Any recipe that doesn't have flour in will be gluten free. flapjacks, or even crispy cakes or cornflake crispy cakes, these dont have to be just for kids, they can be made on a tray and sliced up (mark the slices while they are warm if you want them to look neat ) you can add chopped cherries, raisins, coconut etc to make them a bit different.You could make a variety of different flavoured flapjacks, by making a basic mix, then splitting it up and adding various dried fruits, nuts ets. You could make all your refreshments that day gluten free by not using any flour, that way your guest will not be singled out,and you will not have to buy any ingredients that you won't use again. X
