Guinness Chocolate Cake Ingredients
For the Cake:
Guinness stout (1 cup) — Use Guinness Draught for that rich, deep flavor; other stouts just won’t cut it.
unsalted butter (1/2 cup) — Always use unsalted butter; else you’ll throw off the cake’s balance with too much salt.
granulated sugar (1 3/4 cups) — Don’t skimp on sugar; it’s key for sweetness and moisture, or your cake’ll be dry.
unsweetened cocoa powder (3/4 cup) — Get good quality cocoa, like Ghirardelli; cheap stuff’ll make your cake taste bitter.
baking soda (1 1/2 teaspoons) — Don’t skip the baking soda; it’s crucial for lift, or your cake’ll come out dense.
salt (1 teaspoon) — Use kosher salt, but don’t overdo it; too much makes it taste salty, not balanced.
eggs (2 large) — Room temp eggs mix better; cold ones’ll leave you with a lumpy batter.
buttermilk (1 cup) — Use real buttermilk; substitutes won’t give that creamy tang, and the cake’ll fall flat.
vanilla extract (2 teaspoons) — Use pure vanilla extract, not imitation; otherwise, you’ll miss that warm, rich flavor.
For the Frosting:
cream cheese (8 ounces) — Go for full-fat cream cheese; low-fat won’t whip up right and ruins the frosting.
unsalted butter (1/2 cup) — Sift powdered sugar for a smooth frosting; otherwise, you’ll end up with lumps.
powdered sugar (3 cups) — Use heavy cream for whipping; anything lighter won’t hold up and will be runny.
heavy cream (1/4 cup)
vanilla extract (1 teaspoon)

How to Make Guinness Chocolate Cake
1. Preheat and Prepare: Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking pan. You want it ready for that sticky-sweet batter.
2. Melt and Combine: In a large saucepan, combine the Guinness stout and unsalted butter. Heat over medium until the butter’s melted, then take it off the heat. You’ll smell that rich, malty aroma.
3. Mix Dry Ingredients: Whisk in the granulated sugar, unsweetened cocoa powder, baking soda, and salt until everything’s well blended. Look for a smooth, glossy mix—no lumps here!
4. Whisk Wet Ingredients: In another bowl, whisk together the eggs, buttermilk, and vanilla extract. Once that’s smooth, stir this into the Guinness mixture until combined (but don’t overmix!).
5. Add Batter to Pan: Pour the batter into your prepared pan and smooth out the top. Bake for 30-35 minutes or until a toothpick comes out clean—don’t rush this part! (Trust me, it’ll be worth it.)
6. Cool Time: Let the cake cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely. Keep an eye on it; if you leave it too long in the pan, it’ll get stuck!
7. Frosting Prep: While it’s cooling, beat together softened cream cheese and unsalted butter in a bowl until creamy. Gradually add powdered sugar, then mix in heavy cream and vanilla extract until fluffy.

How to Store Guinness Chocolate Cake
- Room Temperature: Keep it in an airtight container for up to 3 days. It’ll stay moist, but the frosting might get a bit soft.
- Refrigerator: Store it in the fridge for about a week, wrapped tightly or in a sealed container. Just know that the frosting can lose some of its fluffiness.
- Freezer: Wrap slices tightly in plastic wrap and foil, then pop them in a freezer-safe bag for up to 3 months. It still tastes great when thawed, but the texture might change just a bit.
- Reheating: If you want to enjoy it warm, microwave a slice for about 15 seconds until it’s just warm (you’ll smell that chocolate goodness!). Avoid overheating or it’ll dry out.
What to Serve with Guinness Chocolate Cake?
It’s rich and dense enough to stand on its own, but adding a few sides can lighten it up and add some fun contrast.
- Vanilla Ice Cream: Cold creaminess balances the cake’s richness, giving you that melty-gooey vibe in every bite.
- Fresh Raspberries: Their tartness cuts through the sweetness, brightening each forkful with a punch of flavor.
