This is fab showstopper that I picked up from Facebook and goes down a storm in the office
185g unsalted butter
185g best dark chocolate
85g plain flour
40g cocoa powder
3 large eggs
275g golden caster sugar
6 cadbury's Crème Eggs, cut in half
Preheat the oven to 160c and grease a 20cm square baking tin.
Melt the butter and dark chocolate together either in the microwave or in a bowl over hot water.
Break 3 large eggs into a large bowl and tip in 275g of golden caster sugar. With an electric mixer on maximum speed, whisk the eggs and sugar until they look thick and creamy, like a milkshake! This can take 3-8 minutes. TIP, you'll know its ready when the mixture becomes pale and about double it's original volume.
Pour the cooled chocolate mixture over the eggy mousse, then gently fold together.
Hold a sieve over the bowl of eggy chocolate mixture and sift the cocoa and flour mixture, shaking the sieve from side to side, to cover the top evenly. Gently, fold in the mixture.
Pour into the baking tin and cook for 15 minutes then take it our of the oven and gently press the Cadbury's Crème Egg halves into the mix spacing them apart evenly. Put back in the oven for another 5-10 minutes.
Leave to cool before removing from the tin and cutting.
