DIRECTIONS:

Preheat oven to 350 degrees F. Grease a 10-inch bundt pan.

In a medium bowl, stir together the cake mix and pudding mix. Add the sour cream, eggs, oil and grand marnier. Mix until smooth and well blended, then fold in the white chocolate chips. Pour the mixture into the prepared pan.

Bake for 1 hour in the preheated oven, until cake springs back to the touch. Allow cake to cool for 10 minutes in the pan, then turn out onto a wire rack to cool completely. When cake is cool, dust with powdered sugar and serve.
