Ingredients You’ll Need:

For the Cake:

• 1 cup Guinness (avoid the blonde ale – stick to dark stout)
• 1 cup (2 sticks) unsalted butter
• ¾ cup unsweetened cocoa powder
• 2 cups granulated sugar
• ¾ cup sour cream (room temperature)
• 2 large eggs
• 2 teaspoons vanilla extract
• 2 cups all-purpose flour
• 2 ½ teaspoons baking soda

For the Frosting:

• 8 oz cream cheese (softened)
• 1 ¼ cup powdered sugar
• ½ cup heavy cream

Instructions:

1. Preheat and Prep: Preheat the oven to 350°F (175°C). Grease and line a 9-inch springform pan with parchment paper for easy removal.
2. Melt the Butter and Guinness: In a large saucepan, combine the Guinness and butter over medium heat. Stir occasionally until the butter is fully melted. Remove from heat and whisk in the cocoa powder and sugar until smooth.
3. Mix the Wet Ingredients: In a separate bowl, whisk the sour cream, eggs, and vanilla extract until fully combined. Slowly pour this mixture into the saucepan with the Guinness and chocolate, whisking as you go.
4. Combine Dry Ingredients: In another bowl, whisk together the flour and baking soda. Gradually add the dry ingredients to the wet mixture, whisking until the batter is smooth and glossy.
5. Bake the Cake: Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 45-50 minutes or until a toothpick inserted into the center comes out with just a few moist crumbs. Allow the cake to cool in the pan for about 10 minutes before transferring to a wire rack.

Making the Cream Cheese Frosting:

1. Beat the softened cream cheese until smooth and fluffy.
2. Gradually add the powdered sugar, mixing until fully incorporated.
3. Slowly pour in the heavy cream, whipping until the frosting becomes light, creamy, and spreadable.

Assembling the Cake:

Once the cake is completely cool, generously spread the cream cheese frosting over the top. For a more rustic look, let the frosting drip naturally over the sides, or keep it clean by smoothing it out evenly across the top.

Tips for the Best Guinness Chocolate Cake

Room Temperature Ingredients: Make sure the sour cream and eggs are at room temperature for a smoother batter. Don’t Overbake: Keep an eye on the cake during the last 5 minutes to avoid drying it out. Chill Before Serving: Let the cake chill slightly in the fridge for 30 minutes before serving – it makes slicing easier and enhances the flavors.

Storage and Freshness Tips:

Room Temperature: If you’re planning to enjoy the cake within 1-2 days, store it in an airtight container at room temperature. Keep it in a cool spot away from direct sunlight. Refrigeration: For longer storage (up to 5 days), refrigerate the cake. Place it in an airtight container or cover it tightly with plastic wrap to prevent the cream cheese frosting from drying out. Before serving, let it sit at room temperature for 20-30 minutes to soften the frosting and enhance the flavors. Freezing: Want to make the cake ahead of time? The unfrosted cake can be wrapped tightly in plastic wrap and aluminum foil, then frozen for up to 3 months. Thaw it overnight in the fridge and frost it once fully thawed. Freezing Frosted Cake: If you need to freeze leftovers, slice the cake and place parchment paper between slices to prevent sticking. Store in a freezer-safe container for up to 1 month. Thaw slices individually at room temperature or in the fridge.

Bonus Tip: Freshness Boost: If the cake starts to feel a little dry after a few days, warm individual slices in the microwave for 10-15 seconds to bring back that fresh-from-the-oven feel.

Pairings & Serving Suggestions:

Serve with a glass of chilled Guinness or Irish coffee for the ultimate dessert experience. Top with chocolate shavings or a light dusting of cocoa powder for extra flair.
