Pour coffee liquer evenly into 4 coffee glasses. Divide coffee and cinnamon evenly as well. Mix. Spoon whipped topping evenly over each coffee. Drizzle creme de menthe over the whipped topping. Place a mint pattie on top of each coffee. Serve immediately

Ps- this may sound strange, but I've put the mint pattie in with the hot coffee and just let the mint and chocolate melt into the drink. Nummy!!!
