1 yellow cake mix
1 small vanilla instant pudding
3/4 cup vegetable oil
1 cup sour cream
Combine and beat well. Pour 1/3 into a well greased bundt pan (not floured).
Divide remaining batter in half. Into one half pour one small can Hershey's syrup (about 1 coup). Mix and add 6 oz chocolate chips. Pour chocolate mix over first layer, then pour last 1/3 into pan.
Bake 350º for 60 minutes. Let stand 15 minutes before turning out. Sprinkle powdered sugar over cake while still warm.
