Chocoate Chip Bundt Cake

1 yellow cake mix with pudding (will say that on the box) -
 I prefer Pillsbury moist supreme
1 sm. pkg chocolate instant pudding
1/2 C. sugar
3/4 C. vegetable oil
3/4 C. water
4 large eggs
1 C. sour cream
1 C. semi-sweet chocolate chips

Combine first 3 ingredients. Stir w/ fork or wire whip to remove large lumps. Add remaining ingredients except choc. chips. Stir until smooth. Stir in choc. chips. Pour into greased/floured (the Pam with flour works awesome) bundt pan. Bake @ 350 for 1 hr. (in my oven I only do 50 min. because it's a fast oven, and also because I like it super moist) Cool 10 min. on a wire rack in the pan. Remove from pan and cool completely. Sprinkle with powdered sugar and serve!
