Preheat oven to 350 degrees.
In a large bowl, stir together cake mix, instant pudding mix, eggs, sour cream, and oil.
Fold in the chocolate chips, pecans, and coconut. You’ll notice that the batter is pretty thick, this is normal.
Spray a large (10 cup) bundt pan with non-stick spray.
Spread batter evenly into prepared pan.
Bake at 350 degrees for 40-45 minutes, or until a toothpick inserted near the center comes out clean.
Remove pan from oven to a wire rack to cool for 10 minutes, then carefully invert the cake onto the wire rack to cool completely.
