apple & almond cake~ it's astonishing how buttery this cake tastes, given that there is not a gram of butter in it. the flour is replaced with ground almonds - and cooked, cooled, pureed fruit provides moistness and flavour/nigella Recipe posted by Nigella
You just will not get the marzipan to ooze into the cake batter if it starts off fridge-cold. In dire straits, I have cubed it and given it a quick whirl in the microwave. And if you wanted to replace the vanilla extract with the zest of an orange, I wouldn't mind in the slightest.
