Stuffed Brownie Choco Lava Cakes
Description
Stuffed Brownie Choco Lava Cakes combine a rich, fudgy brownie exterior with a warm, flowing chocolate center. The tops develop a delicate crackly crust, while a hidden chocolate ganache filling melts beautifully when you cut into each cake.
This recipe uses a separate chocolate filling, so you can bake the surrounding cake until set while keeping a molten center. Serve them warm with fresh raspberries, a light dusting of powdered sugar, or a scoop of vanilla ice cream for a beautiful homemade dessert.

Step-by-Step Instructions
1. Make the Chocolate Filling
Place the finely chopped chocolate in a small heatproof bowl. Heat the heavy cream in a small saucepan until steaming and just beginning to bubble around the edges.
Pour the cream over the chocolate. Leave it undisturbed for 2 minutes, then stir gently until smooth and glossy.
Refrigerate for approximately 45–60 minutes, until firm enough to scoop. Divide into six equal portions, approximately 1 tablespoon each. Place on a parchment-lined plate and keep refrigerated while you prepare the batter. If the filling is still too soft, chill it longer.
2. Prepare the Oven and Ramekins
Preheat the oven to 350°F (175°C).
Grease the bottoms and sides of six 6-ounce ramekins thoroughly with softened butter. Dust lightly with cocoa powder, tapping out the excess. Place the ramekins on a baking sheet for easier handling.
3. Melt the Butter and Chocolate
Combine the butter and chopped chocolate in a microwave-safe bowl. Microwave in 20-second intervals, stirring between each interval, until smooth.
Alternatively, melt them in a heatproof bowl set over gently simmering water, keeping the bowl above the water.
Let the mixture cool for about 5 minutes so it is warm rather than hot.
4. Mix the Wet Ingredients
In a separate bowl, whisk together the granulated sugar, brown sugar, and eggs for approximately 1 minute, until well combined and slightly thickened.
Whisk in the vanilla. Gradually stir in the warm chocolate-butter mixture until the batter looks smooth.
5. Fold in the Dry Ingredients
Sift the flour, cocoa powder, and salt over the wet mixture.
Fold gently with a spatula until no dry streaks remain. Avoid excessive mixing, which can make the cakes tougher. The finished batter should be thick and glossy.
6. Add the Hidden Filling
Divide approximately half the brownie batter among the prepared ramekins.
Place one chilled ganache portion in the center of each. Keep it away from the sides and gently press it slightly into the batter without pushing it to the bottom.
Cover with the remaining batter, ensuring the filling is completely enclosed. Smooth the tops gently. Leave some space below the rims for the cakes to rise.
7. Bake Until Set
Bake for 18–22 minutes, beginning your checks at 18 minutes.
The edges and tops should be set, with a delicate crust and no visibly liquid batter. A toothpick inserted into the cake near the edge, away from the ganache center, should come out with moist crumbs rather than wet batter.
The center may remain slightly soft because of the melted filling. Baking time can vary with ramekin shape and material.
8. Rest and Serve
Allow the cakes to rest for 5 minutes. Run a thin knife carefully around the inside edge of each ramekin.
Using oven gloves, invert onto individual plates and gently lift off the ramekins. You can also serve the cakes directly in their ramekins.
Dust lightly with powdered sugar and garnish with chocolate curls and raspberries. Serve warm so the chocolate filling flows when cut.
Serving Suggestions
Pair these cakes with vanilla ice cream for a contrast of warm chocolate and cold cream. Fresh raspberries or strawberries add brightness and balance the richness.
For a simpler presentation, serve each cake with a little whipped cream and a few chocolate shavings. Add toppings just before serving to keep everything looking fresh.
Recipe Tips
- Use baking chocolate: A chopped chocolate bar usually melts more smoothly than chocolate chips.
- Chill the filling thoroughly: Firm ganache is easier to position and cover.
- Measure flour carefully: Spoon it into the measuring cup and level it, or use the gram measurement.
- Grease every surface: Thorough preparation helps the cakes release cleanly.
- Check the cake around the filling: Testing directly in the center will pick up melted ganache.
- Serve promptly: The filling thickens as the cakes cool.
- Keep ramekin sizes consistent: Different sizes will change the baking time.
Easy Variations
- Coffee chocolate: Stir ½ teaspoon instant espresso powder into the melted butter and chocolate.
- Orange chocolate: Add 1 teaspoon finely grated orange zest to the batter.
- Nutty brownies: Fold 2 tablespoons finely chopped toasted walnuts into the batter.
- Darker chocolate: Use 60–70% dark chocolate for a less sweet, more intense result.
Make-Ahead Instructions
Prepare the ganache portions up to 2 days ahead and refrigerate in a covered container.
You can assemble the filled ramekins, cover them, and refrigerate for up to 24 hours before baking. Bake directly from the refrigerator, allowing a few extra minutes and checking the outer cake for doneness.
Storage and Reheating
Let leftover cakes cool, then refrigerate in an airtight container for up to 3 days.
Reheat individual cakes in the microwave in short 10–15-second intervals until warm. The filling will soften again, although the exterior may become softer than when freshly baked.
For longer storage, wrap cooled cakes individually and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
Frequently Asked Questions
Can I use a muffin tin?
Yes, but it will produce smaller cakes with a shorter baking time. Divide the batter and smaller filling portions among approximately 10–12 well-greased standard muffin cups. Begin checking around 12 minutes, and avoid overfilling.
Why isn’t the center flowing?
The cake may have cooled too much, or the ganache may be firmer because of the chocolate used. Warm it gently before serving.
Why did my cake break when unmolding?
It may need a little longer to rest, or the ramekin may not have been greased thoroughly. Make sure the outer cake is set before removing it from the oven.
Is the molten center raw batter?
In this recipe, the flowing center comes from the chocolate-and-cream filling. Bake the surrounding brownie batter until set.
