I am about to make this cake for the third time this month. It is incredibly easy - all the ingredients go into one bowl at the same time - it doesn't have any tricky to find ingredients either. It keeps well in an airtight container for a few days and is DELICIOUS.
I serve mine with thickened orange yogurt. Another Martha idea from a brunch we had about twelve years ago. Line a sieve with a thick paper towel, one that is not likely to tear when it gets wet, or a clean tea towel. Place this over a bowl so it is not touching the bottom. Use this to strain the extra liquid from a plain unsweetened yogurt. After a couple of hours or even overnight it is thick and creamy. Flavor it with orange zest or a table spoon of freshly squeezed orange juice. Serve with cake as you would whipped cream.
