I've seen this chocolatey sweet being generally sold at most of bakery and coffee shops in England for years but I didn't bother to find out what it really was until the last time I visited my husband's family when it was nicely made and served by my sister-in-law!
When I was given the recipe, I noticed it was a kid's handwriting, then my sister-in-law told me that it's her daughter who wrote the recipe which was from her husband's mother..it's handed down from generation to generation, so no wonder why it's sooo scrumptious !
The Recipe ( slightly adapted from the original ) :
75g unsalted butter
a tbsp caster sugar
75g cocoa powder
75 g dark chocolate ( 70% cocoa )
1 tbsp golden syrup
100 g sultanas + raisins
225 g crushed digestive biscuits
340 g ( a whole bag ) semi-sweet chocolate chips
Melt the first 5 ingredients in a saucepan on a low heat. Let cool for few minutes. In a mixing bowl, combine the last 2 ingredients and mix in the butter and choco. mixture. Stir until everything evenly distributed. Press the mixture into the prepared tin ( 7*11 inches , lightly grease the bottom and line with parchment paper ), cover with foil and leave in the fridge for few hours until firm ( I left overnight ).
Melt the semi-sweet choc. chips and spread evenly over the top. Let cool again until the topping set. Slice into pieces and enjoy !
