How to Make Protein Bars

Whey isolate protein is great for recovery after exercise. Whey protein, packed with lean protein and broken chain amino acids, is commonly taken with shakes, but these are often unappetizing, messy and not very portable. Making your own protein bars allows you to create affordable, delicious and healthy post-workout recovery snacks, all in about 30 minutes.

  • Over-cooking your bars can lead to a very dry batch and it can be best to err on the side of under- rather than over-cooked.
  • Allow to cool completely before cutting into equal portions.
  • Allow the batch to cool for at least five minutes before gently working around the edge with a spatula in order to get underneath the cooked mixture.
  • Separate the bars carefully from the baking dish.
