How To Make a Homemade Mass Gainer Shake

Follow along as I make an easy homemade mass gainer shake. If you're taking protein, creatine, pre-workout and other supplements, it might not be in your budget for a mass gainer shake. The recipe below is about 1/3 the price of commercial powder-based mass gainers and provides you with a dense, nutrient rich, high calorie shake.




  • 1c quick Oats
  • 1c Milk
  • 2 scoops whey protein
  • 1/2 banana (optional)
  • 2tbsp natural peanut butter (optional)
  • 1Tbsp Olive Oil (optional)


Use a magic bullet or blender to crush the oats into a fine powder. Mix everything in a blender and add a handful of ice.
