- 2 cups granulated sugar – Sweetness balances the rich flavor of chocolate and stout while keeping the cake moist.
- 1.5 teaspoons baking soda – This leavening agent helps the cake rise, creating a light texture despite its richness.
- 1 teaspoon salt – Enhances all the flavors, making each bite deliciously balanced.
- 2 large eggs – Eggs provide moisture and help bind the ingredients together for a cohesive batter.
- 1 cup sour cream – Adds moisture and a slight tanginess that enriches the chocolate flavor in your cake.
- 2 teaspoons vanilla extract – Pure vanilla extract brings warmth and depth to this indulgent dessert.
- For the Frosting
- 8 ounces cream cheese (softened) – Cream cheese adds richness and a slight tang to offset the sweetness of the frosting.
- 1/2 cup unsalted butter (softened) – Softened butter ensures smooth blending with powdered sugar for a creamy texture.
- 4 cups powdered sugar – The main sweetener for frosting, creating a light and fluffy consistency that’s easy to spread.

Step-by-Step Guinness Chocolate Cake
1. Preheat the oven to 350°F (175°C). Grease and flour a 9×13 inch cake pan, ensuring a non-stick surface for your luscious cake.
2. Combine the Guinness stout and unsalted butter in a saucepan over medium heat. Stir until the butter melts completely, creating a rich base for your cake.
3. Whisk in the cocoa powder until the mixture is smooth. Set it aside to cool; this will deepen the chocolate flavor and enhance moisture.
4. Mix in a large bowl the all-purpose flour, granulated sugar, baking soda, and salt. This dry blend forms the essential structure of your cake.
5. Whisk together in another bowl the eggs, sour cream, and vanilla extract until well combined. This mixture adds richness and moisture to your cake.
6. Stir the cooled Guinness mixture into the egg mixture until fully combined. The deep flavors will meld beautifully as you mix.
7. Gradually add the wet ingredients to the dry ingredients, mixing gently until just combined. Over-mixing can lead to a denser texture—aim for fluffy!
8. Pour the batter into your prepared cake pan, spreading it evenly. Bake for 45 minutes or until a toothpick inserted comes out clean, filling your kitchen with heavenly scents.
9. Cool the cake completely before frosting; patience here allows for easier spreading and better flavor development.
10. Beat together cream cheese and softened butter in a mixing bowl until smooth and creamy—this will be your delightful frosting!
11. Gradually add powdered sugar while mixing until fully incorporated, creating a thick yet spreadable texture for your frosting.
12. Mix in the Guinness stout and vanilla extract until everything is smooth and creamy; this adds an extra layer of richness to your frosting.
13. Spread the frosting evenly over your cooled cake with love, making sure every slice gets that deliciously creamy topping.
Optional: Garnish with chocolate shavings for an extra touch of elegance!

Tips for the Best Guinness Chocolate Cake
- Cool Ingredients: Make sure the Guinness mixture cools slightly before adding to eggs; this prevents cooking the eggs and helps maintain a smooth batter.
- Sift Cocoa Powder: Sifting your cocoa powder helps eliminate lumps, ensuring a velvety texture in your Guinness Chocolate Cake that everyone will love.
- Don’t Overmix: Mix until just combined when incorporating wet and dry ingredients; overmixing can lead to a dense cake rather than the desired moistness.
- Proper Cooling: Allow the cake to cool completely before frosting; this prevents the frosting from melting and losing its creamy texture.
- Frosting Consistency: If your cream cheese frosting is too thick, add a splash more Guinness; this adjustment enhances flavor while achieving the perfect spreadable consistency.
How to Store and Freeze Guinness Chocolate Cake

- Room Temperature: Keep the cake covered at room temperature for up to 3 days. Use a cake dome or plastic wrap to maintain moisture.
- Fridge: Store leftover Guinness Chocolate Cake in an airtight container in the fridge for up to 1 week. This helps preserve its rich flavors and freshness.
- Freezer: For longer storage, freeze slices wrapped tightly in plastic wrap and aluminum foil for up to 3 months. Thaw in the fridge overnight before serving.
