Introduction
These Chocolate Guinness Lava Cakes are a decadent treat combining rich chocolate with the unique depth of Guinness stout. Perfect for a special occasion or a cozy night in, they offer a molten center that delights every sweet tooth.

Ingredients
- 1 cup heavy cream
- 1/4 cup (28 g) confectioners’ sugar
- 1/4 cup sour cream
- 1 (11-oz) bottle Guinness stout
- 6 tablespoons unsalted butter, cut into cubes, plus more for tin
- 2 tablespoons plus 3/4 cup granulated sugar (150 g), divided
- 9 oz semisweet chocolate, coarsely chopped
- 3 large eggs
- 3 large egg yolks
- 3/4 teaspoon pure vanilla extract
- 6 tablespoons all-purpose flour
- 3 tablespoons unsweetened cocoa powder
- 3/4 teaspoon kosher salt
Instructions
- Step 1: Prepare the whipped cream by combining heavy cream, confectioners’ sugar, and sour cream in a chilled bowl. Whip until soft peaks form and refrigerate until ready to serve.
- Step 2: Preheat your oven to 425°F (220°C). Grease six 6-ounce ramekins with butter and dust with cocoa powder to prevent sticking.
- Step 3: In a small saucepan, combine the Guinness stout and 3/4 cup granulated sugar. Bring to a gentle boil and simmer until reduced by about half, then remove from heat and let cool slightly.
- Step 4: Place butter and chopped chocolate in a heatproof bowl. Pour the warm Guinness reduction over them and stir until smooth and fully combined.
- Step 5: In a separate bowl, whisk together eggs, egg yolks, 2 tablespoons granulated sugar, and vanilla extract until pale and slightly thickened.
- Step 6: Gradually whisk the chocolate mixture into the egg mixture until fully incorporated.
- Step 7: Sift together flour, cocoa powder, and kosher salt. Gently fold these dry ingredients into the wet mixture until just combined.
- Step 8: Divide the batter evenly among the prepared ramekins and place them on a baking sheet.
- Step 9: Bake for 12 to 14 minutes until the edges are set but the center still looks slightly soft.
- Step 10: Let the cakes cool for 1 to 2 minutes, then invert each ramekin onto a serving plate. Serve warm with whipped cream on top.
Tips & Variations
- Use good-quality semisweet chocolate for a richer flavor.
- Lightly dusting the ramekins with cocoa powder instead of flour helps maintain the rich chocolate crust without dryness.
- For a boozy twist, add a splash of Irish cream liqueur to the batter.
- Make the batter ahead and refrigerate; bring to room temperature before baking.
- Serve with fresh berries for a bright contrast.
Storage
These lava cakes are best enjoyed freshly baked. If needed, store leftovers covered in the refrigerator for up to 2 days. Reheat gently in a warm oven (about 300°F / 150°C) for 5 to 7 minutes — avoid microwaving as it may overcook the molten center.

FAQs
Can I use a different type of stout or beer?
Yes, you can substitute Guinness with another stout or a dark beer of your choice. Keep in mind the flavor may vary slightly depending on the beer’s bitterness and sweetness.
How do I know when the lava cakes are done?
The edges should be firm and set while the center remains soft and slightly jiggly. Overbaking will cause the molten center to cook through, losing the lava effect.

Ingredients
Whipped Cream
- 1 cup heavy cream
- 1/4 cup (28 g) confectioners’ sugar
- 1/4 cup sour cream
Lava Cakes
- 1 (11-oz) bottle Guinness stout
- 6 tbsp unsalted butter, cut into cubes, plus more for greasing tin
- 2 tbsp plus 3/4 cup (150 g) granulated sugar, divided
- 9 oz semisweet chocolate, coarsely chopped
- 3 large eggs
- 3 large egg yolks
- 3/4 tsp pure vanilla extract
- 6 tbsp all-purpose flour
- 3 tbsp unsweetened cocoa powder
- 3/4 tsp kosher salt
Instructions
- Prepare Whipped Cream: In a chilled mixing bowl, whip the heavy cream, confectioners’ sugar, and sour cream together using an electric mixer until soft peaks form. Refrigerate the whipped cream until ready to serve to allow flavors to meld and texture to firm.
- Reduce Guinness: Pour the entire bottle of Guinness stout into a small saucepan and bring to a simmer over medium heat. Reduce the stout until it measures about 1/4 cup, which concentrates its flavor. Let it cool slightly before use.
- Melt Butter and Chocolate: In a heatproof bowl set over a pot of simmering water (double boiler), melt the unsalted butter and semisweet chocolate together. Stir until smooth and fully combined. Remove from heat.
- Mix Sugar and Eggs: In a separate large bowl, whisk together the 2 tablespoons of granulated sugar, eggs, and egg yolks until pale and creamy.
- Combine Mixtures: Slowly pour the cooled, reduced Guinness into the egg mixture, whisking continuously. Then gradually fold in the melted chocolate and butter mixture until fully incorporated.
- Add Dry Ingredients: Sift together all-purpose flour, unsweetened cocoa powder, kosher salt, and remaining 3/4 cup granulated sugar. Gently fold these dry ingredients into the wet mixture, being careful not to overmix to keep the batter light.
- Prepare Molds: Butter individual ramekins thoroughly and lightly dust with cocoa powder or flour to prevent sticking.
- Bake Lava Cakes: Pour batter evenly into the prepared ramekins. Place them on a baking sheet and bake in a preheated oven at 425°F (220°C) for 12-14 minutes, or until the edges are set but the centers remain soft and gooey.
- Serve: Let the cakes cool slightly for 2-3 minutes, then invert onto serving plates. Top each cake with a generous dollop of the prepared whipped cream. Serve immediately to enjoy the warm molten centers.
Notes
- Ensure not to overbake the lava cakes; the center should be molten and gooey.
- Using a chilled bowl for whipping cream helps achieve better volume and texture.
- For easier unmolding, run a knife around the edges of ramekins before inverting.
- Leftover whipped cream can be stored in the refrigerator for up to 24 hours.
- Substitute sour cream with Greek yogurt for a lighter whipped cream variation.
