full-fat cream cheese straight from the fridge and beat it briefly before adding the double cream. Spread the frosting only once the cake is completely cool, otherwise it will slide off the sides.
- Store leftover cake in an airtight container in the fridge for up to three days; the flavour actually improves overnight as the stout soaks into the crumb. Bring a slice to room temperature before serving for the best texture.
Recipe variations
- Lactose-free version: replace the sour cream with a lactose-free alternative and use plant-based cream cheese and whipping cream for the frosting. The Guinness itself is naturally lactose-free, so the dark, moist character of the cake remains untouched.
- Festive version: add a teaspoon of orange zest to the batter and decorate the frosting with grated dark chocolate and a dusting of cocoa for Christmas. A dash of espresso powder in the batter also intensifies the chocolate flavour beautifully.
Thermomix TM7 Benefits
- Gentle heating melts the butter with the Guinness in the TM7 without scorching, giving a smooth liquid base for the chocolate cake batter.
- With the TM7 mixing function, eggs, flour and cocoa blend into a lump-free cake batter in seconds, saving kneading effort by hand.
- Weighing the caster sugar and plain flour directly in the TM7 bowl ensures precise proportions for a moist, evenly risen Guinness cake.
- The TM7 whips the double cream and cream cheese into a silky frosting with stable peaks, far quicker than an electric hand whisk.
- Grinding any lumpy cocoa powder in the TM7 before mixing guarantees a fine, even texture throughout this rich chocolate stout cake.
