Chocolate Peanut Butter Lava Cakes Recipe

Yields: 4 servings
Prep Time: 15 minutes
Cook Time: 12-15 minutes


For Cakes:

  • 1/2 cup (1 stick) unsalted butter, cut into cubes
  • 6 ounces high-quality bittersweet or semi-sweet chocolate, coarsely chopped
  • 3 large eggs
  • 1/3 cup plus 1 tablespoon granulated sugar
  • 1/8 teaspoon salt
  • 1/4 cup all-purpose flour

For Peanut Butter Filling:

  • 1/4 cup creamy peanut butter
  • 1 tablespoon powdered sugar


  • Softened butter and cocoa powder for preparing ramekins
  • Vanilla ice cream for serving (optional)


Prep the ramekins:

  • Preheat the oven to 425°F (218°C).
  • Grease four (6-ounce) ramekins generously with softened butter.
  • Dust the ramekins with cocoa powder, shaking out any excess. Place them on a baking sheet.

Melt chocolate & butter:

  • Place the butter and chocolate in a heatproof bowl.
  • Microwave in 30-second intervals, stirring in between, until melted and smooth. Set aside to cool slightly.

Make the batter:

  • Whisk together the eggs and sugar in a medium bowl until pale and slightly thickened.
  • Slowly whisk the cooled chocolate mixture into the egg mixture until fully combined.
  • Gently fold in the flour and salt until just incorporated.

Make peanut butter filling:

  • In a small bowl, whisk together peanut butter and powdered sugar until smooth.

Assemble lava cakes:

  • Divide half the batter among the prepared ramekins.
  • Drop a generous dollop (about a heaping teaspoon) of the peanut butter filling into the center of each ramekin.
  • Top the peanut butter filling with the remaining batter, dividing it evenly.


  • Bake for 12-15 minutes. The edges should be set, but the center should still appear slightly soft and jiggly. Do not overbake.

Invert and serve:

  • Let the cakes cool for 1-2 minutes.
  • Carefully run a thin knife around the edges of each cake to loosen them.
  • Place a serving plate over each ramekin and invert. The cake should release with the delicious molten center on top.
  • Serve immediately with a scoop of vanilla ice cream, if desired.


  • High-quality chocolate: Use the best chocolate you can find for a richer flavor.
  • Don’t overbake: The key to molten lava cakes is slightly underbaking them so the center remains gooey. Check them early!
  • Variations: Experiment with other nut butters or add-ins like chopped nuts, peanut butter chips, or chocolate chips to the filling.
  • Serving: Dust the cakes lightly with powdered sugar and serve while still warm for the best experience.

Enjoy this decadent chocolate peanut butter treat!
