Making a chocolate cake for dd's birthday tomorrow. Recipe is 175g butter, 150g flour, 50g cocoa powder, 150g sugar, 3eggs and 250ml souur cream. Recipe says to cook in one tin - 20.5cm/8in tin = for 40-50 min at 180 and then cut cake in 2 and sandwich together. Wouldn't it be better to put in 2 slightly smaller tins and not have to cut cake in 2? If so can I cook at same temp but I guess for a shorter time - say 20-30 mins? TIA
