hello! I have a lovely apple cake my sister loves but sometimes a full cake is too much for just the two of us. I usually third the recipe, but since the baking times are a bit weird, it never tastes as good as a whole cake The original recipe is 6oz butter, 9oz sugar, 12oz flour, 3 eggs, up to 1/4 cup of milk (incase mixture is too dry) and 4 apples. However, the baking time is 30 mins and 150 celcius and then 100 celsius till done (usually about 20 mins). How do I change the baking times to make the cake good? thankss!
