FAQs
Can I use a different type of protein powder?
Yes, you can substitute vanilla whey protein with plant-based protein powders like pea or rice protein. Just adjust the amount of milk as plant-based powders often require more liquid.
Are these bars suitable for people with nut allergies?
If you have a nut allergy, consider substituting peanut butter with sunflower seed butter and choose a nut-free protein powder to make the bars safe for your needs.
