  1. Filling: In a medium bowl, combine mascarpone cheese and sugar. Stir in chips. Set aside.
  2. Cupcakes: Heat oven to 350 degrees F. Line 24 medium muffin pans with paper liners.
  3. Follow directions on cake mix package. Fill each muffin liner 2/3 full.
  4. Drop heaping teaspoon of filling on top center of each cupcake.
  5. Bake according to cupcake directions on mix package, usually 23-25 minutes. (The batter will cover the mascarpone filling during baking.)

  7. Remove cupcakes to rack and cool completely.
  8. Frosting: Place chocolate in a medium microwave-safe bowl. Cook at high power 1 minute.
  9. Stir; continue cooking at high power 30 seconds. Stir until chocolate is completely melted.
  10. Immediately stir sour cream gradually into melted chocolate, mixing until smooth.
  11. Immediately spread over completely cooled cupcakes*; let stand until chocolate is set, about 15 minutes. Using white frosting with drawing tip, form squiggles across the cupcake frosting.
  12. Store covered at room temperature up to 2 days.

Yield: 24 cupcakes

* If icing becomes too stiff, microwave at high power 5 seconds to soften.
