Why is this chocolate cake also called an Irish Car Bomb Cake?
If you and your family are not big drinkers, you might not know that there is a popular drink by the same name. It’s made by filling a shot glass with Jameson Irish whiskey and a shot of Baileys Irish Cream and dropping it into a pint glass of Guinness Stout Beer. The shot glass makes a little “explosion” when dropped into the beer, spawning the name. It’s a bit controversial as it references some Irish history. Hence the name I’ve given it or feel free to call it an Irish Whiskey Cake if you’d like!
Will the alcohol bake out of this Chocolate Guinness Cake?
Although some of the alcohol in this cake recipe cooks off during the baking process, a decent percentage remains, somewhere between 25-35%. Individuals in recovery, pregnant women or breastfeeding, and those who choose not to drink for religious, health, or other reasons might want to avoid this cake.
It should also go without saying that it’s a dessert made especially for the adults, so please don’t feed it to children or those under 21.
This cake has three major parts you’ll need ingredients for, the batter, the ganache, and the frosting.
Cake Batter Ingredients
- 2 ½ cups all-purpose flour
- 1 teaspoon baking powder
- 1 cup unsalted butter
- 1 cup of Guinness Stout Beer
- 1 cup of sour cream
- 1 ½ cups white sugar
- 1 ½ teaspoon salt
- ¾ cup of unsweetened cocoa powder
- 2 large eggs
Chocolate Ganache Ingredients
- 3 ounces dark chocolate chips
- 3 ounces semisweet chocolate chips – For more dark chocolate flavor, use all dark chocolate chips. You could also substitute milk chocolate chips for either dark or semisweet ones.
- 2 tablespoons melted butter
- ½ cup heavy cream
- 3 tablespoons Jameson Irish whiskey
Bailey’s Cream Frosting Ingredients
- 4 cups of powdered sugar (more if needed)
- 1 cup of butter
- 6 tablespoons of Bailey’s Irish Cream Liqueur
How to make Chocolate Stout Bundt Cake
- Prepare: Preheat the oven to 350 degrees F. Grease a 12-cup bundt pan and then dust it with flour, ensuring it gets into all the ridges. Set aside.
- Make the Ganache: Combine butter and chocolate chips in a microwave-safe bowl, then melt in the microwave in 20-second intervals, stirring in between. Pour heavy cream into a saucepan and bring it to a boil. Pour the chocolate mixture in but don’t stir. Let it sit for about two minutes, then add whiskey and stir to combine.
- Put the ganache in the fridge for 5 minutes, then stir. Continue stirring every five minutes until the mixture becomes cool but not solid.
- Make the Stout Cake Batter: Bring beer and butter to a simmer in a medium saucepan over medium heat. Whisk in the 3/4 cup cocoa powder, then remove the saucepan from the heat and let the mixture cool.
- Put the flour, sugar, baking powder, and salt in a large mixing bowl. Add eggs and sour cream and beat until just combined. Add in the cooled beer mixture and beat on low speed.
- Add ½ of the batter to the prepared bundt pan, then ganache, and finally, add the rest of the batter. Bake for 40-50 minutes in the preheated oven until a toothpick inserted near the center comes out clean. Bundt cakes take a little extra time to bake than regular cake pans. Allow the cake to cool completely.
- Make the frosting: Whip butter and powdered sugar one cup at a time. Add in Bailey’s. If the frosting becomes too liquid, add more powdered sugar as needed, but only a tablespoon or so at a time. When the cake is cool, frost it, cover with chocolate shavings, if desired, and enjoy it with a tall glass of milk!
Tips for a Successful Bundt Cake
- A frosted cake like this can be stored covered at room temperature for 4-5 days. Use a cake keeper or large overturned bowl to cover the cake.
- Once you cut the cake, moisture begins to escape, and the cake starts to grow stale. You can cover the sliced sides with a piece of plastic wrap to help slow this process. Continue to keep it covered.
- Don’t use butter to grease your pan- this can actually cause your cake to stick to the pan! Use shortening or oil, then sprinkle flour in the pan and distribute it evenly.
- Remember to grease the center tube of the bundt cake pans!
- Let the cake cool in the pan on a wire rack for about 10-20 minutes. Tap and gently shake the pan to help loosen the cake. Then carefully slide a table knife down the sides to release any sticking spots. Invert the pan over the cooling rack, remove it, and let the cake continue to cool on the rack.

Do I need to refrigerate this cake?
Most cakes are fine to store at room temperature for a few days. You only need to refrigerate this if you have a hot and humid kitchen or if you won’t be serving it for a few days.
Can a chocolate bundt cake be frozen?
