Muffins may not be the healthiest snack of them all, but if you are going to have a muffin it might as well have the added benefit of protein and whole grains. Depending on the protein pancake mix you use, depends upon the ingredients and their ratios. Typically these protein pancake mixes will be made from whole wheat, almond, or oat flour. And they will have the addition of a protein blend which could include protein isolates, whey protein, or another form of protein powder.
