Ingredients

FAQs
Can I taste the beer in the cake?
The Guinness adds depth and moisture but doesn’t make the cake taste like beer—it enhances the chocolate flavor subtly.
Can I use a different stout beer?
Yes, any dark stout or porter will work, but Guinness is traditional for its unique flavor profile.
Is the alcohol still present after baking?
Most of the alcohol bakes off, but if you’re concerned, you can use a non-alcoholic stout.
Can I make this cake without beer?
You can substitute brewed coffee for a similar deep flavor, though it won’t be exactly the same.
What type of cocoa powder should I use?
Use unsweetened natural or Dutch-processed cocoa for the best rich chocolate flavor.
Do I need a springform pan?
A springform pan is ideal for easy removal, but you can use a regular cake pan lined with parchment.

It should be thick but spreadable, resembling the foamy head of a pint of Guinness.
Can I make this cake ahead of time?
Yes, it actually tastes better the next day once the flavors have had time to meld.
What should I serve with Chocolate Guinness Cake?
It pairs wonderfully with coffee, Irish cream, or even a cold glass of milk.
