directions

Preheat your oven to 350°F (175°C). Grease and line a 9-inch springform pan with parchment paper.

In a saucepan over medium heat, combine the Guinness and butter. Stir until the butter is melted.

Remove from heat and whisk in cocoa powder and sugar until smooth.

In a small bowl, whisk together sour cream, eggs, and vanilla extract.

Slowly add the sour cream mixture into the Guinness-chocolate mixture, stirring until combined.

In a separate bowl, whisk together flour, baking soda, and salt.

Fold the dry ingredients into the wet mixture and mix until just incorporated.

Pour the batter into the prepared pan and smooth the top.

Bake for 45–55 minutes, or until a toothpick inserted in the center comes out clean.

Cool completely in the pan on a wire rack before frosting.

For the frosting, beat cream cheese until smooth. Add powdered sugar gradually, then mix in heavy cream and vanilla until light and fluffy.

Spread or pipe the frosting over the cooled cake to resemble a foamy pint.

FAQs

Does the cake taste like beer?

Not exactly. The Guinness deepens the chocolate flavor but the beer taste is subtle.

Can I use another stout?

Yes, any dark stout will work, but Guinness provides the classic profile.

Can I skip the beer?

It’s essential for this recipe’s unique flavor, but for a non-alcoholic version, substitute with strong coffee or milk and add a bit of vinegar.

Is the alcohol cooked out?

Most of it bakes out, but for full removal, ensure the cake is baked thoroughly.

Can I make it gluten-free?

Yes, use a 1:1 gluten-free flour blend in place of all-purpose flour.

What kind of cocoa is best?

Use unsweetened natural or Dutch-process cocoa for a rich flavor.

Can I make this ahead?

Yes, it tastes even better the next day. Bake and frost ahead, then chill.

Is the frosting optional?

Technically, yes—but it’s highly recommended for contrast and presentation.

Can I use this batter for cupcakes?

Absolutely. Bake for 18–22 minutes and check with a toothpick.

How do I store leftovers?
