Bake 28 to 32 minutes or until toothpick inserted in center comes out clean. Cool 10 minutes; run metal spatula around edge of pans to loosen cakes. Remove from pans to cooling rack. Cool completely, about 1 hour.

In large bowl, beat marshmallow creme, 1 cup softened butter, the vanilla and 1 tablespoon of the milk with electric mixer on medium speed until blended. Beat in powdered sugar until fluffy. If necessary, beat in more milk, a few drops at a time, until thin enough to spread. Stir in 1/4 cup shaved chocolate until just blended.

Place one cake layer on serving plate. Spread 3/4 cup frosting on top layer; top with second cake layer. Frost side and top of cake with remaining frosting. Sprinkle on top of cake, and press up side of cake the remaining 3 tablespoons shaved chocolate.
