I used my favourite cake recipe, the "No Fuss Fudge Cake" only because it's so quick and easy but you could use leftover cake of any kind, a packet cake mix, a sponge cake recipe or any other vanilla (or chocolate if you like) cake recipe.
Use your favourite vanilla cake recipe OR packet cake mix OR leftover cake cut into rounds, squares, whatever
1 pkt raspberry jelly (make up as per directions and refrigerate until nearly set)
desiccated coconut for rolling
fresh cream, whipped to a stiff consistency
