Preheat oven to 400 degrees.

Spray 2 ramekins with non-stick spray and place in a baking pan.

Melt chocolate chips, peppermint bark, and butter in a bowl above hot, simmering water. Once melted, let cool slightly.

In another bowl, whisk together the egg, sugar and flour. Stir in cooled chocolate mixture.

Divide the batter into the ramekins.

Bake for 18-22 minutes. The tops should be slightly cracked and the chocolate underneath should remain somewhat gooey.

Remove from oven, cool just slightly, and serve.
