I adapted this recipe to make it a little healthier (reducing sugar and fat), and also adjusted some proportions so that it can be made with one (small) can of pumpkin (the size to make one pie).
Makes 24-30 muffins
1 1/2 c pumpkin (one small can)
1 1/2 c sugar
1 1/4 oil (I use olive oil, as the pumpkin flavor is strong enough to mask it)
2 3/4 c flour
2 tsp baking soda
2 tsp baking powder
1 tsp cinnamon
about 1 c chocolate chips (the original recipe called for 2 c, but that is really overkill if you want to consider this anything but a dessert!)
In a large bowl, beat eggs, sugar, pumpkin, and oil together until smooth. Add dry ingredients and mix well. Fold in chocolate chips. Fill greased muffin cups about 2/3 full. Bake at 400* for 16-20 min. Cool in pan 10 minutes before removing.
