Yum...
1 cup pumpkin
1 cup sugar
1/2 cup brown sugar
1/2 c butter
1 egg
2 cups flour
2 t baking powder
2 t ground cinnamon
1/2 t salt
1 t baking soda
1 t milk
1 T vanilla
2 cups semisweet chocolate chips
1/2 cup chopped walnuts (optional) I added them, so good!
Combine soft butter and sugars. Beat till fluffy. Add in egg. Stir together dry ingredients. Add milk and vanilla to wet. Slowly stir in dry. Fold in cc and walnuts. Bake at 350 for 10-12 minutes. (I thought just over 11 was perfect in my oven)
