Brew the espresso shots using your preferred espresso making method (see this post for all the espresso making options). In a blender combine the sugar, espresso, whole milk, xanthan gum (if using), and ice cubes.
Blend the mixture until smooth and creamy.
To a 24-ounce glass, drizzle the caramel sauce and dark chocolate sauce all around the inside of the cup.
Pour the blended freeze into the prepared glass.
Top with whipped cream and more caramel and chocolate sauce drizzle and enjoy!
