Heat oven to 350F. Mix the flour, baking soda, salt and cinnamon and set aside. In a large mixing bowl add the butter, egg, brown sugar, pudding mix and vanilla.
Add your dry mixture into your butter mixture and blend well. Fold in your milk chocolate chips. I use a small ice cream scoop to put dough on the sheet. Bake 5 minutes or until cookie is set. Watch carefully not to let these burn.
