Can anyone help me with this? My daughter does'nt like birthday cake but loves Rocky Road bars. I am not an expert at cake making but this appeals to me as you dont have to cook it - just leave it to set in the fridge. Normally you make tis in a tray and cut into slices. Does anyone know if it will work in a round tin so I can make it look more like a birthday cake? I want to do something special for her but worried in case its a disaster!!
