Protein bars are awfully convenient. There's a catch: most of them are full of sugar and additives, comparable to a candy bar! I came up with a no bake protein bar recipe that uses five ingredients. You probably already have these in your kitchen, too. Use this recipe as a base for your no bake protein bar and add the extra ingredients of your choice if you want to play around with the flavour and texture. These protein bars are incredibly easy to make, completely customizable, and can be made vegan-friendly.
