Chocolate beer cake may sound like an unusual combination, but trust me, it's a match made in dessert heaven. The Guinness adds richness to the chocolate cake, and the beer's carbonation helps create a light and airy texture. So tasty!
Ingredients

This easy Guinness Chocolate Cake starts with a devil’s food cake mix and instant chocolate pudding for rich, chocolatey flavor. Guinness stout beer adds deep, bold notes, while butter, eggs, pure vanilla extract, and a pinch of salt create a tender crumb.
A big scoop of sour cream keeps the cake extra moist. Top it off with creamy store-bought sour cream frosting and a handful of sprinkles for a fun, festive finish!

Frequently asked questions (FAQ’s)
When alcohol is baked in a cake, most of it evaporates during the baking process due to the high heat, leaving behind only the flavor.
Absolutely, this cake can be made up to 24 hours in advance. In fact, it's best if it's made the day before. Making it perfect for potluck's and celebrations!
Beer gives the cake a lighter texture, carbonation, and subtle flavor. It also adds moisture to the batter, resulting in a deliciously moist and fluffy cake! You'll love this one!
Variations
Swap the Guinness for another stout beer, like a chocolate or coffee stout. Or mix in dark chocolate chips or chunks to the batter for extra bursts of chocolate in every bite!
Brush the top of the cake with Baileys Irish Cream right when it comes out of the oven. The cake will be even more rich and decadent.
Try using a cream cheese frosting or sour cream frosting instead of vanilla frosting for a tangy twist that pairs beautifully with the deep, chocolatey cake.

Deb’s top tips
When it comes to making cakes, the most crucial factor is not overmixing. You want to mix your batter until just combined, never longer than 2 minutes.
- I used store-bought frosting to save time. However, you can also use your favorite homemade frosting recipe instead.
- If you want to add some extra flair to your cake, a drizzle of caramel sauce or even some chocolate shavings or curls are great garnishes.
