Baileys Guinness Cake Ingredients
- 1 cup Guinness stout – This rich stout adds depth and moisture to the cake, enhancing the chocolate flavor beautifully.
- 1 cup unsalted butter (softened) – Softened butter ensures easy creaming with sugar, creating a light and fluffy batter.
- 3/4 cup cocoa powder (unsweetened) – Unsweetened cocoa powder provides an intense chocolate taste that balances perfectly with the sweetness.
- 2 cups all-purpose flour – All-purpose flour gives structure to the cake, helping it rise while keeping it tender.
- 2 cups granulated sugar – Granulated sugar sweetens the cake and contributes to its moist texture by retaining moisture during baking.
- 1 tablespoon baking soda – Baking soda acts as a leavening agent, helping the cake rise and achieve a fluffy consistency.
- 1 teaspoon salt – A touch of salt enhances all the flavors and balances the sweetness in your Baileys Guinness Cake.
- 1 cup buttermilk – Buttermilk adds acidity, which tenderizes the gluten in flour, resulting in a moist and soft crumb.
- 2 large eggs – Eggs provide richness and act as a binding agent for the cake, ensuring it holds together beautifully.
- 1 tablespoon vanilla extract – Vanilla extract adds warmth and depth to the overall flavor profile of this decadent cake.
Frosting:
- 1 cup unsalted butter (softened) – Softened butter is essential for creating a creamy and spreadable frosting that adheres well to your cake layers.
- 4 cups powdered sugar – Powdered sugar gives structure and sweetness to the frosting, ensuring it holds its shape when piped or spread.
- 1/4 cup Baileys Irish Cream – This delightful addition infuses the frosting with a smooth Irish cream flavor that complements the chocolate perfectly.
- 1 teaspoon vanilla extract – A splash of vanilla enhances the overall taste of the frosting, making it even more irresistible.
- 2 tablespoons milk (if needed for consistency) – Use milk to adjust the frosting’s texture if it’s too thick for easy spreading or piping.
Directions: Baileys Guinness Cake
1. Preheat the oven to 350°F (175°C). Grease and flour a 9×13 inch cake pan, preparing it for the rich batter to come.
2. Combine the Guinness stout and softened butter in a large mixing bowl. Heat in the microwave until melted, stirring to blend the flavors beautifully.
3. Whisk in the unsweetened cocoa powder until smooth, creating a luscious chocolate mixture that will infuse your cake with deep flavor.
4. Mix together the all-purpose flour, granulated sugar, baking soda, and salt in another bowl. This step ensures all dry ingredients are well blended for even baking.
5. Whisk together the buttermilk, eggs, and vanilla extract in a separate bowl until combined. This mixture adds moisture and richness to your cake.
6. Combine the wet and dry ingredients by gently mixing them together until just combined. Be careful not to overmix; you want a tender crumb!
7. Pour the batter into the prepared cake pan and bake for 45 minutes or until a toothpick inserted comes out clean, indicating it’s perfectly baked.
8. Cool the cake completely in the pan before frosting it, allowing those delicious flavors to settle as it reaches room temperature.
For the Frosting:

Tips for the Best Baileys Guinness Cake
- Use Room Temperature Ingredients: Ensure your butter and eggs are at room temperature for a smoother batter that incorporates air better, leading to a lighter cake.
- Measure Flour Correctly: Spoon and level your flour instead of scooping. This prevents using too much flour, which can result in a dense Baileys Guinness Cake.
- Don’t Overmix Batter: Mix until ingredients are just combined. Overmixing can develop gluten, making the cake tough instead of moist and tender.
- Check Oven Temperature: Ovens can vary in actual temperature. Use an oven thermometer to ensure accurate baking, avoiding undercooked or burnt cake.
- Cool Completely Before Frosting: Allow the cake to cool completely in the pan to prevent the frosting from melting off, ensuring a beautifully frosted Baileys Guinness Cake.
- Adjust Frosting Consistency: If your frosting is too thick, add milk gradually until you reach your desired consistency, making it easy to spread without being runny.
How to Store and Freeze Baileys Guinness Cake

- Room Temperature: Keep the Baileys Guinness Cake covered at room temperature for up to 3 days to maintain its rich moisture and flavor.
- Fridge: Store any leftover cake in the fridge for up to a week, tightly wrapped or in an airtight container to prevent it from drying out.
- Freezer: For longer storage, freeze the cake (without frosting) for up to 3 months. Wrap it well in plastic wrap and foil before placing it in an airtight container.
- Reheating: Thaw frozen slices of Baileys Guinness Cake in the fridge overnight, then enjoy at room temperature or warm them slightly in the microwave for a cozy treat.

- Coffee Kick: Add 1 cup of brewed coffee instead of Guinness for an extra caffeine boost and deep flavor profile. The coffee enhances the chocolate notes, making every bite richer.
- Minty Fresh: Stir in 1 teaspoon of peppermint extract into the batter for a refreshing twist. This variation creates a delightful harmony between chocolate and mint that’s perfect for the holidays!
- Nutty Addition: Fold in 1 cup of chopped walnuts or pecans for a crunchy texture contrast. The nuts add a wonderful depth and make each slice even more delightful.
