Pumpkin Pie Oatmeal with Graham Cracker Crumble

In a medium saucepan over high heat, bring milk to a boil. Stir in oats and salt, reduce heat to low, and simmer until oats are tender and creamy, 5 minutes. Meanwhile, in a small bowl, mix together canned pumpkin, 1 tablespoon brown sugar, and pumpkin pie spice. Stir pumpkin mixture into the oatmeal and sprinkle with cinnamon. In a small bowl, mix together butter, crushed graham cracker, and remaining 1 tablespoon brown sugar. Serve oatmeal in a bowl topped with graham cracker topping.
