Preheat oven to 350. In a large bowl, combine the oats, brown sugar, cinnamon, baking powder, salt, and Craisins. In a smaller bowl, mis together the milk, butter, vanilla, and eggs. Add the liquid mixture to the dry mixture and whisk to combine. Pour into a deep 9" pie plate or an 8x8" or 9x9" baking dish. Bake for 40 minutes or until the top is golden brown. Serve immediately with a splash of warmed milk.
