There are a few notes to make if you are making it as a Bundt cake, and they are in the recipe card : - The cook time is approximately 35 minutes at 350 degrees F. - A Bundt cake generally is more dense than a sheet cake just because of the height and version of baking. You can adjust for that if you like. - A 9x13 sheet cake (as this recipe is) fits perfectly in a 10 cup Bundt pan. - Before putting in the oven, I sprinkle the walnuts and chocolate chips on the bottom. - For a Bundt cake, pat in the chips and walnuts to more easily allow them to fall as it bakes. - Reduce the white chocolate chips to 1/2 cup.
