French vanilla whipped cream (regular will work fine too)
Add pineapple pieces, sugar, and cinnamon to a cocktail shaker and use a wooden spoon to muddle. Add lime juice, Private First Class, mint leaves, and give it a good shake. Pour into an ice filled glass, top with whipped cream, sprinkle with cinnamon, and garnish with mint sprig. Serve right away.
