I'm always worried about the raw flour tbh, it's not really safe to eat. Maybe use heat-treated flour or cook it on low heat just to be on the safe side? Also, softened butter... How soft we talking here? Microwave soft or just left out of the fridge?

A checklist...hmm, next thing ya know we'll need a checklist for making a checklist. But all jokes aside, ain't a bad idea. Especially for the forgetful folks out there 😂
