Recipe ingredients

The recipe list does look long but below are the key ingredients you actually need.

1) Protein Powder & Eggs

This recipe calls for PhD chocolate brownie protein powder which is perfect for protein recipes like chocolate brownies, protein mousse, and even protein chocolate ice cream! In fact, it comes with recipes and this recipe post is a slightly altered version that you can make at home. You can also drink it as a regular protein shake or test out other healthy recipes. This recipe also calls for eggs to help bind the ingredients. To substitute: You can use regular chocolate whey protein powder. However, it might not taste as good which is why this brownie flavored protein powder is better.

2) Bananas

As always, you cannot go wrong with mashed overripe bananas for these types of recipes which also helps prevent food wastage. Most protein recipes will look good on paper but taste horrible and bland. Using a sweetener helps and mashed bananas are a great alternative to regular granulated sugar. To substitute: This is the sweetener, but you can use fewer amounts of stevia or erythritol which can help reduce more calories in this recipe.

3) Nut Butter

Either peanut butter or almond butter is good for these protein bars as they add additional protein and healthy fats, as well as flavor.

Keep these stored in an air-tight container or freezer bag in the fridge for 7-10 days. It might keep well for longer but I would not know because they are usually all gone by then. I have kept these for more than a week, and they have been fine.
