Pumpkin Spice Bread

The flavor is decent but the baking time was completely off. I've tried this recipe twice now. The first time, I made two regular size loaves and they came out underbaked and gummy. I had leftover pumpkin from a recipe earlier this week so decided to try again in case the first one was a fluke. I made four smaller loaves, started checking them at 30 min as instructed and finally took them out at around 45 min when the knife finally came out clean, then left them in the pan for the recommended 20 min... they still weren't done. With some tweaking, this could be good I think - maybe made as muffins instead of loaves? I'm not sure I'll be trying a third time though. There are too many recipes out there that work well the first time.
