For Lava Cake:

  • 4 teaspoons creamy peanut butter
  • 1 stick (113 grams) unsalted butter
  • cup (113 grams) chocolate I used semi-sweet
  • 2 large eggs
  • 2 egg yolks
  • ¼ cup (50 grams) granulated sugar
  • 1 tablespoon (8 grams) all-purpose flour


For Lava Cake:

  • Scoop heaping teaspoons of peanut butter onto a small plate. Place in freezer until ready to use.
  • Preheat oven to 350 degrees (F). Prepare 4 small ramekins by spraying them with non-stick spray. Pour a couple of spoonfuls of granulated sugar in the sprayed ramekin and roll around so that it coats the bottom and sides. This will create a sugar crust on the lava cake.
  • In a small saucepan combine the butter and chocolate. Place over low heat until melted. Remove from heat and allow to cool slightly.
  • In a medium bowl, whisk together the eggs, egg yolks, and sugar until slightly thickened. Add the cooled chocolate mixture and whisk until thickened. Add the flour and mix until combined.
  • Divide the batter evenly between the prepared ramekins. Place one ball of peanut butter in the center of each lava cake and press it down so it is covered by the chocolate batter.
  • Place the ramekins on a cookie sheet and bake for 15-17 minutes or until the outside is set and the very center is jiggly.
  • Remove from oven and carefully flip the ramekins over onto a plate or serve in the ramekins.


  • Watch the lava cakes closely while they bake. They can go from underbaked to over baked quickly and you will lose the gooey chocolate center.
  • Don’t use cold ingredients. Ensure that all of your cold ingredients are at room temperature before making your lava cakes. The ingredients will combine much easier.
