Another highly popular and foolproof recipe from my childhood. We had it in loaf form and cupcake form, all expertly prepared by our black & white amah-che. Sometimes the cake was baked into shortcrust pastry cupcake shells. The cupcakes were stored in a Danish butter cookies tin that was kept on top of the fridge – well out of reach of hungry little hands!
Again, this one I had already typed up because so many friends & relatives had asked for the recipe before.
