Chocolate Guinness Cake: A Personal Favorite
Why Chocolate Guinness Cake Stands Out
Hi, I’m Carry and welcome to my kitchen corner of the internet. I still remember the first time I baked a Chocolate Guinness Cake. It was a rainy Sunday in Texas, and I was craving something bold and indulgent. On a whim, I grabbed a couple of bottles of Guinness from the fridge. That decision changed the way I looked at chocolate cake forever.
Guinness may sound like an odd choice for baking, but trust me it elevates chocolate cake into something extraordinary. The result is a moist, dense crumb with deep cocoa notes and a subtle bitterness that balances the sweetness perfectly. It’s not just a cake; it’s an experience.
If you’ve enjoyed rich desserts like this Chocolate Cake Mix Brownies or indulgent Air Fryer Chocolate Cupcakes, you’ll love this elevated twist. The recipe is straightforward and forgiving, so even beginner bakers can tackle it with confidence.
A Rich, Deep Flavor That Surprises
So, what exactly does Chocolate Guinness Cake taste like? Imagine the smooth bitterness of dark chocolate paired with a whisper of coffee and malt. Guinness brings depth without overpowering. The beer’s natural roastiness enhances cocoa’s flavor, making every bite complex and satisfying.
It’s a cake that works equally well for casual get-togethers and elegant dinner parties. Pair it with cream cheese frosting for contrast or enjoy it plain with a dusting of powdered sugar. In fact, it’s now a staple at my family reunions alongside my mom’s peach cobbler.
If you love experimenting with unique flavor combos like those in this Chocolate Cake Mix Waffles or Chocolate Cake Mix with Sour Cream, this Guinness-infused cake is a must-try.

Baking Time and Techniques
Follow these easy steps to ensure your Chocolate Guinness Cake turns out perfectly every time:
- Prepare the beer reduction: Pour both bottles of Guinness into a saucepan. Simmer over medium heat until reduced to about 1 1/4 cups (300ml). Reserve 3 tbsp for the frosting. Cool the rest to room temperature.
- Preheat the oven: Heat your oven to 350°F (177°C). Grease and line two 9-inch round cake pans with parchment paper.
- Mix dry ingredients: In a large bowl, whisk flour, cocoa powder, sugar, baking soda, baking powder, salt, and espresso powder.
- Combine wet ingredients: In another bowl, whisk the cooled reduced Guinness, oil, sour cream, eggs, vanilla, and buttermilk until smooth.
- Create the batter: Gradually mix wet ingredients into the dry, stirring gently until combined. The batter will be thin—this is normal.
- Bake: Divide the batter evenly between the pans. Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
- Cool: Let cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
Frosting Instructions:
- Beat cream cheese and butter until creamy.
- Gradually add confectioners’ sugar and cocoa powder.
- Mix in reduced Guinness and a pinch of salt.
- Frost cooled cake as desired and garnish with gold sprinkles.


Enjoying and Storing Chocolate Guinness Cake
Serving Suggestions
One of the best parts of baking Chocolate Guinness Cake is deciding how to serve it. I often bring this cake to casual gatherings and brunches it always turns heads. Personally, I love serving thick slices with a dollop of freshly whipped cream or a scoop of vanilla bean ice cream. The contrast of the cold, creamy topping with the rich, warm cake is heavenly.
For brunch, pair the cake with strong coffee or, if you’re feeling indulgent, an Irish coffee for a fun themed spread. Fresh berries like raspberries or strawberries add a bright, tart note that balances the deep chocolate. This cake also pairs beautifully with other chocolate-forward desserts try it alongside Chocolate Crinkle Cookies with Cake Mix or as part of a layered dessert bar featuring treats like Royal Purple Velvet Cake.
I always suggest slicing the cake with a hot knife for clean cuts and wiping the blade between slices to showcase that luscious texture.
Storing and Freezing Tips
Proper storage ensures your Chocolate Guinness Cake stays delicious for days. Store leftover cake in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate for up to 5 days. If refrigerated, allow slices to come to room temperature before serving to restore the best texture.
This cake also freezes exceptionally well. Wrap individual slices in plastic wrap, then foil, and freeze for up to 3 months. To serve, thaw overnight in the refrigerator or at room temperature for a few hours.
Following these tips ensures that whether you’re savoring the last slice or preparing in advance for an event, your Chocolate Guinness Cake will taste just as good as the first bite.
