It's a lovely cake, very nice warm, and also really excellent on the second or third day. I found it here. Now, I've never met a cake I didn't like, but this is certainly one of my favourites:
Rhubarb Sour Cream Cake
60g softened butter
300g brown sugar
1 teaspoon of vanilla extract
Grated zest of one lemon
2 eggs
150g plain flour
150g self raising flour
1 teaspoon cinnamon
350g sour cream
One bunch of trimmed rhubarb (around 350g), cut into 1cm slices
50g brown sugar, extra
1 teaspoon cinnamon, extra
Prepare a 24cm springform tin by lightly greasing, then lining the base and sides with baking paper, extending a few cm higher than the sides of the tin.
Beat together the butter, brown sugar, vanilla and lemon zest until very well combined.
Beat in the eggs, then stir through the dry ingredients with the sour cream.
Fold through the rhubarb.
Carefully spread the mixture into the prepared cake tin, smoothing the top.
Sprinkle the combined extra brown sugar and cinnamon generously over the top of the cake - it will be a thick coating.
Bake at 160 degrees for around 1 1/4 hours, or until a cake tester comes out clean from the middle.
Allow to cool a little in the tin, then serve either warm (with custard!) or at room temperature with cream.
