In a mixing cup, combine milk, sugar, vanilla bean paste, and caramel sauce together. Grab a stirrer and mix everything until well combined.
In a blender, carefully pour in the caramel milk mixture you made and then add the ice. Put the lid of the blender back on. Start from a low speed and then slowly progress to high speed.
Get a tall glass and rim it with caramel sauce. Slowly pour in your blended frappuccino and garnish it with your favorite toppings.
Sit back, relax, and enjoy your perfect Starbucks-style caramel frappuccino! Best served with a reusable straw.
