Pumpkin Muffin omission

I forgot to include one item that makes the pumpkin muffins taste just like the pumpkin bread at Great Harvest. I add a package of chocolate chips before I bake them. I like semi-sweet ones and Ralph likes milk chocolate. Both are good so it jusy depends on your own preference. I made a double batch andwe have been enjoying pumpkin bread and pumpkin muffins all week.
