Frequently Asked Questions

Can I skip the protein powder?

Yes, but the texture will be softer and less firm. Replace it with a few extra tablespoons of oats or almond flour for structure.

Are these cookies kid-friendly?

Absolutely! Kids love the banana and chocolate flavor. Just be mindful of the protein powder ingredients if serving to toddlers.

Can I make these nut-free?

Yes. Swap peanut or almond butter for sunflower seed butter or tahini. Always check for cross-contamination warnings if allergies are involved.

What type of protein powder works best?

Use a vanilla-flavored whey or plant-based protein powder. Unflavored protein may make the cookies less sweet unless you add extra honey.
