"Proffee" could refer to a coffee drink that contains protein powder as an ingredient. This type of drink is often consumed as a meal replacement or as a way to increase protein intake while still enjoying the taste of coffee. The exact ingredients and recipe can vary, but it typically includes coffee, protein powder, and other ingredients such as sweeteners, creamer, and spices.
It is important to note that adding protein powder to coffee can affect the taste and texture, and it may not be suitable for everyone. It is recommended to choose a protein powder that is compatible with coffee and to carefully mix it in to prevent clumping.
