Eye-Catching Appeal: With its glossy ganache and dark color, this cake is sure to impress at any gathering.
Perfect for Any Occasion: From family dinners to festive celebrations, this cake fits the bill perfectly.
Diet-Friendly Options: While it’s a rich dessert, treat yourself in moderation or consider using gluten-free flour for an alternative version.

Ingredients You’ll Need

⅞ cup / 110 g all-purpose flour: This is the backbone of our cake, providing structure. If you need a gluten-free option, you can substitute it with a 1:1 gluten-free baking blend.
⅞ cups / 175 g granulated sugar: Adds sweetness, balancing the richness of the cocoa and stout.
½ cup / 45 g Dutch-process cocoa powder: This gives the cake a dark color and intense chocolate flavor. Be careful not to substitute with regular cocoa, as it may affect the acidity balance.
1 teaspoon baking powder: This helps the cake rise.
¼ teaspoon baking soda: Works with the acidic components to achieve that lovely rise and tender crumb.
¼ teaspoon fine sea salt: Enhances the overall flavor, a pinch makes a world of difference!
⅓ cup / 80 g full-fat sour cream: It’s key for moisture and richness, creating that irresistible texture.
¼ cup / 56 g vegetable oil: Adds moisture without weighing down the cake. You can switch this out with melted coconut oil for a hint of tropical flavor.
1 large egg: Acts as a binder for the ingredients. Use room-temperature eggs for optimal mixing.
2 teaspoons vanilla extract: Infuses warmth and depth to the flavor profile.
Scant ½ cup / 100 g hot brewed coffee or hot water: Enhances the chocolate flavor without making it taste like coffee.
⅓ cup / 80 g heavy cream: For the ganache, elevating the richness and giving that silky finish.
¼ cup / 56 g unsalted butter, cut into chunks: It provides decadence in the frosting. Always use unsalted to control the overall saltiness.
2 oz / 56 g good quality dark chocolate (60-70%), finely chopped: This is essential for ganache. Opt for high-quality chocolate for the best taste.
⅓ cup / 67 g granulated sugar: Another layer of sweetness for the frosting!
⅓ cup / 30 g Dutch-process cocoa powder, sifted: Intensifies the chocolate flavor in the frosting.
⅓ cup / 80 g full-fat sour cream: Gives the ganache a smooth, lush creaminess.
1 teaspoon vanilla extract: Reiterates those warm flavors in the frosting.
Pinch fine sea salt: It balances the sweetness and enhances all flavors.

How to Make Guinness Chocolate Cake | Rich Moist Chocolate Cake

Preheat oven: Start by setting your oven to 325°F (160°C). This helps the batter rise evenly. Prep an 8-inch round baking pan by buttering and lining it with parchment paper. This prevents sticking and allows for easy removal.

Whisk dry ingredients: In a large bowl, combine ⅞ cup of all-purpose flour, ⅞ cups of granulated sugar, ½ cup of sifted Dutch-process cocoa powder, 1 teaspoon of baking powder, ¼ teaspoon of baking soda, and ¼ teaspoon of fine sea salt. Give it a good whisk to ensure everything’s blended.

Mix wet ingredients: In another bowl or a 2-cup glass measuring cup, whisk together ⅓ cup of full-fat sour cream, ¼ cup of vegetable oil, 1 large room-temperature egg, and 2 teaspoons of vanilla extract until well blended. It should feel smooth and silky.

Combine mixtures: Make a well in the center of the dry ingredients and pour in your sour cream mixture. Gently stir the mixture until it’s almost integrated, leaving a few streaks of dry ingredients—this keeps your cake airy.

Incorporate liquid: Now, pour in the scant ½ cup of hot brewed coffee or hot water, and whisk until completely smooth. Don’t panic if it appears runny at first. The batter will come together beautifully.

Bake the cake: Pour the rich chocolate batter into your prepared pan, spreading it evenly. Bake for about 35 to 40 minutes, or until the center is springy. A toothpick inserted near the center should come out with a few moist crumbs attached—not gooey batter.

Cool the cake: Once done, remove it from the oven and allow it to cool in the pan for a few minutes. Then invert it onto a wire rack to cool completely. Skipping this step could lead to a soggy bottom.

Prepare the ganache: In a small saucepan, combine ⅓ cup of heavy cream and ¼ cup of unsalted butter, stirring gently over medium heat until melted. It doesn’t need to boil, just warm enough for the butter to melt.

Melt the chocolate: Remove from heat and add in 2 oz of chopped dark chocolate. Let it sit for a minute, then stir until completely melted and smooth. If necessary, return to low heat for about 30 seconds, stirring till smooth.

Add remaining ingredients to the ganache: Whisk in ⅓ cup of granulated sugar, ⅓ cup of sifted Dutch-process cocoa powder, and a pinch of fine sea salt. The mixture may look slightly grainy—don’t stress!

Finish the frosting: Mix in another ⅓ cup of full-fat sour cream and 1 teaspoon of vanilla extract, whisking until glossy and well blended. Cool down until it thickens slightly, about 15 to 30 minutes, so it’s spreadable.

Decorate the cake: Generously spread the decadent frosting onto the cooled cake, swirling with the back of a spoon or an offset spatula for an artistic touch.

Slice and serve: When ready to enjoy, slice the cake into generous pieces. You can serve it right away or refrigerate until serving. It holds at cool room temperature for a few hours, and leftovers can be stored in an airtight container in the refrigerator for up to five days.

Storing & Reheating

To store your Guinness Chocolate Cake, keep it at room temperature for several hours or refrigerate in an airtight container for up to five days. You can even freeze slices wrapped tightly in plastic wrap for up to three months. When reheating, gently warm in the microwave for about 10-15 seconds, just enough to soften without losing that irresistible texture and flavor.

Chef’s Helpful Tips

Remember to let your ingredients come to room temperature before mixing. This ensures a smooth batter and perfectly baked cake.
Don’t overmix the batter; gently fold in the wet ingredients to maintain that light sponge texture.
To avoid crumbs when frosting, refrigerate the cooled cake for about 30 minutes before adding your ganache.
If your cake rises unevenly, gently level the top with a serrated knife after it cools.
For a flavor twist, consider drizzling some espresso-infused syrup over the cake before frosting.

If you’re searching for a show-stopping dessert that is sure to impress both family and friends, Guinness Chocolate Cake is your answer. The rich flavors create a thick velvet-like cake that is perfect for any occasion. Don’t hesitate to explore variations, perhaps by adding your favorite nuts or substituting different types of chocolate.

Recipe FAQs

Can I bake this cake in advance?

Absolutely! The cake stores well, whether you’re refrigerating it or freezing individual slices. Just ensure it’s well-wrapped to keep it from drying out.

What can I use instead of Guinness?

You can substitute it with any dark stout beer, or for a non-alcoholic version, try using a combination of dark soda and brewed coffee for similar flavors.

Can I make this cake gluten-free?

Yes! Replacing the all-purpose flour with a gluten-free baking blend will yield good results. Be sure to check the individual ingredient labels for gluten-free assurance.

How do I prevent my cake from sinking in the middle?

Ensure your oven is at the right temperature before baking. A hot oven is crucial, and overmixing the batter can also lead to sinking, so mix only until combined.
