Can I use a different flour besides coconut flour?

Coconut flour is much more absorbent than other flours. It allows us to use less to keep calories a little lower. But since it is more absorbent, you would have to 3-4x the amount if you wanted to replace with another flour. I used Bob’s Red Mill Coconut Flour .

How do I know when my Jumbo Red Velvet cookie is done?

For best results, insert a toothpick in the center of the cookie, when it comes out mostly clean, your cookie is done. The cookie will still cook some once it’s removed from the oven, so remove when you think it’s just about done. This will help create the gooey, cookie-like texture. If you want a more cake-like texture, wait until the toothpick comes out clean.

Can I use a different protein powder?

A whey + casein blend, like PEScience (recommended) or Quest, would work best for this recipe. Plant based protein powder also works really well. Whey-only protein powder blends (like Ghost, Clean Simple Eats, etc.), will make this cookie more dry and more likely to crumble.
