DH and I are doing a 5th birthday party in a couple of weeks, and one of the invitees is vegan. I have said to her mum that I will happily cater for her, but actually, I don't know what I am doing . Vegan-friendly sandwiches, fruit and veggies are fine, but what about cakes/biscuit kind of things? The non-vegan children will be indulging, so I do want to have a vegan equivalent. I know I could ask the mum, but she sounded very grateful that I would do it, so am asking you lot instead . Any ideas?
