This moist and decadent cake combines the rich bitterness of dark chocolate with the smoky depth of Guinness beer, creating a complex flavor profile. The batter is mixed with melted chocolate and Guinness, baked until tender, and topped with a tangy cream cheese frosting, resulting in a visually appealing, fudgy dessert with a tender crumb.
Preheat your oven to 180°C (350°F). Grease and flour a 23cm (9-inch) springform pan to prevent sticking.
Chop the dark chocolate finely and melt it together with the Guinness in a heavy-bottomed saucepan over low heat, stirring until smooth and glossy. This fragrant mixture will smell rich and chocolatey.
In a large mixing bowl, beat the softened butter and sugar with an electric mixer until the mixture is light, fluffy, and slightly pale, about 3-4 minutes. This aerates the batter for a tender crumb.
Add the eggs one at a time, beating well after each addition. The mixture should become smooth and silky, with a slight sheen.
Stir in the vanilla extract. Then, fold in the melted chocolate and Guinness mixture gently, just until combined. The batter will be a deep, glossy chocolate color.
Sift together the flour, baking powder, baking soda, and salt. Gently fold these dry ingredients into the wet batter, being careful not to overmix. The batter should be thick but pourable.
Pour the batter into the prepared springform pan and smooth the top with an offset spatula. Tap the pan lightly on the counter to release air bubbles.
Bake in the preheated oven for 45-50 minutes, or until a skewer inserted into the center comes out with moist crumbs—this indicates the cake is perfectly baked.
Remove the cake from the oven and let it cool in the pan for 15 minutes. Then, carefully transfer it to a wire cooling rack and let it cool completely before frosting.
For the frosting, beat the softened cream cheese, powdered sugar, and a splash of Guinness together until fluffy and creamy—about 2-3 minutes. This tangy frosting balances the rich chocolate flavor beautifully.
Spread the cream cheese frosting evenly over the cooled cake using an offset spatula. Decorate with chocolate shavings or drizzled caramel if desired for an extra indulgent touch.
Slice, serve, and enjoy this luscious, fudgy Guinness chocolate cake that’s perfect for special occasions or cozy weekends.
Notes
Make sure to cool the cake completely before frosting to prevent melting. For a richer flavor, let the cake sit overnight before serving.
