Step 1: Prep Oven and Tin 🍺

Preheat your oven to 180°C (160°C Fan / Gas Mark 4). Grease a 23cm (9in) springform cake tin and line the base and sides with baking parchment paper.

Step 2: Melt Stout, Butter, and Cocoa 🥣

In a large saucepan over medium-low heat, pour in the 250ml Guinness and add the cubed butter. Heat gently until the butter completely melts. Whisk in the sifted cocoa powder and dark soft brown sugar until smooth and silky. Remove from heat and allow to cool slightly for 5 minutes.

Step 3: Whisk Batter and Add Dry Ingredients 🌾

In a separate bowl, whisk together the beaten eggs, sour cream, and vanilla extract. Pour this into the warm Guinness mixture and whisk until well combined. Sift the plain flour and bicarbonate of soda over the liquid base, then fold gently until you have a smooth, dark batter.

Step 4: Bake to Fudgy Perfection 🍰

Pour the liquid batter into your prepared tin. Bake on the middle shelf of your preheated oven for 45 to 55 minutes. The cake is ready when a wooden skewer inserted into the center comes out clean or with a few moist crumbs attached. Cool completely in the tin on a wire rack.

Step 5: Whip Silky Cream Cheese Frosting 🧁

Beat the cream cheese and sifted icing sugar together until smooth. In a separate bowl, whip the double cream until soft peaks form, then gently fold it into the cream cheese mixture until thick, fluffy, and spreadable.

Step 6: Frost and Serve 🎨

Transfer the cooled chocolate cake onto a serving plate. Spoon the fluffy cream cheese frosting onto the top of the cake, swirling it gently with an offset spatula to resemble the frothy head of a freshly poured pint of Guinness!

🤫 Cook’s Secrets for Flawless Guinness Cake

Even with a simple recipe, a few professional tricks can elevate your cake to bakery-quality standard:

1. 🍺 Don’t Worry About Beer Taste: The alcohol bakes off in the oven, leaving behind a rich, malty, caramel background note that makes dark chocolate taste twice as deep.
2. 🧀 Use Full-Fat Cream Cheese: Always use full-fat block-style cream cheese. Low-fat variants contain excess water, causing frosting to turn runny and liquid.
3. 🧊 Cool Cake Completely Before Frosting: Never spread cream cheese frosting over a warm sponge! Residual heat will melt the frosting into a sugary puddle.
4. 🥣 Don’t Over-Mix Batter: Fold the flour gently until just combined. Over-mixing activates gluten, resulting in a tough cake rather than a soft, fudgy crumb.

❓ Frequently Asked Questions

Does Mary Berry Guinness cake contain alcohol after baking?

No! Almost all of the alcohol content evaporates during the 50-minute bake, leaving behind only the deep malty flavor and rich moisture.

Can I bake this cake in advance?

Yes! The un-frosted sponge tastes even better when made 1 day in advance. Wrap tightly in cling film and store at room temperature, then frost on the day of serving.

How should I store leftover Guinness cake?

Because of the cream cheese frosting, store leftover cake in an airtight container in the fridge for up to 4 days. Let slices sit at room temperature for 15 minutes before serving for best texture.

Can I freeze Guinness cake?

You can freeze the un-frosted sponge wrapped in baking parchment and foil for up to 3 months. Thaw at room temperature and top with fresh frosting before serving.
