Question: are all bundt pans the same size?
Answer: Joanne, bake your recipe calling for a 9″ x 13″ pan (or two 9″ round pans) in either a 10-cup or 12-cup Bundt pan. Increase the baking time by about 30% in the 10-cup pan, somewhat less in the 12-cup. ... So while your Bundt pan size/capacity may be 10 cups, it's bakeable capacity is more like 6 cups.
