Alternatives to half and half and HWC in smoothies

I just started keto chow, and while I've had issues with dairy before I've never had a huge reaction to it other than grumbles. I generally use oat milk and plant butter for their cooking/drinking alternatives but I haven't found something that mimics the qualities of 1/2&1/2 and HWC in smoothies.

I generally make the smoothies with spinach ice cubes (pureed fresh and frozen in trays for convenience) a super greens additive powder, and vegan collagen. I just got the sample packs to try, but as they arent vegan I will probably switch to the base powder and use vegan protein powder I already have.

I'm not currently vegan but my consumption of animal products is very low, I'm using alternate protein sources and some meat replacements but I still do occasionally eat meat. I'm making the switch bc I'm finding it hard lately to eat solid food without getting nauseous, especially meat. Idk why, I'm in the medical field so it's not the raw appearance. It just feels gross in my mouth I guess lol.

Anyway, I figured I would ask here bc if I asked in the ketochow sub they'd just redirect me here anyway. If there is a better place for this post please lmk.

Any other liquid keto recipes you like or know of, sweet or savory also appreciated.

Thanks so much! 💜
