Just 5 ingredients in this Double Chocolate Protein Snack Cake, and one of them is your favorite chocolate whey!

I wanted to bring you an easy recipe made with whey protein, since many of you already have whey protein for shakes. It’s also a good opportunity for me to remind you that whey protein and vegan proteins bake up very differently. I often get messages from confused protein bakers who didn’t read the Notes section of the recipe where I mention the kind of substitutions that would work. They’ve replaced whey with vegan (or vice versa) and are wondering why their recipe didn’t turn out. Sometimes they just comment on the blog to tell me I wrote an awful recipe. :D

Whey protein just needs some wet ingredients to grow and fluff up when baked. (It needs the right amount of ingredients with the right texture, however, so that it doesn’t come out dry or rubbery.) Vegan proteins need egg whites (or a replacement) to fluff up when baked. Pea protein and egg whites make great protein pancakes, too! That’s the short story, anyway, so be sure to check the Notes section for adequate substitutions!


I made this cake with a great natural chocolate whey protein by Optimum Nutrition. It was the first one I started baking with years ago because it works well and has a reasonable price. Give this Double Chocolate Protein Snack Cake a try with your favorite chocolate whey!

A note about substitutions: other flours can be substituted for the coconut flour, but you'd need up to 2x more, since coconut flour is very drying. I would not recommend substituting other types of protein powder for the whey here.
