A spoonful of coffee in the vanilla is lovely, give it a try when you get somemore...
Choc mint lovely hot
Half a pack of choc mint mixed with half a pack of strawberry...yummy
Half a pack of choc mixed with half a pack of banana, that's nice hot too.
My son has half a pack of toffee & walnut mixed with half a pack of choc, i don't like it but he does!
Hope this gives you some ideas....
Good luck with the mixing...xxx
