My low-cal caramel Starbucks frappuccino

So during summer I am addicted to the Starbucks caramel frappuccino except they can be over 400 calories. So I played around at home until I found the perfect recipe using low cal alternatives. And my at home recipe makes it cheaper too :) since u can make 10 drinks for the price of 1

Here Is my recipe:

Caramel frappuccino (under 90 calories)

1/2 a pack of Starbucks via iced Caramel
Add 2 packets of Truvia/Stevia powder
Dissolve the powder in 6oz water
Pour into blender
Add 1 1/2 cups of ice
And add about 1/2 cup almond milk( add just to ice line & add more if it's to thick)
