This cake transforms a bottle of stout into pure chocolate magic. The combination of deep, malty notes from the Guinness and rich cocoa creates an incredibly moist cake that's complemented perfectly by a coffee-kissed frosting. Each slice reveals layers of complex flavor that go far beyond ordinary chocolate cake.
I first made this cake for a friend's birthday, and the moment I added the Guinness to the melted butter, the kitchen filled with an aroma that had everyone gathering around the oven in anticipation.
Essential Ingredients and Selection Tips
- Guinness: Room temperature beer incorporates better; flat beer is actually preferred
- Cocoa Powder: Dutch-processed creates darker color and richer flavor
- Sour Cream: Full-fat provides moisture and tenderness
- Coffee: Fresh-brewed and cooled completely before using
- Butter: European-style for richer flavor in both cake and frosting

Detailed Instructions
- Preparing the Guinness Mixture:
- The Guinness-butter mixture needs careful attention. Watch for the moment when bubbles start forming at the edges - that's your signal to remove it from heat. When you add cocoa, whisk immediately to prevent lumps from forming.
- Combining Wet Ingredients:
- Temperature control is crucial when combining wet ingredients. The Guinness mixture should feel just warm to your touch before adding to the eggs and sour cream, preventing any curdling.
- Incorporating the Flour:
- When incorporating the flour, use a gentle folding motion rather than vigorous stirring. Watch for the moment when the last streaks of flour disappear - that's your stopping point. Overmixing develops gluten, making the cake tough.
- Making the Frosting:
- For the frosting, start with butter that's cool-room temperature - it should yield slightly when pressed but not be too soft. This ensures proper incorporation of powdered sugar and prevents a greasy texture.
- Assembly:
- When assembling, place strips of parchment under the cake edges to keep your serving plate clean. Remove them after frosting for a professional finish.

My grandmother always said that baking with beer was like adding a secret ingredient that transformed ordinary into extraordinary. This cake proves her right every time.
The Art of Layer Assembly
Stacking and frosting this cake requires special attention:
- Level each layer while still slightly warm for clean cuts
- Apply a crumb coat first and chill for 15 minutes
- Work from the center outward when spreading filling
- Keep edges slightly thicker than center for stability
Temperature Considerations
Understanding temperature's role is crucial:
- Room temperature ingredients blend more smoothly
- Chill layers briefly before frosting for cleaner assembly
- Let completed cake sit at room temperature for 1-2 hours before serving
- Store in a cool place but not in direct refrigeration
Frosting Techniques
Creating the perfect coffee frosting:
- Start with soft but not melted butter
- Add coffee gradually to prevent splitting
- Beat until light and fluffy - about 5-7 minutes
- Keep a small amount of warm frosting for touch-ups
Troubleshooting Common Issues
For sunken centers:
- Check oven temperature accuracy
- Avoid overmixing batter
- Don't open oven door during first 25 minutes
- Ensure baking soda is fresh
For dry cake:
- Don't overbake - remove when a few moist crumbs cling to tester
- Store properly covered
- Brush layers with coffee simple syrup if needed
Final Presentation Ideas
Create a pattern on top using cocoa powder and a stencil
Add chocolate curls or shavings
Drizzle with ganache
Pipe decorative borders with remaining frosting
