There’s no worry about this banana bread drying out at the edges, given the pot’s steamy environment. Here are the two secrets to success: First, make sure that pan is sprayed well, very nicely coated. If you think you’ve sprayed it enough, spray it a little more. The cake can stick like mad in the corners and indentions of the Bundt pan. And second, make sure the bananas as truly ripe, beyond the point you’d slice them onto cereal.
