1. Preheat oven to 350 degrees. In a large bowl, beat sugar, oil, pumpkin and eggs until well blended. Combine flour, baking soda, salt, baking powder and cinnamon in a small bowl. Gradually beat into pumpkin mixture until well blended.
2. Line cupcake pan with paper liners. Fill each line three quarters full. Bake 18-22 minutes or until a toothpick inserted in center comes out clean. Cool 10 minutes before removing to wire racks.

For Frosting:

1. Beat cream cheese and butter together for several minutes. Mix in confectioner’s sugar and vanilla. Beat until smooth and creamy.
2. Using an apple corer poke a hole in the center of each cupcake. If you don’t have an apple corer you can also cut a 1 inch by 1 inch circle in the center using a sharp knife. Set aside cake pieces.
3. Fill hole with frosting and add a little frosting on the top. Place reserved cake pieces on top and garnish with one clove.
