Preheat oven to 350
peel and chop sweet potatoes
boil until soft with jar of cinnamon sticks in the water
drain and take out cinnamon sticks
in a large bowl mix potatoes, and all remaining ingredients for potato mixture
(Mixture should be mashed slightly with a few chunks)
pour mixture into a 9x13 pan that has been sprayed with non stick cooking spray
Mix all ingredients for topping together and spoon onto the top of the potato mixture (I center the topping and leave about 2 inches around the entire pan)
cover and bake at 350 for 45 minutes, remove foil and bake for an additional 10 minutes.
Dish can be made ahead of time and baked when ready and also freezes well after cooked.
