Good oil, eggs, sugar, flour, the zest of two oranges and a splash of whatever is open. It takes one bowl and a whisk and no equipment I do not already own.
It is not a celebration cake. It is the cake that sits under a cloth on the counter and gets smaller all week.
What goes wrong
Cheap oil. The cake tastes of the oil, so use the one you would pour on bread and accept the cost.
