Break up the bunnies and place in a glass bowl with cubed butter.
Melt in microwave for about 3 minutes on medium/medium high until chocolate and butter are both melted
Stir in sugar and mix well. Add in the eggs, mix well then the cointreau
Sift in the flour and gently combine
Pour into a lined or greased tin and bake in a preheated 160C/320F oven for 30 minutes until top is crispy. I did this in a silicon pan so don't grease the silicone or it gets too greasy.
Remove from oven and leave to cool completely. This is the important step. It will be really crumbly if you don't. So leave it. Just walk away. I know you want to eat it
When cool slice and enjoy
