2 shots of espresso = 2 Nespresso espresso capsules
To make a 16 ounce (grande) Starbucks drink, you’ll need 2 Nespresso espresso capsules. You can also use 1 Vertuo double espresso capsule.
With the Vertuo machine capsules, only use espresso capsules and not the coffee capsules that make 7.77 ounces.
Starbucks makes all their lattes with 2% milk but you can use any kind of milk you like.
If you don't have a way to make espresso at home, use instant coffee. Combine 1 tablespoon of instant coffee and ¼ cup hot water to replace the 2 shots of espresso in the recipe.
I prefer using homemade vanilla syrup but you can buy Starbucks vanilla syrup directly from any of their store locations. The only catch is that it's not always available for purchase since they'll only sell it to you if they have extras in stock. At the store, it's about $14 for the bottle.
If you do use Starbucks vanilla syrup, use 2 tablespoons per drink since their syrups have a lot more sugar than my homemade version.
