Ingredients You’ll Need
The beauty of this Peanut Butter Chocolate Molten Lava Cake Recipe lies in its simplicity. A handful of essential ingredients come together to create that perfect texture, deep chocolate flavor, and irresistible molten center. Each component plays a vital role, from the smooth peanut butter that adds a luscious contrast to the bittersweet chocolate, to the eggs that provide a tender, yet rich cake base.
- 200g dark chocolate melts: The star of the show, dark chocolate brings an intense flavor and velvety texture.
- 100g unsalted butter, chopped: Adds richness and helps melt the chocolate smoothly.
- 2 whole eggs: Give structure and moisture to the cake.
- 2 egg yolks: Enrich the batter, creating an extra silky crumb.
- ½ cup caster sugar: Sweetens the batter just right without overpowering the chocolate.
- 2 tablespoons flour: Helps bind the ingredients while keeping the cake tender.
- 5 heaped teaspoons smooth peanut butter: The gooey molten centre that makes this cake unforgettable.
- Cocoa powder for dusting: Prevents sticking and adds a lovely hint of bitterness when dusted on the molds.
How to Make Peanut Butter Chocolate Molten Lava Cake Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 200°C (or 180°C for fan-forced ovens). This ensures the cakes bake evenly and develop their signature molten center. While the oven heats up, generously grease your 5 dariole moulds and dust them with cocoa powder. This little step makes sure your cakes slip out smoothly after baking.
Step 2: Melt the Chocolate and Butter
Combine the dark chocolate melts and chopped butter in a microwave-safe bowl. Heat them in 30-second bursts, stirring in between until smooth and fully melted. This mixture should be silky and luscious—let it cool for about five minutes before mixing it with the other ingredients.
Step 3: Whisk the Eggs and Sugar
In a separate bowl, whisk together the two whole eggs, the two egg yolks, and the caster sugar until the mixture is pale and slightly thickened. This step incorporates air into the batter, setting the stage for a light yet rich texture.
Step 4: Combine Chocolate with Eggs
Slowly pour the cooled chocolate and butter mixture into the egg mixture. Stir gently until everything is beautifully combined—the color should be a glossy, deep chocolate hue.
Step 5: Fold in the Flour
Add the flour and fold it through carefully, just until it disappears into the batter. Overmixing here can make the cakes dense, so be gentle to keep them tender and soft.
Step 6: Fill the Moulds with Batter and Peanut Butter
Pour the batter into each mould until it reaches halfway. Then, add a generous heaping teaspoon of smooth peanut butter into the center of each. Gently push it down so it submerges mostly but remains surrounded by batter. Top up the moulds with the remaining batter until they are three-quarters full—avoid overfilling to allow the cakes to rise beautifully without spilling over.
Step 7: Bake Until Perfect
Bake the cakes for about 16 minutes. You’ll know they’re ready when the tops spring back lightly when touched—the centers should still be soft, promising that molten core. Don’t overbake or you’ll lose that gorgeous molten texture we all adore.
Step 8: Remove and Serve
Once baked, turn the cakes out onto plates while still warm. Thanks to the cocoa dusting, they should slide right out. If not, run a knife around the edge carefully. Serve immediately to enjoy the full molten lava effect and the divine combination of peanut butter and chocolate.
How to Serve Peanut Butter Chocolate Molten Lava Cake Recipe

Garnishes
Enhance the beauty and flavor by adding light touches like a dusting of powdered sugar, a sprinkle of chopped roasted peanuts, or a few fresh berries. A small dollop of whipped cream or even a scoop of vanilla ice cream brings a cool contrast to the warm, molten cake. These simple garnishes elevate the presentation and the overall dessert experience.
Side Dishes
While this cake is a showstopper on its own, pairing it with a fresh fruit salad or a tart berry compote cuts through the richness and balances the flavors wonderfully. A cup of strong coffee or bold black tea also complements the intense chocolate and peanut butter flavors perfectly, making the experience complete.
Creative Ways to Present
For an extra special twist, serve the molten lava cakes in individual ramekins or elegant mini cake stands. Drizzle a little caramel or chocolate sauce on top or around the plate for a restaurant-worthy look. You can even experiment by adding a small scoop of peanut butter ice cream alongside to echo the molten center and amaze your guests.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers—which might be rare!—store them tightly covered in the fridge for up to two days. Keep in mind the molten center will firm up when chilled, so you might want to warm them up again before serving to bring back that ooey-gooey magic.
Freezing
You can freeze the unbaked batter portioned into moulds for up to a month. Wrap each mould tightly in plastic wrap and place in a freezer-safe container. When ready to bake, thaw overnight in the fridge and bake as usual—though baking times might be slightly longer.
Reheating
To reheat leftover cakes, gently warm them in a microwave in short bursts, about 15 seconds at a time, until just warm. Alternatively, use a low oven heat wrapped in foil to preserve moisture. The goal is to revive that molten ooze without drying out the cake.
FAQs
Can I use peanut butter other than smooth?
While smooth peanut butter is best for that gooey center, you can experiment with chunky peanut butter for added texture. Just make sure it’s not too dry or it might affect the flow of the molten lava inside.
What if I don’t have dariole moulds?
No worries! You can use ramekins or any small oven-safe cups around ¾ cup capacity. Just be sure to grease and dust with cocoa powder to help the cakes release easily after baking.
Can I substitute dark chocolate with milk chocolate?
You can substitute milk chocolate, but the cake will be sweeter and less intense in flavor. Opt for high-quality milk chocolate to keep the texture smooth and the taste rich.
Is there a way to make this recipe dairy-free?
Yes! Replace the butter with a dairy-free margarine or coconut oil and use dairy-free chocolate melts. The texture might vary slightly but the flavor will still be delightful.
Why did my cake not have a molten center?
The key is baking time. If your cake is baked too long, the center solidifies. Try reducing baking time by a minute or two and checking for a soft top that springs back gently. Also, make sure not to overfill the moulds, so the peanut butter remains surrounded by batter.
