Ingredients needed
Aside from the Irish beverages, this Guinness chocolate cake is made from pantry staples. This is what you’ll need:

Does Guinness chocolate cake taste like beer?
Guinness and dark stouts are often described as having chocolate-y undertones, so while the combination of beer and chocolate might sound a bit far-fetched at first, the pairing works well! The Guinness complements the chocolate, adding a deep, complex flavor without overpowering the chocolate. The dark, malty flavor of Guinness enhances the chocolate flavor in the cake, making it richer and more intense. Even if you don’t like beer, you’ll love this cake! The Guinness boils, reducing, and the caramel and chocolate notes intensify. The Guinness keeps the cake moist, omitting the need to add eggs.
Tips for making Guinness chocolate cake
This recipe is practically foolproof, but a few handy tips can elevate your baking game, leaving you with a moist cake with rich chocolate flavor. Here’s what to keep in mind:
- Temperature: Aside from the Guinness that you’ll boil, let all of the other ingredients reach room temperature before you start baking. This helps ensure even mixing and a smoother batter.
- Mixing: Be mindful not to over mix your batter as it can make your cake too dense.
- Boil: Once the beer starts boiling, it’ll get really foamy. To make sure it doesn’t boil over, opt for a pot that’s bigger than you’d usually reach for.
- Measure : You’ve heard it before and you’ll hear it again: baking is a science! Measure carefully whenever you’re baking to set yourself up for success.
