Vegan cake frosting

Me

Anyone knows delicious (preferably also vegan) cake frosting (not chocolate)? I’m baking a cake for my sons 1st birthday and wanted to find egg free frosting, dairy free would be even better. I have found two recipes.. one using coconut cream (milk), other one using coconut butter (which is sooo expensive and I have never tried it). Any other ideas? Or tried recipe?

Thank you all ☺️
