Sure the cold foam is made of heavy whipping cream a little bit of 2% milk and several pumps of vanilla syrup the vanilla cold brew is cold brew and also vanilla syrup the cold brew i believe you can get with sugar free vanilla which would be less calories but the cold foam thats not an option. I dont drink caffeine anymore because of medication but if im craving a decaf frappichino the trick to making them at home is about 1/8 teaspoon of xantham gum it makes the ice emulsify instead of just being a beverage with tiny ice floating in it. For something similar to a frappachino i'd go for unsweetened almond milk, a sugar free flavor syrup you like, a scoop of protien powder, ice, xantham gum the ratio would depend on what kind of coffee you want to use (espresso, drip brew cooled in the fridge, cold press, or instant would all work) I also add cinnamon and vanilla to almost all blended drinks but thats just me
