Ingredient List
- 1 tablespoon unsweetened cocoa powder (5g)
- 5 tablespoons all-purpose flour (38g, divided)
- 9 tablespoons unsalted butter, room temperature (127g, divided; 1 stick)
- 6 ounces German baking chocolate, chopped (170g)
- 3 tablespoons creamy peanut butter (51g, low-fat or any nut butter)
- 1 tablespoon powdered sugar (7g)
- ½ cup granulated sugar (100g)
- 3 large eggs, room temperature (150g)
- 1 pinch kosher salt
Before You Start: Equipment
- Ramekins: Four 6-ounce ramekins for baking the cakes.
- Double boiler or microwave-safe bowl: For melting the chocolate and butter.
- Mixing bowls: For combining ingredients.
- Whisk: For blending the batter smoothly.
- Baking sheet: To catch any overflow when baking.
- Spatula: For scraping down the sides of the mixing bowls.
Chocolate Peanut Butter Lava Cakes, Made Easy

Step 1: Preheat Your Oven
Preheat your oven to 425°F (220°C). This high temperature is essential for the cakes to bake quickly while keeping that delightful molten center.
Step 2: Prepare Your Ramekins
Grease the ramekins with 1 tablespoon of unsalted butter, then dust with cocoa powder, ensuring that the insides are evenly coated. This will help the cakes release easily after baking.
Step 3: Melt Chocolate and Butter
In a double boiler or a microwave-safe bowl, combine the chopped German baking chocolate and 8 tablespoons of unsalted butter. Melt them together, stirring until smooth. If using a microwave, heat in 30-second intervals to prevent burning.
Step 4: Mix the Dry Ingredients
In a separate bowl, whisk together the remaining 4 tablespoons of flour, unsweetened cocoa powder, and a pinch of kosher salt. Set aside.
Step 5: Combine Sugars and Eggs
In a mixing bowl, combine granulated sugar and eggs. Using a whisk, beat the mixture until it becomes pale and slightly thickened. This should take about 2-3 minutes.
Step 6: Combine Mixtures
Pour the melted chocolate mixture into the egg and sugar mixture, stirring until everything is well combined. Gradually fold in the dry ingredients until no streaks remain.
Step 7: Add Peanut Butter
Spoon 1 tablespoon of creamy peanut butter into the center of each ramekin. Then, pour the batter evenly over the peanut butter, filling each ramekin about ¾ full.
Step 8: Bake
Place the filled ramekins on a baking sheet and bake in the preheated oven for 12-14 minutes. The edges should be set, but the center will still look slightly soft and jiggly.
Step 9: Cool and Serve
Allow the cakes to cool for 1 minute before carefully inverting them onto individual plates. Dust with powdered sugar for a touch of elegance, and serve warm.
Seasonal Adaptations

- Fall: Incorporate pumpkin spice into the batter for a seasonal twist.
- Winter: Add a pinch of cinnamon or nutmeg for warmth.
- Spring: Serve with fresh berries for a refreshing contrast.
- Summer: Top with a scoop of vanilla ice cream for an extra indulgence.
Testing Timeline
When testing the Chocolate Peanut Butter Lava Cakes, keep an eye on the baking time. Here’s a quick timeline:
- 0 minutes: Preheat oven and prepare the batter.
- 12-14 minutes: Bake the cakes. Check for doneness at 12 minutes.
- 1 minute: Let the cakes cool slightly before serving.
Storage Pro Tips
To ensure your Chocolate Peanut Butter Lava Cakes remain fresh, follow these storage tips:
- Unbaked batter can be refrigerated for up to 2 days. Just cover the ramekins tightly with plastic wrap.
- Baked lava cakes are best enjoyed immediately, but they can be stored in the refrigerator for up to 2 days. Reheat in the microwave for 10-15 seconds before serving.
- For longer storage, freeze the unbaked ramekins. Just be sure to wrap them well in plastic wrap and foil. They can be baked straight from the freezer—just add a couple of extra minutes to the baking time.
Helpful Q&A
Can I use a different type of chocolate?
Absolutely! You can substitute semi-sweet or dark chocolate for the German baking chocolate. Just keep an eye on the sweetness levels, as different chocolates can alter the flavor profile.
What if I don’t have ramekins?
If you don’t have ramekins, you can use a muffin tin instead. Just adjust the baking time accordingly, and keep an eye on them as they bake.
How do I know when they are done baking?
The edges should be set, and the center should look soft and slightly jiggly. A toothpick inserted into the edges should come out clean, while one inserted in the center will be sticky.
Can I make these ahead of time?
Yes! You can prepare the batter in advance and store it in the refrigerator. Bake them fresh right before serving for the best molten center.
