Chocolatey, crunchy yet chewy at the same time and stuffed with coconut - they're lethal as you cannot stop at one!
Collect together your equipment (see Recipe Notes below) and ingredients.
Preheat oven to Fan Oven 160°C /180°C/350°F/Gas 4
For the base: melt the butter and syrup in a large saucepan over a moderate heat, until melted.
Add the cocoa and beat with a balloon whisk until no lumps remain.
Crush the Weetabix to make fine crumbs (I just use my hands) and add to the butter mix with all the remaining ingredients.
Mix thoroughly and tip into your lined baking tin. Level and flatten the surface, making sure you push the mixture into all the corners. Prick the base allover with a fork.
Cook in the centre of the pre-heated oven for 25 - 30 minutes.
Take out of the oven and leave to cool in the tin.
Top with Chocolate: melt the chocolate and butter in a bain marie or in the microwave. (See comments below). Spread evenly over the coconut base.
Optional: sprinkle some sea salt where you imagine the centre of each square will be.
Leave to set in the baking tin and put it in the fridge for roughly an hour. Cut into 16 squares.
Equipment:
Be very careful melting the chocolate. Chocolate can be very difficult to work with. You can overheat it very easily and the mixture will go grainy.
Microwave: I give the chocolate and butter a minute in the microwave, take it out and stir it well, then let it sit for a few minutes to see if it continues melting sufficiently to melt all the chocolate. If not, I then continue with the microwave but in 10 – 15 second bursts.
Bain Marie: if you do not have a microwave, put the chocolate and butter in a heatproof bowl over a saucepan of gently simmering water. Do not let the base of the bowl touch the water. Heat until the chocolate and butter are very nearly melted then take it off the heat and take the bowl off the saucepan. Be very careful not to burn yourself as the bowl will be hot and steam will escape from the saucepan. Allow the mixture to sit for a few minutes for the residual heat to melt the remainder of the mixture. Again, be careful not to over-heat.
