Everything you need to know about making vegan whipped cream 

I haven’t tried it, but I think using erythritol instead of sugar should work. Both coconut and plant heavy cream usually are whipping up nicely even before adding sugar. Aqua faba could be a bit trickier, but I think cream tartar would help with that. Let me know if you try it!

No, not at the moment, but thanks for the offer tho.
