Guinness Chocolate Cake Ingredients
For the Cake
• Nonstick Baking Spray – Ensures the cake slides out smoothly, preventing any sticking.
• Granulated Sugar – Sweetness and structure; can be reduced for a less sweet outcome.
• Light Brown Sugar – Adds moisture and a hint of caramel flavor; substitute with dark brown sugar for more depth.
• All-Purpose Flour – The cake’s foundation; gluten-free flour works for a gluten-free option.
• Unsweetened Cocoa Powder – Provides that deep chocolate richness; dark cocoa can intensify the flavor.
• Espresso Powder – A secret ingredient to enhance the chocolate taste; feel free to omit if you don’t have any.
• Baking Soda & Baking Powder – Essential leavening agents; ensure they are fresh for optimal rise.
• Salt – Balances out the sweetness; a key component in baking.
• Large Eggs – Vital for moisture and binding; use room temperature eggs for better incorporation.
• Full-Fat Sour Cream – Adds luxurious moisture; Greek yogurt can lighten it up.
• Guinness Beer – Imparts a unique depth of flavor; any stout can serve as a substitute.
• Vegetable Oil – Keeps the cake tender; melted butter can replace it for a richer flavor.
• Whole Milk – Enhances moisture; swap with non-dairy alternatives if desired.
• Vanilla Extract – Brings a lovely depth; high-quality extract will make a noticeable difference.
For the Baileys Buttercream
• Unsalted Butter – Creates a smooth, luscious frosting; use salted butter and adjust salt levels for flavor.
• Confectioners’ Sugar – Sweetens and thickens the buttercream; crucial for the perfect frosting consistency.
• Baileys Irish Cream – Adds that signature flavor to the frosting; non-alcoholic vanilla extract can be used instead.
• Whole Milk – Helps achieve a creamy consistency; cream can be used for an even richer texture.
• High-Quality White Chocolate – Imparts a luxurious creaminess to the frosting; semi-sweet chocolate can reduce sweetness.
For the Whiskey Salted Caramel
• Granulated Sugar & Water – Forms the base for your salted caramel; ensure the sugar dissolves completely.
• Unsalted Butter – Adds richness; cold butter helps prevent burning during cooking.
• Heavy Whipping Cream – Provides creaminess to the caramel; coconut cream works for a dairy-free option.

Step‑by‑Step Instructions for Decadent Chocolate Guinness Bundt Cake with Baileys Buttercream
Step 1: Preheat the Oven
Begin by preheating your oven to 325°F (163°C). This is an essential step to ensure even baking of your Guinness Chocolate Cake. While the oven heats, prepare your Bundt pan by thoroughly greasing it with nonstick baking spray to prevent any sticking later on.
Step 2: Mix Dry Ingredients
In a large mixing bowl, whisk together the granulated sugar, light brown sugar, all-purpose flour, unsweetened cocoa powder, espresso powder, baking soda, baking powder, and salt. Make sure no lumps remain, as these ingredients form the foundation of your cake. The chocolatey aroma filling your kitchen will be irresistible!
Step 3: Combine Wet Ingredients
In a separate bowl, combine the eggs, full-fat sour cream, Guinness beer, whole milk, vegetable oil, and vanilla extract. Whisk until the mixture is smooth and creamy. This wet mix will add moisture and richness to your cake, enhancing its decadent flavor profile.
Step 4: Combine Wet and Dry Mixtures
Gradually pour the wet ingredients into the bowl with the dry ingredients. Stir gently until just combined, ensuring not to over-mix. The batter should be rich and velvety, capturing the essence of the Guinness Chocolate Cake. You’ll know it’s ready when no flour streaks remain.
Step 5: Pour Batter into the Pan
Carefully pour the batter into your prepared Bundt pan, ensuring it spreads evenly. Gently tap the pan on the countertop to eliminate air bubbles, which can affect the cake’s texture. The batter will look dark and luscious, promising a moist and flavorful outcome.
Step 6: Bake the Cake
Place the Bundt pan in the preheated oven and bake for 50 minutes. To check for doneness, insert a toothpick into the center—if it comes out clean, your cake is ready. Keep an eye on it; the top should form a slight dome and look set.
Step 7: Cool the Cake
Once baked, remove the cake from the oven and let it cool in the pan for about 15 minutes. This cooling period allows the cake to firm up slightly, making it easier to invert. Then carefully turn the Bundt pan upside down over a wire rack to release the cake.
Step 8: Prepare the Baileys Buttercream
While the cake cools, prepare your Baileys buttercream. In a mixing bowl, beat the unsalted butter until smooth and creamy. Gradually add the confectioners’ sugar while continuing to mix, then pour in the Baileys, whole milk, vanilla extract, and a pinch of salt. Mix until fluffy and well-combined.
Step 9: Frost the Cake
Once the Guinness Chocolate Cake has cooled completely, use a spatula to frost the top and sides with the Baileys buttercream. The creamy frosting will add a delightful sweetness, perfectly balancing the rich chocolate flavor of the cake.
Step 10: Make Whiskey Salted Caramel
To enhance your decadent cake, prepare the whiskey salted caramel drizzle. In a saucepan, combine granulated sugar and water, cooking it over medium heat until the sugar dissolves. Once golden, carefully add butter and heavy whipping cream, followed by whiskey, and a pinch of sea salt. Drizzle this luxurious caramel over the frosted cake for an indulgent finish.

How to Store and Freeze Guinness Chocolate Cake
Room Temperature: Store the cake in an airtight container at room temperature for up to 3 days. This keeps it fresh while maintaining its moist texture.
Fridge: If you want to extend the shelf life, refrigerate the cake for up to a week, ensuring it’s covered well to prevent it from drying out.
Freezer: For longer storage, wrap slices or the whole cake tightly in plastic wrap and aluminum foil, then freeze for up to 3 months. Thaw in the fridge overnight before serving.
Reheating: To enjoy a slice warm, microwave it for about 10-15 seconds. The luscious flavors of this Guinness Chocolate Cake will be as inviting as when it was freshly baked!
Make Ahead Options
These Chocolate Guinness Bundt Cakes are perfect for busy home cooks looking to save time without sacrificing flavor! You can bake the cake up to 24 hours in advance; simply let it cool completely and store it tightly wrapped in plastic wrap at room temperature. The Baileys buttercream can also be prepared up to 3 days ahead—just keep it refrigerated in an airtight container. To maintain the buttercream’s creamy texture, give it a quick whip before spreading. When you’re ready to serve, frost the cake and drizzle with Irish whiskey salted caramel for a stunning finish that’s just as delicious as if you made it all in one day!
Expert Tips for Guinness Chocolate Cake
Room Temperature Ingredients: Ensure eggs and sour cream are at room temperature to guarantee even blending and a smoother batter, crucial for a perfect Guinness chocolate cake.
Don’t Overmix: When combining wet and dry ingredients, mix until just combined. Overmixing can lead to a dense texture rather than the desired lightness.
Check for Doneness: Use a toothpick to test if the cake is done. It should come out clean; too much moisture can make it heavy.
Cooling Time: Let the cake cool completely before frosting to prevent the Baileys buttercream from melting, ensuring a beautiful finish.
Caramel Attention: When making whiskey salted caramel, watch it closely as it cooks. Avoid stirring while it bubbles to prevent crystallization.
