Preheat oven to 350.
Spray a 14-inch round pizza pan with nonstick cooking spray.
Unroll crescent rolls and separate them into individual triangles. Arrange the triangles in an overlapping circle on the the pizza pan with the points out. Gently press the dough together where it overlaps.
Mix the cream cheese sugar and vanilla together on medium to high speed until well blended.
Spoon a generous tablespoon of the cream cheese mixture in the center of each triangle. Don't use it all!
Mix the chocolate hazelnut spread into the remaining cream cheese filling.
Drop an even amount of the chocolate filling on top of the vanilla filling.
Fold the points over the filling and tuck them into the center of the ring.
Bake at 350 for 20-25 minutes.
Mix the powdered sugar with the milk and drizzle the glaze over the crescent ring.
Let the glaze set for 15-20 minutes before serving.
