Directions

1. Preheat an oven to 350 degrees F (175 degrees C). Grease a 9 inch cake pan.
2. Melt 1 tablespoon of butter in a small skillet over medium heat. Stir in the apple, raisins, 1 tablespoon rum, and pinch of cinnamon. Cook until the apples are soft. Toss apples with bread cubes, and spoon into prepared pan.
3. Combine brown sugar, white sugar, 3/4 cup skim milk, evaporated milk, 1 tablespoon cinnamon, and 1/4 cup butter in a small saucepan over medium heat. Cook, stirring, until butter is melted. Allow to cool slightly and pour over bread cubes and apples.
4. Whisk the eggs and 1/2 teaspoon vanilla extract in a small bowl. Pour egg mixture evenly over bread and apples. Cover pan with aluminum foil; bake in preheated oven for 40 minutes. Remove foil and bake until pudding is puffed and lightly browned, about 10 additional minutes.
5. While the pudding bakes, prepare the rum sauce. Whisk together 3 tablespoons skim milk and the cornstarch in a small bowl. Melt the butter over medium heat in a small saucepan. Stir in 1 tablespoon rum and 1/4 cup white sugar; bring to a boil. Slowly add cornstarch mixture, stirring until sauce thickens. Remove from heat.
6. Pour rum sauce over warm pudding. Let rest for 5 minutes before serving. The sauce will continue to thicken and form a beautiful glaze.
