I'm going to do a vanilla sponge with blue icing - probably buttercream which won't look smooth and lovely I know but will require less dexterity I feel (of which I have none, esp under pressure). I then plan to smother the messy icing with glittery sprinkles and flowers etc.
Please tell me (as if I were an idiot):
What tin/bowl do I get?
What method of lining/greasing said tin?
What quantities do I accordingly use for the cake?
I am not bad at baking but a rather basic amateur so take nothing for granted when explaining this to me ...
