Recipe Overview
- Yield: One stunning Bundt or 9-inch springform cake (10-12 generous slices)
- Prep time: 30 minutes (plus cooling)
- Bake time: 45-55 minutes
- Total time: About 2 hours (mostly hands-off cooling)
Ingredients – Cake
- 64 grams unsweetened Dutch-process cocoa powder (≈ ¾ cup lightly spooned, or ⅔ cup sifted)
- 624 grams Guinness Stout (reduced to 312 grams / ≈ 1¼ cups reduced; start with about 2½ cups / two standard cans)
- 100 grams eggs (≈ 2 large eggs)
- 400 grams granulated sugar (≈ 2 cups)
- 240 grams sour cream (≈ 1 cup full-fat)
- 165 grams sunflower oil (or neutral oil like canola; ≈ ¾ cup)
- 20 grams vanilla bean paste (≈ 1 generous tablespoon; or pure vanilla extract)
- 1 teaspoon instant espresso powder (≈ 3 grams; optional but amps up the chocolate—highly recommend!)
- ½ teaspoon ground cinnamon (≈ 1 gram; optional for warm spice)
- 210 grams all-purpose flour (≈ 1¾ cups spooned & leveled)
- 10 grams baking soda (≈ 2 teaspoons)
- 7 grams kosher salt (≈ 1 teaspoon + a pinch)
Ingredients – White Chocolate Cream Cheese Frosting (Baileys-Infused!)
- 170 grams white chocolate (≈ 6 oz good-quality bars or chips; melted and cooled slightly)
- 226 grams cream cheese, softened (≈ 8 oz / 1 block)
- 113 grams unsalted butter, softened (≈ ½ cup / 1 stick)
- 360-400 grams powdered sugar (≈ 3-3½ cups sifted; adjust to taste)
- 2-3 tablespoons Baileys Irish Cream (≈ 30-45 ml; start with 2 Tbsp—add more for creaminess! Jameson Irish Whiskey works beautifully as a bolder alternative)
- 1 teaspoon vanilla extract
- Pinch of salt
Optional Epic Fruit Add-Ons
- Fresh raspberries, strawberries, or blackberries (1-2 cups; scatter generously for tart contrast)
- Quick Raspberry Coulis: Simmer 2 cups fresh or frozen raspberries with ¼ cup sugar and 1 Tbsp lemon juice until juicy (5-7 min), strain for smooth sauce, cool, and drizzle over slices
Step-by-Step Instructions
- Reduce the Guinness (The Secret to Depth!)
Pour the 624 grams Guinness into a wide saucepan. Simmer gently over medium heat until reduced by half to 312 grams (≈ 1¼ cups)—about 20-30 minutes. Watch the foam and stir occasionally. Cool completely (fridge speeds it up). This concentrates those gorgeous roasted notes—your cake will thank you! - Prep the Pan
Preheat oven to 350°F (177°C). Generously spray a Bundt pan or 9-inch springform with baking spray. Dust with cocoa powder, rotate to coat, tap out excess. Gorgeous dark crust incoming! - Mix the Batter
In a large bowl, beat eggs and sugar with a handheld mixer on medium-high until pale and fluffy (2-3 minutes)—this builds tenderness! Add sour cream, oil, vanilla, cooled Guinness reduction, espresso powder, and cinnamon. Mix until silky.
Whisk or sift flour, baking soda, salt, and cocoa together. Fold in gently until just combined—no overmixing for that fudgy crumb! - Bake
Pour into prepared pan, tap to release bubbles. Bake 45-55 minutes until a skewer has moist crumbs or internal temp hits 206°F (97°C). Cool in pan 15 minutes, then release/invert and cool fully on a rack. Flavors bloom as it rests—patience pays off! - Make the Frosting
Melt white chocolate gently, cool slightly. Beat cream cheese and butter until fluffy (2 minutes). Add melted chocolate, then gradually powdered sugar, Baileys (or Jameson!), vanilla, and salt. Whip until light and spreadable—taste and adjust. Dreamy! - Assemble & Elevate
Frost the cooled cake with swirls and drama. Scatter fresh berries or drizzle raspberry coulis. Add chocolate shavings, a light cocoa dust, or extra Guinness syrup (reduce more stout with sugar) for extra wow. Slice and watch the magic happen!
Pro Tips from the Coordinated Cook’s Kitchen
- Test Batch Results? Baileys for creamy sweetness, Jameson for a sharper whiskey edge—both tie in that Irish soul perfectly. Pick your preference!
- Make ahead: Cake freezes beautifully unfrosted; frosting keeps 3-4 days chilled.
- Fruit boost: Raspberries cut the richness like nothing else—try them first!
- Pan variations: Baking time can shift depending on the pan! Our 45-55 minute range is spot-on for a standard Bundt or 9-inch springform. For loaf pans (e.g., one 9×5-inch or two smaller), expect 55-70+ minutes—start checking at 50 minutes (aim for 206°F internal). Tent with foil if browning too fast.
Frequently Asked Questions
Can I make this alcohol-free?
Absolutely! Swap the Guinness reduction for strong brewed coffee or non-alcoholic stout. Skip Baileys/Jameson in the frosting and use milk or vanilla instead.
Why reduce the Guinness?
It intensifies the malt and roast flavors without making the cake too wet or boozy—game-changer for depth!
Best pan?
Bundt for dramatic presentation and even baking; springform for easy slicing if you prefer layers.
Storage?
Keep frosted cake covered at room temp 1-2 days or refrigerated up to 5. Bring to room temp before serving for best texture.
Other fruit ideas?
Fresh strawberries for classic sweetness, blackberries for deeper tartness, or even cherries for a bolder contrast—all pair gorgeously with the chocolate-stout vibe.
