I made it super easy last week!

2 sweet potatoes, peeled, boiled, pureed in blender or food processor
1 T brown sugar
1 cup powdered sugar
2 *softenend packages cream cheese
2 eggs
Dash nutmeg, 2 dashes cinnamon

Mix above together with a mixer, briefly (don't over whip).

Pour that into a ready-made graham cracker crust.

Put in a water bath and bake in 350 oven for 1 hour. Open oven door and turn oven off. Leave cake in the oven. In another hour, take cake out and put in fridge for at least 3 hours or MORE! before serving.
