This recipe makes 4 individual cakes , half the recipe for just 2 cakes and double for eight!
If you don't have caster sugar, grind your regular granulated sugar slightly (one pulse).
Its best to check one ramekin first so you are sure not to over bake the insides, as baking times vary slightly due to oven , ramekin size and chilling times. But if you can't, do wait until the tops are domed and cracked ( above picture for reference!)
