In a bowl, cream the cheese until light. Gradually beat in 1 cup sugar. Beat in eggs, one at a time, mixing well after each addition. Blend in vanilla. Spoon or pour mixture in paper cups in cupcake pan, filling 3/4 full. Bake in preheated 350 degree oven for 30 minutes.

In small bowl stir together 8 ounces sour cream and 1/2 cup sugar. After cupcakes have baked 30 minutes, remove from oven and allow to settle down, approximately 1 to 2 minutes. Place 1 teaspoon of filling into center of each and return to oven for 5 minutes. Place 1 teaspoon cherry filling on each, after they've cooled. Refrigerate.
