Frequently Asked Questions
How much protein does each brownie have?
Each brownie contains 10 grams of protein, depending on your protein powder brand and portion size.
How do I store these protein brownies?
These 4-ingredient protein brownies can be stored in an airtight container. At room temperature, they’ll stay fresh for 1–2 days. In the refrigerator, they last up to 5 days, and for longer storage, you can freeze them for up to 2 months – just thaw or warm slightly before eating.
What kind of protein powder did you use?
I used Aloha plant-based chocolate protein powder, but any chocolate protein powder works! Whey, vegan, or collagen-based protein powders all work well in this recipe.
