This is another recipe from my Cooking Light Cookbook, that has not failed me. I tried it a week ago and it was utter kitchen failure. However, it was not the recipe it was the baking pan that was too small and very dark. Which conduced the heat to the sides and made it rise faster than the center and it caused this weird concave issue in the middle. I bought a new loaf pan and my funds were quite well spent. I love Fat Daddio’s bakeware.
