Upside-down plum cake

Upside down plum cake served with creme fraiche
This was a bit of an experimental recipe, which turned out to be absolutely gorgeous (forgive me if I blow my own trumpet on this one, but it really was a scrumptious cake: light, moist, rich, sweet and spicy). Obviously the idea comes from a pineapple upside-down cake, which has become to be regarded as somewhat of a retro cake that would fit in at a 70s themed dinner party along with prawn cocktail, cheese fondue and duck a l’orange. Now I don’t mind telling you: that sounds like a great menu to me, “retro” or not. With plums still in season they seemed like the obvious fruit choice, and they work well with festive spices like cinnamon and nutmeg. A simple vanilla sponge cake recipe made using the all-in-one method was all that was needed to top (or bottom, depending on which way round you look at it…) the fruit.

I do have a confession to make about the execution of this recipe, which will demonstrate how things in my kitchen don’t always go so smoothly (as if you needed that after mayonnaise-gate). The oven was at temperature, the cake was layered in the tin and I popped it into the oven with great anticipation. Less than five minutes later acrid black smoke was billowing from the oven as a little of the sugar and butter mixture (and presumably some juice from the plums) oozed out the bottom of the cake tin and hit the hot oven floor. At the speed of lightning I whipped the tin out, onto a baking tray and back into the oven, to prevent it getting worse. Luckily, neither the opening of the oven door at the start of baking or the smoke seemed to affect the quality of the cake in the end. SO, if anyone has any bright ideas about how to prevent this from happening do leave a comment below! For now, my advice would be to put the cake tin on a baking tray from the start or perhaps to use a cake tin that doesn’t have a loose bottom (though in this case I would grease the tin extremely well as it may be more difficult to turn out).

4. Spread the creamed butter and sugar onto the bottom of the cake tin and push the plums into the mixture, cut side down. Pack the plums tightly together – you may need to cut the final one into more than halves in order to fill all the gaps.

5. Place the ingredients for the sponge (butter, sugar, flour, baking powder, vanilla and eggs) into a large bowl. Using an electric whisk beat together the ingredients until everything is incorporated and you have an incredibly light, fluffy mix.

6. Spoon the sponge mixture on top of the plums and spread evenly. Bake for 45 minutes, or until a skewer comes out the middle of the cake clean and the sponge springs back to the touch. Leave the cake to cool slightly before turning out.

When you are ready to serve, gently release the cake from the tin. Place your serving plate on top of the sponge and flip the cake in one brave move.

As this is a very sweet and spiced cake, I would recommend serving it with a dollop of crème fraîche or natural yogurt. Enjoy!
