Backstory: Why Bake with Guinness?
Pairing stout and chocolate may seem unusual at first, but the complexity of a dark ale, such as Guinness, enhances the natural bittersweet character of chocolate. This cake owes its mesmerizing depth in both flavor and color to this partnership. Many bakers return to this recipe for holidays, parties, and comfort baking alike, swearing by its crowd-pleasing powers and unique taste profile. Even the aroma is enticing: malty, toasty, and unmistakably chocolatey.
The Secret to a Moist, Irresistible Chocolate Cake
This recipe’s genius lies in its method and choice of ingredients. Sour cream provides tang and tenderness, while simmering the cocoa with stout ensures a pronounced chocolate flavor from the start. Baked in a bundt pan, the cake presents beautifully, ready to showcase the thick, shiny ganache that pools over its crown.
Ingredients
- Stout: 1 cup (such as Guinness, or another favorite dark stout)
- Unsalted Butter: 1 cup (2 sticks), plus more for greasing the pan
- Unsweetened Cocoa Powder: ¾ cup, Dutch-process preferred
- All-Purpose Flour: 2 cups
- Sugar: 2 cups
- Baking Soda: 1 ½ teaspoons
- Salt: ¾ teaspoon
- Eggs: 2 large
- Sour Cream: ⅔ cup
For the Ganache:
- Semi-sweet Chocolate: 6 ounces, finely chopped (quality chips or bars work well)
- Heavy Cream: ½ cup
- Instant Coffee or Espresso Powder: ¾ teaspoon
Step-by-Step Baking Instructions
Prepare the Cake
- Preheat and Prep: Preheat your oven to 350°F (175°C). Generously butter your bundt pan, ensuring you reach all corners for easy release after baking.
- Simmer Stout and Butter: In a heavy saucepan over medium heat, combine the stout and butter. Once the butter has melted, whisk in the cocoa powder until completely smooth. Remove from heat and let cool to just above room temperature; this step is essential to prevent scrambling eggs later.
- Combine Dry Ingredients: In a large bowl, whisk together the flour, sugar, baking soda, and salt. Set aside.
- Blend Wet Ingredients: Using an electric mixer, beat the eggs and sour cream in a large bowl until creamy, pale, and well combined (1–2 minutes).
- Mix in Chocolate: Gradually add the cooled stout-chocolate mixture to the egg-sour cream blend. Beat just until smooth and integrated.
- Add Dry Ingredients: Add the flour mixture to the wet ingredients. Beat on low until just combined; avoid overmixing to maintain a tender crumb. Finish folding the batter with a rubber spatula to ensure there are no dry pockets remaining.
- Bake: Scrape the thick, glossy batter into your prepared pan. Smooth the top for even baking. Bake in the center of the oven for about 35–40 minutes, or until a tester inserted in the center comes out clean (some ovens may require up to 45 minutes).
- Cool Completely: Once the cake is baked, transfer it to a rack and allow it to cool completely in the pan. This prevents sticking and helps the cake set, especially for intricate pans.
Make the Ganache
- Place the chopped chocolate, heavy cream, and instant coffee in the top of a double boiler set over gently simmering water. Melt everything together, stirring occasionally, until the mixture is velvety and all chocolate chunks are gone.
- Remove from heat and let cool just until slightly thickened, about 5 minutes. If you wait too long, the ganache will set and become difficult to pour.
- Turn the cooled cake out onto a rack set over parchment or a tray to catch drips. Spoon the warm ganache over the crown, letting it drip luxuriously down the sides. Use a spatula for gentle nudging if needed.
- Let the ganache set at room temperature before slicing and serving; the glaze will firm up to a glossy finish.
Expert Tips and Techniques
- Cooling Matters: Cool the cake completely in the pan before inverting. This crucial step minimizes sticking, especially with sticky or intricate pans.
- Use Quality Chocolate: The ganache is the crowning glory, so use the best chocolate you can find. Semi-sweet or bittersweet both work, depending on your taste for sweetness versus intensity.
- No Guinness? Most dark stouts substitute beautifully. Each imparts slightly different caramel or roasted notes.
- Room-Temperature Ingredients: Ensure eggs and sour cream are at room temperature before starting; this helps them blend smoothly and improves cake texture.
- To Freeze: The un-iced cake freezes well. Wrap tightly and freeze for up to a month, then thaw, glaze, and serve as fresh.
Serving and Storing Suggestions
This cake is substantial and decadent, needing little more than a cup of coffee or a glass of milk on the side. Though show-stopping for parties, it’s cozy enough to serve after dinner or as a weekend treat.
- Serving: Slice with a sharp serrated knife for clean cuts; the ganache can be sticky.
- Accompaniments: Lightly whipped cream, fresh berries, or even a scoop of vanilla ice cream turn this dessert into a celebratory finale.
- Storing: The cake keeps covered at room temperature for up to 3 days, or can be refrigerated for up to a week. Let return to room temperature before serving for best flavor and texture.
Frequently Asked Questions (FAQs)
Q: Can I make this cake without alcohol?
A: Yes. Replace the stout with an equal amount of strong brewed coffee or water for a similar moist crumb, though you will lose the malty undertones.
Q: Does the cake taste like beer?
A: The stout deepens the chocolate notes—it does not make the cake taste like beer. Most people notice a slight roasted complexity rather than overt bitterness or beer flavor.
Q: Can I bake this in a standard round or loaf pan?
A: Yes. Bake in two 8-inch rounds or a large loaf tin, adjusting baking time as necessary. Begin checking for doneness around 30 minutes for smaller pans.
Q: What kind of chocolate works best for the ganache?
A: Use good quality semi-sweet or bittersweet chocolate (60–70% cacao). Avoid overly sweet milk chocolate, as it can mask the complexity of the cake.
Q: Can I prepare the cake in advance?
A: Absolutely. The cake can be fully baked, cooled, and then wrapped tightly for up to two days before glazing. Ganache is best prepared and poured shortly before serving.
Creative Variations and Additions
- Espresso Ganache: Add a teaspoon of espresso powder to both the cake and ganache for bolder, mocha-like flavor.
- Orange Twist: Fold in the zest of one orange to the cake batter for a citrus-chocolate combination.
- Nutty Crunch: Sprinkle toasted chopped hazelnuts or almonds over the ganache as it sets for texture.
- Spice It Up: A pinch of cinnamon or cayenne in the batter gives a subtle warmth and depth.
Troubleshooting Common Issues
| Problem | Likely Cause | Solution |

| Dry Cake | Overbaking or insufficiently measured wet ingredients | Check cake early for doneness; measure with care |
