Calories in Starbucks Double Chocolatey Chip Cream Frappuccino with lactose-free milk run from 280 in a Tall to 424 in a Venti, a little lighter than whole milk since the base swaps to a lower-fat carton.
A Grande lands at 379 calories with 18.8g of fat, compared to 21.4g with whole milk. Sugar stays almost unchanged at 41.0g, since the chocolate chips and mocha drizzle — not the milk — are doing the sweetening.
This matches the low-fat version exactly, and for a caffeinated take, Decaf Java Chip Frappuccino with lactose-free milk is close in richness.
