This recipe is so good that I forgot to take a picture. I was too excited to eat it.

4 to 6 small sweet potatoes
1 1/2 T butter
1/8 t cinnamon
6 T milk
1/4 c - 1/2 c sugar
1 egg

Brown sugar crust:
1/2 c brown sugar
1 T flour
1/8 t cinnamon
1/4 c melted butter

Peel & boil potatoes. When tender, pour off water. Add butter, milk, sugar, egg & cinnamon. Whip with mixer until smooth. Pour into a 9 x9 pan and smooth out. Combine flour, brown sugar, cinnamon. First spread melted butter over mixture and then sprinkle the topping over butter. Bake at 375 for abt. 25 min. Top with pecans (opt).
