Ingredients List
Gather these pantry staples and a bottle of Guinness for a guinness cake that tastes like indulgence wrapped in simplicity. Sensory note: Imagine the earthy fizz of stout mingling with cocoa’s bittersweet hug – pure bliss!
For the Cake:
- 1 cup Guinness stout (the star for that signature malty richness; sub non-alcoholic stout for a lighter twist)
- 1 cup unsalted butter, cubed (for buttery melt-in-your-mouth texture)
- 3/4 cup unsweetened cocoa powder (Dutch-processed for deeper chocolate notes; sub regular if needed)
- 2 cups all-purpose flour (sifted for fluffiness; whole wheat for a nuttier alternative)
- 2 cups granulated sugar (balances the stout’s bitterness)
- 1 1/2 teaspoons baking powder
- 1 1/2 teaspoons baking soda
- 1/2 teaspoon salt
- 2 large eggs (room temp for better emulsion)
- 2/3 cup sour cream (adds tang and moisture; Greek yogurt as dairy-free sub)
- 1 teaspoon vanilla extract
- 1/2 cup buttermilk (for extra tenderness; sub almond milk + lemon juice)
For the Cream Cheese Frosting:
- 8 oz cream cheese, softened (Philadelphia brand shines here)
- 1 1/2 cups powdered sugar (sifted to avoid lumps)
- 1/2 cup heavy cream (whips into airy peaks)
- 1 teaspoon vanilla extract
Yields one 9-inch cake (12 servings). Pro tip: Measure Guinness cold to preserve carbonation for fluffier rise!

Timing
This guinness cake is a time-saver dream:
- Prep Time: 15 minutes (quick mixing and assembly)
- Cook Time: 35 minutes (monitored baking for perfection)
- Total Time: 50 minutes (including cooling basics)
Compared to standard chocolate cakes averaging 60-70 minutes (per King Arthur Baking stats), this guinness cake recipe shaves off up to 20%, thanks to the stout’s acids activating leaveners faster. Ideal for weeknight treats or last-minute parties!
Step-by-Step Instructions
Step 1: Preheat and Prep Your Pan
Crank your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan (or line two 8-inch pans for layers). This prevents sticking – a game-changer for flawless release. Tip: Use baking spray for extra insurance.
Step 2: Melt the Magic – Guinness and Butter
In a saucepan over medium heat, warm 1 cup Guinness stout with 1 cup cubed butter. Stir until butter melts fully (about 5 minutes). The aroma? Heaven – frothy stout meets golden butter. Remove from heat.
Step 3: Infuse with Cocoa
Whisk in 3/4 cup unsweetened cocoa powder until silky smooth. Let cool 5 minutes. This guinness cake base sets the ultra-moist foundation; rushing here leads to lumps!
Step 4: Dry Ingredients Assembly
Sift 2 cups flour, 2 cups sugar, 1 1/2 tsp each baking powder/soda, and 1/2 tsp salt into a large bowl. Sifting = lighter crumb, backed by baking science for even aeration.
Step 5: Wet Mix Magic
In another bowl, whisk 2 eggs, 2/3 cup sour cream, and 1 tsp vanilla. Creamy and pale – your batter’s tangy soul.
Step 6: Combine Wet and Dry
Fold wet into dry gently until just combined. No overmixing – gluten hates that! Personalized trick: Use a spatula for that pro baker fold.
Step 7: Add Guinness Mixture and Buttermilk
Pour cooled chocolate stout mix into batter, stir smooth. Then blend in 1/2 cup buttermilk. Batter should be pourable like thick brownie mix – pour into pan(s).
Step 8: Bake to Perfection
Bake 30-35 minutes until toothpick-clean. Rotate midway for even browning. Your kitchen will smell like a pub bakery!
Step 9: Cool Like a Pro
Rest in pan 10 minutes, then wire rack to room temp (1 hour). Patience prevents soggy frosting.
Step 10: Frost and Finish
Beat cream cheese and powdered sugar smooth. Whip in heavy cream and vanilla for fluffy clouds. Spread generously. Slice and savor your guinness cake masterpiece!