- Whipped Cream: Light and airy, it adds a fluffy texture that contrasts beautifully with the dense cake. (You can whip it up in about 5 minutes.)
- Chocolate-Covered Pretzels: The salty crunch gives a nice texture difference, plus they’re super easy to grab and munch on!
- Espresso or Coffee: A hot cup complements the chocolate flavors and brings out the richness without overwhelming sweetness.
- Citrus Sorbet: The cold temp and acidity refresh your palate after each indulgent bite — try making it ahead for convenience!
- Caramel Sauce: Drizzling this sticky-sweet goodness adds another layer of flavor while enhancing that fork-tender texture.
Guinness Chocolate Cake Variations
Here’s how to play with this recipe and make it your own.
- Coffee Kick: Add 1 tablespoon of instant coffee granules with the cocoa powder for a richer chocolate flavor.
- Minty Freshness: Stir in 1 teaspoon of peppermint extract when mixing the eggs and buttermilk for a festive twist.
- Choco-Coffee Frosting: Blend in 2 tablespoons of brewed coffee into the cream cheese frosting for an extra depth.
- Nutty Crunch: Fold in 1/2 cup of chopped walnuts into the batter right before pouring it into the pan.
- Gluten-Free Option: Swap out regular flour with a gluten-free all-purpose blend (just use the same amount!).
- Next Level: Drizzle some melted dark chocolate over the frosting for a melty-gooey finish that’s hard to resist.
Make Ahead Options for Guinness Chocolate Cake
I like to prep the Guinness Chocolate Cake a day ahead when I can. I’ll bake the cake, let it cool, and then wrap it tightly in plastic wrap before storing it in an airtight container at room temperature. It holds up well for about three days, but the frosting? That’s best made fresh right before serving. Just whip together that cream cheese frosting and spread it over the cooled cake when you’re ready to dig in. (Trust me on this: the texture of freshly frosted cake is way better.) Just remember, the cake stays moist while the frosting can lose its fluffiness if stored too long. Enjoy every bite!
Guinness Chocolate Cake Recipe FAQs
Can I use a different stout for the Guinness Chocolate Cake?
You really want to stick with Guinness Draught for that rich, deep flavor. Other stouts just don’t have the same profile, and they could change how the cake tastes. (Trust me on this.) If you can’t find Guinness, look for a similar dry stout, but know it might not hit those sweet notes quite right. Always go for quality to keep your cake on point.
What’s the best way to store this dish?
Once your cake’s frosted and cooled completely, cover it with plastic wrap or store it in an airtight container at room temperature. It should stay fresh for about 3 days. If you want to keep it longer, pop it in the fridge for up to a week. Just remember that cold storage can make the frosting a bit firmer, so let it sit out a bit before serving!
Why did my cake turn out dense?
If your Guinness Chocolate Cake came out dense, you might’ve skipped the baking soda or overmixed the batter. Both can mess with that light texture we’re going for. When combining wet and dry ingredients, mix until just combined—no lumps means you’re good! You should also check that your baking powder’s fresh; old leavening agents won’t give you that lift you need.
Can I make this recipe ahead of time?
Absolutely! You can bake the cake a day or two in advance and store it covered at room temperature (just don’t frost it until you’re ready to serve). This dish gets even better as it sits because those flavors meld together beautifully! Just ensure it’s completely cool before wrapping it up; otherwise, you’ll end up with soggy spots—nobody wants that!
Final Thoughts on Guinness Chocolate Cake
This Guinness Chocolate Cake is all about that rich, deep flavor from the stout. Seriously, using Guinness Draught instead of another stout makes a world of difference in taste. If you’ve been putting this off, tonight’s the night. Bake it up, frost it with that creamy cream cheese frosting, and watch it disappear faster than you can say “chocolate cake.” Drop a comment if you added anything or tried a twist — I’m always curious to hear how yours turned out!
