Frequently Asked Questions
What protein powder did you use?
I used the Be Well By Kelly vanilla protein powder, which mixes in perfectly and keeps these cookies soft and chewy.
Can I use almond butter instead of peanut butter?
Yes! Almond butter, cashew butter, or sunflower seed butter all work beautifully – just use the same amount.
How much protein is in each cookie?
Each cookie contains around 20 grams of protein, depending on your protein powder brand and mix-ins.
