Blueberry Muffins

I made this recipe twice with horrible results. The first time i made it i followed the instructions exactly and they were undercooked. The second time i changed the tempature to 450 and let them bake for 20 minutes. When i took them out I actually thought i had burnt them. But once i let them cool, i cut one in half and they were still undercooked. I don't know. maybe i am doing something wrong, but i was really dissapointed.

These muffins were so bland! I even used fresh blueberries. No one will eat at home.....had to throw away.

Easy to make. Turned out nice and light. Defiantely one to make again
