In a medium saucepan, combine oats, milk, diced apple, brown sugar, ground cinnamon, and salt. Bring to a gentle boil over medium heat, stirring occasionally. Reduce heat and simmer for 5-7 minutes or until the oats are tender and the mixture thickens.
While the apple cinnamon oatmeal is cooking, brew your favorite coffee.
Pour the hot oatmeal into a bowl.
In a separate pot, mix brewed coffee, cocoa powder, and sugar. Heat gently while stirring until well combined and hot.
Pour the mocha into a cup.
Top each mocha with a generous dollop of whipped cream.
Garnish the whipped cream and a sprinkle of cocoa powder for an elegant touch.
Serve the mocha alongside the warm oatmeal.
