In a small pot over medium high-heat, warm the milk to a simmer, then add the brown sugar, cinnamon, ginger, cloves and nutmeg. Whisk the milk to a froth and add the oats. Stirring constantly, cook until the oatmeal is a smoothie-like consistency, about 2 1/2 minutes.
Pour the hot mixture into 4 mugs. Stir a shot of espresso into each and top with 1 tablespoon granola. Sip or spoon while it is still hot!
