Peel and cube sweet potatoes. Boil for 10 minutes , you should be able to pierce them with a fork .
Reserve 1 cup of the water and drain the sweet potatoes
Preheat oven to 350 degrees Melt butter in a 10inch skillet or 3 QT baking dish
Place drained sweet potatoes on top of the melted butter . Carefully spoon them over the butter in the skillet
Sprinkle the top of the sweet potatoes with the brown sugar and cinnamon
Mix the Self rising flour , milk , sugar and vanilla until smooth
Pour over the sweet potatoes evenly - DO NOT MIX
Pour the reserved hot water over evenly of the casserole -DO NOT MIX
Mix together 2 tablespoons of sugar and 1/4 teaspoon of sugar in a small bowl . Sprinkle it over the cobber - Again DO NOT MIX
Bake in the preheated oven for 40 minute or until bubbling and golden brown - If your dish is full I recommend putting an old baking sheet on the rack beneath this in case it bubbles over .
