Plum & hazelnut upsidedown cake recipe

This was featured in this week's "Waitrose Weekend" guide. I was impressed that even for someone who's rubbish at baking or following recipes properly, it turned out perfectly moist and spongy. So I decided to share it here. I couldn't find the recipe on the www.waitrose.com/recipe website, so even typed up the whole thing here, happy baking!

Prepare 20minutes
Cook 45minutes
Serves 8 (or a greedy couple over the weekend :-p)

Ingredients
125g butter
50g light muscovado sugar (I accidentally used brown granulated sugar, but seems to work)
50g roasted chopped hazelnuts (couldn't find them so used flaked almonds instead)
1 tsp ground cinnamon
6 Plums, stoned and quartered (make sure they are ripen, some of mine were a bit sour...)
75g golden caster sugar
Grated zest of 1 orange
1 large free range egg, beaten
150g self-raising flour
1/2 tsp bicarbonate of soda
100ml Soured Cream

1. Preheat the oven to 180C, gas mark 4. Butter and base line a 20cm round deep cake tin. Melt 50g of the butter and mix with the muscovado sugar, hazelnuts and cinnamon. Scatter over the base of the cake tin and press the quartered plums into the base.

2. Beat the remaining butter with the caster sugar and orange zest until pale and creamy (is it me or should this specifically say melt the butter first?), then beat in the egg a little at a time (again, shouldn't it say beat the egg first, THEN add a bit at a time?). Sift the flour with the bicarbonate of soda and fold into the creamed mixture with the soured cream to give a soft consistency. Spoon on top of the plums and level the surface.

3. Bake for 45-50 minutes until well-risen, golden and firm to touch. Cool in the tin for 15minutes, then turn onto a wire rack. Serve warm with cream or cold. Store in an airtight container.
