UPSIDE DOWN ORANGE CAKE

This is a really nice cake for for the Christmas holidays. Really simple to make and properly seasonal. We also make a version of this with pineapple when it isn't Christmas.
You need:

- one and a half oranges
- 2 handfuls of brown sugar
- 150 gr brown sugar
- 150 plain flour
- a teaspoon of baking powder
- 150 butter
- 2 eggs
- grated zest of and orange

Preheat the oven at 180 degrees.

Take a round cake tin. Sprinkle the 2 handfuls of brown sugar over it. Slice the oranges thinly (the thickness of a pound coin or a bit less) and arrange them nicely over the sugared tin. Separately beat the sugar and batter, then add the zest and eggs and keep beating it. Finally add the flour and baking powdered and fold it into the mixture. Put this batter over the oranges - the batter is a bit thick to absorb the water of the oranges, so you may need to spread it a bit to cover the whole tin. Bake in the oven for 30 minutes.

When you take it out of the oven wait for 5-7 minutes, run a knife around the edges and then unmould it carefully. It  should come out easily. It is very nice with unsweetened greek yogurt.
