Preheat oven to 350 degrees. In a large bowl, mix together pumpkin, nutmeg, cake mix, and butter. Add milk and mix until a thick batter is formed.
Spoon batter into lined cupcake tins and bake for eighteen minutes. This would be a good time to make the caramel sauce.
Cool cupcakes completely then poke four or five holes in each.
Drizzle with warm caramel glaze and serve.
