Preheat oven to 350F, prepare 10-inch springform pan by greasing it and set aside.

In a medium size bowl add the cake mix and oil and mix until crumbly. Then press onto a bottom of the springform pan. Bake at 350F for 25 minutes. Remove from oven then increase the temperature to 450F.

In a large bowl, add the cream cheese and beat until smooth. Next add the sugar, vanilla extract, sour cream, and continue mixing. Slowly add the eggs and mix until well incorporated. Next in a small bowl, mix the chocolate chips with the all purpose flour, then add it into the cream cheese mixture.

Add the cream cheese mixture in the springform pan and bake at 450F for 7 minutes, then drop down the temperature 250F for 60-65 minutes.
