Chocolate Kahlua Cake

I had this at my sis-in-law's house over New Years.  She made a mistake and used a brownie mix and it was more dense and fantastic. 

Mix together:

 1 chocolate cake mix (with pudding in the mix)
2/3 cup oil
3/4 cup Kahlua
3 eggs
1 cup sour cream

Stir in 1 cup chocolate chips. 

Pour into a greased and floured bundt pan.  Bake at 350 degrees for 45-50 minutes.  (If you are baking mini cakes, bake at 325 degrees for 20 minutes).  Cool for 10 minutes then turn onto a plate and dust with powdered sugar.
