Preheat oven to 350 degrees.
Make crumb topping by mixing these ingredients:
1/2 cup all purpose flour
1/2 cup brown sugar
1 tsp. cinnamon
Then cut in 1/3 cup margarine or butter (pea sized bits).
Stir in 1/2 cup Old Fashioned Oats.
Stir all together. Take one cup to be mixed inside and save the rest for the topping.
Butter or spray Pam on the inside of 1 1/2 qt casserole dish.
Pour in 2 17 oz cans of Yams (drained),
2 cups fresh (washed and drained) or frozen cranberries
and the reserved 1 cup of crumb mixture.
Top with remaining crumb mixture and bake uncovered for 35 minutes in a 350 degree oven. Right before serving, sprinkle with 1 1/2 cups miniature marshmallows and broil until lightly browned (DO NOT WALK AWAY FROM THE BROILER, they burn quickly, even caught on fire once). It stays warm for quite a while, serve and enjoy.
I think my mother and I found this in a women’s magazine in the 70’s. It’s been a family favorite ever since.
