How to Make Guinness Chocolate Cake with Irish Cream Frosting
1. Preheat your oven to 350°F (175°C). This step is essential for achieving that perfect rise and a beautifully baked cake.
2. Grease two 9-inch round cake pans with butter and dust them lightly with flour. This prevents sticking and ensures easy removal once baked.
3. Mix the dry ingredients together in a bowl: flour, cocoa powder, baking soda, and salt. Whisk these together until well blended, creating a rich chocolate base.
4. Combine the wet ingredients in a separate bowl: Guinness, buttermilk, eggs, and vanilla extract. Mix until smooth; this will give the cake its moist texture.
5. Stir the wet mixture into the dry ingredients gently until just combined. Be careful not to overmix; you want a velvety batter without lumps.
6. Pour the batter evenly into your prepared cake pans. Tap them gently on the counter to remove any air bubbles—this helps your cakes bake evenly.
7. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Your kitchen will smell heavenly as they bake!
8. Cool the cakes in their pans for about 10 minutes before transferring them to wire racks. Allow them to cool completely so they’re ready for frosting.
For the Frosting:
9. Beat together softened butter and powdered sugar until fluffy and pale in color—about 3-4 minutes. This creates a light texture for your frosting.
10. Add Irish cream liqueur gradually while continuing to mix until fully incorporated and smooth. The flavor will elevate your frosting and pair beautifully with the cake.
11. Frost one layer of the cooled cake generously with Irish cream frosting, then stack the second layer on top and frost the top and sides for an indulgent finish.
Optional: Garnish with chocolate shavings or a drizzle of additional Irish cream liqueur for extra flair!

Expert Tips for Guinness Chocolate Cake with Irish Cream Frosting
- Use Fresh Ingredients: Always opt for fresh eggs, butter, and cream to enhance the cake’s rich flavors. Stale ingredients can dull the taste.
- Room Temperature: Ensure all refrigerated ingredients are at room temperature before mixing. This helps create a smoother batter that rises beautifully.
- Measure Precisely: Baking is a science! Use a kitchen scale for accuracy, especially with flour and sugar, to avoid a dense or dry cake.
- Avoid Overmixing: Mix just until combined when adding dry ingredients. Overmixing can lead to a tough texture in your Guinness chocolate cake.
- Cool Completely: Let the cake cool completely before frosting. If it’s warm, the Irish cream frosting may melt and slide off instead of setting beautifully.

- Room Temperature: Enjoy your Guinness Chocolate Cake with Irish Cream Frosting for up to 3 days stored in an airtight container, keeping it moist and flavorful.

Guinness Chocolate Cake with Irish Cream Frosting Recipe FAQs
What type of Guinness should I use for the cake?
For the best flavor, opt for a classic stout like Guinness Draught. Its rich, roasted malt notes enhance the chocolate, creating a beautifully deep flavor profile. The carbonation helps keep the cake moist, so avoid using any flavored varieties.
How should I store leftover cake?
Store any leftover Guinness Chocolate Cake in an airtight container at room temperature for up to 3 days. If your kitchen is particularly warm or humid, refrigerating it is a good idea to maintain freshness. Just remember to bring it back to room temperature before serving for optimal taste!
Can I freeze the cake or frosting?
Absolutely! You can freeze the unfrosted cake for up to 3 months. Wrap it tightly in plastic wrap and then in aluminum foil to prevent freezer burn. The frosting can also be frozen in an airtight container for about 2 months. Thaw both in the refrigerator overnight before enjoying them again.
Why did my cake sink in the middle?
A sinking cake often results from underbaking or incorporating too much air while mixing. Make sure your oven is properly preheated and use an oven thermometer if necessary. It’s also important not to overmix your batter; mix just until combined for the best rise!
Is there a gluten-free option for this recipe?
Yes! You can substitute all-purpose flour with a gluten-free blend that measures cup-for-cup, which will work beautifully here. Just ensure that your other ingredients, like baking powder and chocolate, are gluten-free as well.
Can I make this recipe dairy-free?
Certainly! For a dairy-free version, swap out the butter for a plant-based alternative and use dairy-free cream cheese or whipped coconut cream for frosting. Opt for dark chocolate without dairy and replace Irish cream with a non-dairy counterpart or homemade coconut cream mixture to keep those creamy flavors intact.
