Thirteen-year-old Joe Kozal was impressed by a molten chocolate cake in a restaurant but thought he could do better. Instead of chocolate, Joe's cakes ooze melted marshmallow.
1 1/3 cups semisweet chocolate chips
1/4 cup (1/8 lb.) butter
1/3 cup granulated sugar
2 large eggs
1/2 teaspoon vanilla
1 cup all-purpose flour
6 large marshmallows
Powdered sugar (optional)
How to Make It
In a 3- to 4-quart pan over very low heat, stir chocolate chips and butter until melted and smooth. Remove from heat and whisk in granulated sugar, eggs, and vanilla until well blended. Stir in flour.
Fill six buttered, floured ramekins (1/2-cup capacity; see notes) about halfway. Press a marshmallow into the center of the batter in each ramekin. Spoon remaining batter equally over marshmallows, completely covering.
Bake in the center of a 350° regular or 325° convection oven until tops are puffed up and crackly, 12 to 15 minutes. Let cool about 10 minutes, then run a knife along inside of ramekins and invert to release cakes. Place right side up on plates. Sprinkle tops with powdered sugar, if desired. Serve warm.
If you don't have ramekins, you can use muffin pans (about 1/2-cup capacity). Don't substitute chopped semisweet or bittersweet chocolate for the chocolate chips.
