Ingredients You’ll Need

Non-stick cooking spray or vegetable shortening: This helps to prepare the pan, ensuring your cake can be easily released after baking. If you’re concerned about sticking, consider lining the bottom with parchment paper.
2 cups all-purpose flour: Essential for structure, providing the cake with a lovely crumb. You can substitute with a gluten-free blend if needed.
2 ½ teaspoons baking soda: This gives the cake a nice lift, helping it rise beautifully during baking.
2 teaspoons instant espresso powder: Enhances the chocolate flavor; plus, you can substitute with strong brewed coffee if preferred.
2/3 cup full-fat sour cream: Adds moisture and richness to the cake; Greek yogurt can work as a substitute for a healthier option.
2 large eggs, room temperature: Essential for binding the ingredients together and adding richness. Bring them to room temperature for the best results.
1 tablespoon vanilla extract: Adds a lovely depth of flavor that complements the chocolate.
1 cup Guinness stout: This is the star ingredient, providing a unique flavor profile that pairs beautifully with chocolate.
1 cup (2 sticks) unsalted butter plus two tablespoons: Creates a moist cake. If you prefer a dairy-free option, you can use a good quality margarine.
2 cups caster/super fine sugar: Provides sweetness and helps with a smooth texture. You can make your own by processing granulated sugar in a food processor for a couple of minutes.
¾ cup Dutch-process cocoa powder: A key flavor contributor, it adds depth. Ensure you select high-quality cocoa for the best results.
8 ounces cream cheese: The base for the frosting, adding creaminess and tanginess that’s hard to resist.
1 ¼ cups confectioner’s sugar, plus more as needed: Provides sweetness and helps achieve a smooth frosting consistency.
1 teaspoon vanilla extract: Reinforces the flavors in the frosting, making it extra delightful.
½ cup heavy cream: Adds richness to the frosting, making it luscious and smooth.

How to Make Guinness Chocolate Cake

Preheat your oven to 350 degrees F. Prepare a 9-inch springform pan by spraying it with non-stick cooking spray or greasing it with vegetable shortening. For best results, line the bottom with a round piece of parchment paper.
In a large bowl, sift together 2 cups all-purpose flour, 2 ½ teaspoons baking soda, and 2 teaspoons instant espresso powder using a fine mesh strainer. Set aside these dry ingredients.
In a medium bowl, whisk together 2/3 cup full-fat sour cream, 2 large eggs (make sure they are at room temperature), and 1 tablespoon vanilla extract until well combined. Set aside to use later.
In a large saucepan, combine 1 cup Guinness stout and 1 cup (2 sticks) unsalted butter. Set over low heat, stirring occasionally until the butter is fully melted.
Once melted, add 2 cups caster sugar and ¾ cup Dutch-process cocoa powder to the saucepan. Stir together until well combined.
Remove the saucepan from heat. Take a few spoonfuls of the hot Guinness mixture and whisk it into the sour cream and egg mixture to temper it; this ensures the eggs don’t cook when added later.
Pour the tempered sour cream/egg mixture into the saucepan with the Guinness mixture. Whisk everything together until fully combined into a smooth batter.
Gradually whisk in the dry flour mixture, mixing until the batter is smooth and free from any pockets of flour. Be careful not to overmix, as this can toughen the cake.
Pour the cake batter into the prepared pan. If you’re using a cake strip, dampen it and wrap it around the pan; if your pan leaks, you can wrap some foil around the bottom loosely to catch any drips.
Bake for about 45 minutes, or until the center feels set. To test for doneness, insert a toothpick into the center; it should come out clean. Avoid overbaking to keep the cake moist.
Allow the cake to cool on a wire rack for at least 15 minutes before carefully loosening the springform clasp and removing the cake from the pan. Peel off the parchment liner and let it cool completely on the rack.
While the cake cools, prepare the frosting. In a mixing bowl, use a mixer to whip 8 ounces of cream cheese until it’s smooth and creamy. Gradually sift in ½ of the 1 ¼ cups confectioner’s sugar and mix again until smooth.
Add the remaining confectioner’s sugar along with 1 teaspoon vanilla extract and ½ cup heavy cream. Mix until the frosting is light, airy, and spreadable, adjusting with more confectioner’s sugar if needed for consistency.
Once the cake has cooled completely, place it on a cake serving plate. Spoon the frosting over the top, spreading it out with an offset spatula or the back of a large spoon to create peaks and swirls.

Storing & Reheating

To store your leftover Guinness Chocolate Cake, keep it covered at room temperature for up to two days. If you want to extend its shelf life, refrigerate it in an airtight container for up to a week. For longer storage, you can freeze the cake for up to three months. Wrap it tightly in plastic wrap and then in aluminum foil to protect it from freezer burn. When you’re ready to enjoy it again, simply thaw it in the refrigerator or at room temperature. The flavor and texture may change slightly, but you can refresh it by letting it sit at room temperature for a little while before serving.

Chef’s Helpful Tips

When separating eggs, be cautious to avoid shell fragments in your batter.
Ensure all your ingredients are at room temperature for the best mixing results.
Overmixing can lead to a denser cake, so mix until just combined.
To test the cake’s doneness, gently press the center; it should spring back if fully baked.
If your frosting feels too thick, thin it using a bit more heavy cream to reach your desired spreadability.
Consider making the cake a day in advance; it tastes even better after resting!

Guinness Chocolate Cake is sure to become one of your favorites! The combination of chocolate and stout creates a depth of flavor that’s absolutely irresistible, making every bite a delicious experience. I encourage you to experiment with different toppings or add extra ingredients like chocolate chips or nuts to make it your own. Enjoy this rich, decadent cake appealing to both chocolate lovers and those who appreciate a good stout. Happy baking!

Recipe FAQs

Can I make this cake ahead of time?

Absolutely! This cake can be made a day in advance and stored in an airtight container at room temperature or in the fridge if it’s frosted. The flavors deepen as it sits, making it even more delicious.

Can I use another type of beer?

Yes! While Guinness provides a unique flavor, you can experiment with other stouts or even porters for a similar effect. Just choose a beer that you enjoy drinking for the best results.

What can I use if I don’t have super fine sugar?

If you don’t have super fine sugar on hand, you can easily process regular granulated sugar in a food processor for a couple of minutes until it’s finely ground. This provides a similar texture for your cake.

How can I know if the cake is done?

For this recipe, a toothpick inserted into the center of the cake should come out clean or with a few moist crumbs attached. If you see wet batter, let it bake a bit longer, checking every few minutes.
