Place all the ingredients in the blender, except whipped cream, 2 tablespoons of apple-flavored syrup, and cinnamon, and blend until smooth and velvety.
Serve the Frappuccino in a tall glass and garnish with a generous amount of whipped cream.
Mix the remaining apple-flavored syrup with cinnamon thoroughly until perfectly combined, and drizzle the mixture on top of the whipped cream.
Place the Frappuccino in the fridge for about 10 minutes to chill and enjoy.
