Brew coffee. Chill in the refrigerator for 15 minutes or overnight.
In a bowl whisk the heavy cream until stiff peaks form.
Put ice, cooled coffee, milk (or half & half), caramel sauce, sugar (to taste, if using), and vanilla into a blender. Mix on high until smooth.
Pour into glasses. Top with whipped cream and a drizzle of caramel sauce.
In a bowl mix together the cream cheese, garlic powder, and scallions until fully combined. Season with salt and pepper to taste. Then spread onto both halves of the bagel. Close the 2 halves together and cut in half.
Enjoy the bagel with Frappuccino.
