It is often cheaper and healthier to make milkshakes to gain weight rather than purchase a pre-made shake mix. A tasty bulk-up shake can be made by using a protein, a carbohydrate, and a dietary fat. For this recipe, the protein is skim milk powder, oats are the carbohydrate, and peanut butter is the dietary fat. This recipe makes one serving, which contains approximately 685 calories.
Remove the lid from the blender and add one cup of skim milk. Whole, 1%, 2%, and soy milk can be substituted, if necessary or desired.
Add four tablespoons of skim milk powder to the blender. Add ¼ cup of raw oats, and replace the lid on the blender. Blend for fifteen to twenty seconds on medium speed.
Peel both bananas and slice them into small circular pieces. Remove the lid from the blender, and add them to the shake, along with three tablespoons of peanut butter.
Blend the mixture, starting on the lowest speed and gradually working up to the highest. Several seconds should be spent on each speed setting. Blend for at least 45 to 50 seconds in total.
Ensure the blender is turned off before removing the lid. Pour the shake directly into a large glass and enjoy immediately, or refrigerate to drink later.
