This easy pumpkin recipe has a thick, wet batter, so it takes a while to bake. If you take the loaf out too soon, the center may not be cooked all the way through. Check the doneness periodically by inserting a toothpick into the center of the bread. If it comes out with batter on the toothpick, put the bread back in the oven for a few more minutes before checking again. I also recommend using an oven thermometer to ensure your oven is at the correct temperature throughout.
