What’s in the Bowl
To create these indulgent Chocolate Peanut Butter Lava Cakes, you will need the following ingredients:
- 1 tablespoon unsweetened cocoa powder (5g) – for a rich chocolate flavor.
- 5 tablespoons all-purpose flour (38g, divided) – gives structure to the cakes.
- 9 tablespoons unsalted butter (127g, room temperature and divided) – creates a moist texture.
- 6 oz. German baking chocolate (170g, chopped) – ensures a deep, intense chocolate taste.
- 3 tablespoons creamy peanut butter (51g, low-fat or any nut butter) – adds that irresistible nutty flavor.
- 1 tablespoon powdered sugar (7g) – for a touch of sweetness.
- ½ cup granulated sugar (100g) – sweetens the batter.
- 3 large eggs (150g, room temperature) – helps bind the ingredients and creates a tender crumb.
- 1 pinch kosher salt – enhances the sweetness and balances the flavors.
Cook’s Kit
Before you start baking, make sure to gather the following kitchen tools:
- Ramekins – for baking and serving the lava cakes.
- Mixing bowls – for combining ingredients.
- Double boiler or microwave-safe bowl – for melting chocolate and butter.
- Whisk – to mix the ingredients smoothly.
- Spatula – for folding and scraping the batter.
- Oven mitts – for safely handling hot ramekins.
Build Chocolate Peanut Butter Lava Cakes Step by Step

Step 1: Preheat the Oven
Preheat your oven to 425°F (220°C). This high temperature ensures that the outer layer of the cakes sets quickly, while the inside remains gooey.
Step 2: Prepare the Ramekins
Grease four ramekins with 1 tablespoon of the softened butter and dust with cocoa powder. This step is crucial to ensure that the cakes release easily after baking.
Step 3: Melt Chocolate and Butter
In a double boiler or microwave-safe bowl, combine the chopped German baking chocolate and 4 tablespoons of the unsalted butter. Heat gently until melted and smooth, stirring occasionally. Set aside to cool slightly.
Step 4: Mix the Dry Ingredients
In a separate bowl, whisk together the flour, cocoa powder, and a pinch of salt. This ensures that the dry ingredients are evenly distributed throughout the batter.
Step 5: Combine the Sugars and Eggs
In another large mixing bowl, combine the granulated sugar and remaining softened butter. Beat with a whisk until creamy. Add the eggs, one at a time, mixing well after each addition. The mixture should be light and fluffy.
Step 6: Add the Melted Chocolate
Pour the melted chocolate mixture into the egg and sugar mixture, stirring gently until well combined.
Step 7: Incorporate the Dry Ingredients
Gradually add the flour and cocoa mixture to the chocolate batter. Use a spatula to fold the dry ingredients into the wet until just combined—be careful not to overmix!
Step 8: Add the Peanut Butter
Spoon the batter evenly into the prepared ramekins, filling each about halfway. Next, add a generous dollop of creamy peanut butter in the center of each ramekin, then cover with remaining batter until almost full.
Step 9: Bake
Place the ramekins on a baking sheet and bake in the preheated oven for 12-14 minutes, or until the edges are firm but the center still looks soft. They should not be overbaked; you want that lava effect!
Step 10: Cool and Serve
Remove the ramekins from the oven and let them cool for 1-2 minutes. Carefully run a knife around the edges to loosen the cakes. Invert each ramekin onto a plate, give it a gentle tap, and lift off the ramekin to reveal the molten center. Dust with powdered sugar before serving.
Health-Conscious Tweaks

If you’re looking to lighten up these Chocolate Peanut Butter Lava Cakes, consider the following options:
- Substitute low-fat butter with a plant-based butter for a dairy-free option.
- Use a sugar substitute like stevia or monk fruit to reduce the overall sugar content.
- Opt for dark chocolate with a higher cocoa percentage for less sugar and more antioxidants.
- Try natural nut butters without added sugars or oils for a healthier filling.
What I Learned Testing
During my testing of the Chocolate Peanut Butter Lava Cakes, I discovered a few important tips:
- The temperature of the eggs and butter plays a crucial role in achieving the right texture, so make sure they are at room temperature.
- Timing is key—underbaking slightly yields that perfect molten center, while overbaking turns them into regular cakes.
- Experimenting with different nut butters can create unique flavor profiles; almond or cashew butter also work beautifully!
- Dusting the ramekins with cocoa powder is essential for an elegant finish and helps with easy removal of the cakes.
Make-Ahead & Storage
If you’re planning for a special occasion or simply want to enjoy these delights later, you can prepare the batter in advance. Here’s how:
- Prepare the batter and fill the ramekins, then cover with plastic wrap and refrigerate for up to 24 hours before baking.
- When ready to bake, take them out of the fridge while preheating the oven, and bake as directed.
- These cakes are best enjoyed fresh, but you can store any leftovers in an airtight container for 1-2 days. Reheat in the microwave for about 15-20 seconds for a quick fix!
Reader Q&A
Can I use a different type of chocolate?
Absolutely! While German baking chocolate provides a rich flavor, you can substitute it with semi-sweet or bittersweet chocolate. Just adjust the sugar slightly if using sweeter chocolate.
How do I know when the lava cakes are done baking?
The edges should be firm while the center remains soft and slightly jiggly. A toothpick inserted into the edges should come out clean, but the middle should show wet batter.
Can I make these lava cakes gluten-free?
Yes, you can use a gluten-free flour blend instead of all-purpose flour. Be sure to check the blend contains xanthan gum for the best texture.
What can I serve with these lava cakes?
These Chocolate Peanut Butter Lava Cakes pair wonderfully with a scoop of vanilla ice cream, whipped cream, or a drizzle of chocolate sauce. Fresh berries also add a nice touch!
