Place all ingredients into the blender in the order listed and secure the lid. Blend on the lowest speed for five seconds and slowly increase speed to maximum.
Blend for one minute or until desired consistency is reached.
If you want the smoothie thinner, add additional milk.
Notes
If you prefer a sweeter smoothie, add honey, maple syrup, or your choice of sweetener to taste.
You can replace the yogurt with cottage cheese or ricotta cheese for an extra boost of protein.
The sweetness of the protein shake will vary depending on the protein powder you use.
If you don't want your protein powder to affect the sweetness of this strawberry protein shake, check the label and get unflavored and unsweetened protein powder.
If you purchase unflavored protein powder, it will still have a distinct taste. If you don't like the flavor of protein powder, you can use unflavored collagen powder. Collagen powder doesn't have all the amino acids that most protein powders have, but it is still a good source of protein and will not affect the flavor of the smoothie.
