Dairy-Free weight gainers?

Does anyone know if there are any dairy-free weight gainers out there? I know there are some great weight gainers that have around 1000 calories per serving, with a ton of protein... which is great and I have found it helped me gain a lot of weight in the past. But ever since finding out that I am allergic to Dairy, I've steadily been losing more and more weight as I have had my diet severely restricted.

So if anyone knows of a really good dairy-free weight gainer can you please tell me the name of it?

Thank you so much! I appreciate it :)
