Am making cakes for our school summer fair tomorrow. My DDs are all gluten free so all the cakes I make are too and the recipes I use often use ground almonds. We're a nut free school, so can't use them in the cakes I make for school...am making a new recipe and have just noticed (trying to do too many things at once!), that it calls for ground almonds.
Any ideas what I can use instead - will some extra flour do the job?
