This is one I discovered during my early cooking endeavors. Notice the first ingredient...that's right mashed potatoes! You must try this. It is very rich and you can't tell it is made with potatoes. Truly one of my favorite desserts.

2 cups mashed potatoes
3/4 cup butter
2 1/4 cups granulated sugar
3 eggs
1 3/4 cups all-purpose flour
2 teaspoons baking powder
1 teaspoon salt
1/2 cup milk
1 1/2 teaspoons cinnamon
1/2 teaspoon cream of tartar
1/2 teaspoon ground cloves
1/2 teaspoon nutmeg
2 ounces unsweetened chocolate, grated

Preheat oven to 350 degrees F. Grease AND flour baking pan.

Beat together butter and sugar. Beat in potatoes (make sure they are cool) and eggs, one at a time. Mix flour, baking powder, salt, cream of tartar and all the spices. Add flour mixture and milk to potato mixture, alternating and blending after each. Stir in chocolate. Bake for 50 minutes. Let cool and glaze (dissolve 3 tablespoons water in 1 cup powdered sugar).
