I am baking a birthday cake for a pupil in my class and have just remembered that I have run out of safe treats for my pupil with a gluten allergy. The only thing I can find at home is Ambrosia rice pudding. It only has a warning for dairy which he is able to eat. The ingredients are milk, whey, rice and sugar. This sounds safe to me but I wanted to check. Don't have time to go to shops before school sadly.
