If you don’t have a Bundt pan, the next best thing would be a 10-inch tube pan, like what you would use to make angel food cake (just be sure it’s well-greased if the pan is not coated!). You could also try using two 9-inch loaf pans, dividing the batter between the two pans. The bake time may be reduced by 10 or 15 minutes, so keep an eye on them during baking.
