How to Make Guinness Chocolate Cake | Rich Moist Chocolate Cake

Preheat: Start by preheating your oven to 325 degrees F. While that’s heating up, lightly butter or grease the bottom and sides of an 8-inch round baking pan. Don’t forget to line the bottom with a round of parchment paper to ensure easy removal later!

Whisk Dry Ingredients: In a mixing bowl, whisk together ⅞ cup all-purpose flour, ⅞ cup granulated sugar, ½ cup sifted dutch-process cocoa powder, 1 teaspoon baking powder, ¼ teaspoon baking soda, and ¼ teaspoon fine sea salt. This blend will provide the foundation for your rich chocolate cake.

Combine Wet Ingredients: In another bowl, or even better, a 2-cup glass measuring cup, whisk together ⅓ cup full-fat sour cream, ¼ cup vegetable oil, 1 large room temperature egg, and 2 teaspoons vanilla extract until everything is smoothly incorporated.

Mix Wet and Dry: Make a well in the center of your dry ingredients and pour in the sour cream mixture. Gently stir until it’s nearly combined, leaving a few streaks of dry ingredients.

Incorporate Coffee or Water: Now, pour in the scant ½ cup of hot brewed coffee or hot water. Don’t worry if it looks a bit sloppy; just keep stirring until the batter is smooth. A whisk can help incorporate any stubborn dry ingredients.

Bake: Pour your fudgy batter into the prepared pan, spreading it out evenly. Place it in the preheated oven and bake for 35-40 minutes. You’ll know it’s ready when the center springs back slightly, and a toothpick inserted comes out with a few moist crumbs (not gooey!).

Cool the Cake: Once baked, remove the cake from the oven and let it cool in the pan on a wire rack until it’s cool enough to handle. Carefully invert it onto the rack to cool completely.

Prepare Frosting: While the cake cools, combine ⅓ cup heavy cream and ¼ cup unsalted butter in a small saucepan over medium heat, stirring gently. Once the butter is melted, remove from heat and stir in 2 oz of finely chopped dark chocolate until completely melted.

Mix Frosting Ingredients: To your melted chocolate mixture, add ⅓ cup granulated sugar, ⅓ cup sifted cocoa powder, and a pinch of fine sea salt, whisking until all is well incorporated. It should resemble a slightly grainy brownie batter.

Add Last Ingredients: Whisk in ⅓ cup room temperature sour cream and 1 teaspoon vanilla extract until the mixture is smooth and shiny. Set this luscious frosting aside to cool, letting it thicken and become spreadable for about 15 to 30 minutes. Stir occasionally for even cooling.

Frost the Cake: Once the cake is completely cool, generously spread the frosting over the top, swirling it with the back of a spoon or an offset spatula for that beautifully rustic finish.

Serve: Slice it up, serve, and enjoy! Your delicious cake will hold at cool room temperature for a few hours, but if you’re not serving it right away, it’s best to refrigerate. Leftovers stored in an airtight container will keep fresh for up to 5 days.

Storing & Reheating

To store your delectable Guinness Chocolate Cake, keep it in an airtight container at room temperature for no more than a couple of hours if the room is cool. Otherwise, refrigerate it for up to 5 days to maintain freshness. If you’d like to freeze any leftovers, wrap slices tightly in plastic wrap and then in aluminum foil for up to three months. When you’re ready to enjoy them, let thaw in the fridge overnight, then warm gently in a 350 degrees F oven for about 10-15 minutes. Note that the texture might change slightly after freezing, but a quick warm-up will refresh it beautifully!

Chef’s Helpful Tips

Avoid Overmixing: It’s essential to mix just until the ingredients are combined to prevent a dense cake texture.
Check Oven Temperature: If your cake isn’t rising correctly, ensure your oven temperature is accurate with an oven thermometer.
Use Room Temperature Ingredients: For best results, let your eggs and sour cream be at room temperature, promoting even mixing and a better rise.
Choose Quality Chocolate: For the frosting, a higher quality dark chocolate makes a significant difference in flavor and texture.
Don’t Rush Cooling: Ensure the cake is completely cool before frosting for the best presentation and to avoid melting the frosting.
Experiment with Flavors: Feel free to add a tablespoon of espresso powder to the dry ingredients for even more depth, or swap out the Guinness for another stout or flavorful beer that you like!

Experience the delightful indulgence of this Guinness Chocolate Cake, the rich flavors and moist texture are bound to satisfy any chocolate lover. There’s something wonderfully comforting about making and sharing a homemade cake, so don’t hesitate to jump in and give this recipe a try. Enjoy every moment of creating and tasting this lovely dessert that holds a special place in the hearts of many!

Recipe FAQs

Can I use a different type of stout or beer?

Absolutely! While Guinness is a popular choice for this recipe, you can experiment with other stouts or even porters. Just keep in mind that each beer will impart its unique flavor, so choose one that you enjoy drinking.

Why did my cake not rise properly?

If your cake didn’t rise, it could be due to expired baking powder or baking soda. Always check the freshness of your leavening agents before beginning. Additionally, overmixing can lead to dense cakes, so mix only until the ingredients are combined.

Can I make this cake ahead of time?

Yes, you can bake the cake a day in advance. Just cool it completely, wrap it tightly in plastic wrap, and store it at room temperature. Frost it just before serving for the best presentation and taste.

What can I serve with this cake?

This cake pairs beautifully with whipped cream or a scoop of vanilla ice cream. You might also enjoy it with a light dusting of powdered sugar or cocoa powder for a simple yet elegant touch.

In a bowl, whisk together the all-purpose flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt.
In another bowl or a measuring cup, whisk the sour cream, vegetable oil, egg, and vanilla until well combined. Make a well in the center of the dry ingredients and pour in the wet mixture. Stir until nearly combined with a few dry streaks remaining.
