Preheat the oven to 350 degrees F. Heavily grease a standard size Bundt cake pan with cooking spray. Set aside.
In a large bowl, using an electric hand mixer, mix the cake mix, pudding mix, sour cream, eggs, water, and oil together until combined. Fold in the chopped white chocolate chips.
Pour only half of the cake batter into the prepared Bundt cake pan, spreading out evenly. Spoon half the raspberry pie filling in 6 spoonfuls evenly over the batter. Take a knife, and gently swirl into the batter. Be careful not to let the raspberry touch the sides of the cake pan. (it will burn if it does.)
Pour the remaining cake batter evenly over the raspberry filling swirls. Drop the remaining raspberry filling by spoonfuls all over the top. Using a clean knife, swirl the raspberry all over in the batter, being careful not to touch the sides of the cake pan with the raspberry.
Bake for 50 to 55 minutes or until cooked through. Carefully remove from the oven. Allow the cake to cool in the pan for 15 minutes, then invert and carefully release the cake onto a cake platter.
