Lemon Blueberry Cupcakes

I had a jar of lemon curd to use up so I made up this recipe. Makes 20
100g Self raising flour
100g caster sugar
2 large eggs
100g butter
250g lemon curd
150g blueberries
200g mascarpone
Preheat oven 180C
Cream the butter and sugar together until light and smooth. Alternatively sift the flour and crack the egg in to the mixture and beat until smooth. Stir 100g lemon curd in to the mixture and 100g of the blueberries. You need to make sure you have 40 blueberries left to decorate the cakes. . Spoon the mixture in to cake cases and bake for about 15 minutes and golden brown.. While the cakes are cooling, mix together the mascarpone and the rest of the lemon curd. You want it to be marlbed so you can still see a swirl of lemon curd. Spread or pipe the mascarpone on to the cakes and put two blueberries on top of each one.
