A Frappuccino is actually a blended coffee drink made with coffee, milk, and ice, which gives it a thick and creamy texture. It's more like a coffee-based milkshake, if you will. So, while both drinks have coffee and milk in common, the way they're prepared and the final result are quite different.
Now, you might be thinking, "But what about the coffee flavor? Is it the same in both drinks?" Well, not exactly, since a latte has a more pronounced espresso flavor due to the shot of espresso used to make it. A Frappuccino, on the other hand, has a more subtle coffee flavor since the coffee is blended with other ingredients.
