Marble cake.....or rather my favorite marble cake. Warm spongy marble cake with a glass of milk=.heaven...it brings back nostalgic childhood memories of amma's cakes. Since I favor volume cooking I am addicted to cups and spoons.....I hate to weigh flour, butter etc...its so time consuming and irritating....some how volume cooking works out fine for me...even for baking...touchwood. *I am not a professional baker, I bake things. I use what I have on hand most of the time which means salted butter instead of unsalted, and use substitutes for cake flour, brown sugar, buttermilk etc. So, if you are an experienced baker, take note and adjust accordingly. Since this cake calls for cake flour...do not panic and there is no need to buy cake flour when you can make it at home, to make 1 cup of cake flour: put 2 tbsp of corn flour into a cup and fill it with flour. and sieve......your homemade cake flour is ready. Buttermilk substitute: To make 1 cup, pour 1 tbsp of lemon juic
