Grease and line cake tin or prepare muffin tins for cupcakes.
220 ml water
175gms butter - chopped
120gms sugar (I have used either castor and brown with good results)
200gms chocolate - chopped (use the highest cocoa content you can afford)
70gms defrosted frozen berries - mashed with a fork
2 eggs - lightly beaten with a fork
125gms Self Raising flour
Combine water, butter and sugar in a bowl, either heat over a saucepan of boiling water or in a microwave till butter melts and water boils.
Add chopped chocolate and stir till smooth and melted.
Add lightly beaten eggs and whisk gently till smooth.
Finally stir through the mashed berries. (You can use fresh berries if they have enough flavour, I've also successfully used mashed banana and chopped black cherries)
Finally pour mixture (yes, pour...it's very liquid so don't worry - you havn't done anything wrong) into the desired tin or dish. I recently used this recipe to make a pudding (which I poured butterscotch sauce over to serve) and it worked extremely well.
