Xylitol - I made this keto recipe with xylitol. Feel free to use whatever sugar you’d like to here. If you’re aiming for sugar-free, you could try stevia, too. If you aren't sure free, maple syrup or coconut sugar would likely work. Add these sugars into the wet mixture while blending.
Eggs - if you have an egg allergy, I’ve been told that this format of recipe works really well with egg replacer but I have not tried it personally.
MCT Oil - you could use Alpha Energy; an MCT oil blend, or
Bulletproof Brain Octane. If you do not have access or are not interested in using MCT oil, coconut oil would work well, too.
