- 250 g (9oz) plain flour, plus extra to dust
- 125 g (4oz) unsalted butter, chilled, cut into cubes
- 125g (4oz) caster sugar
- 2 Tbsp. golden syrup
- 50 g (2oz) cocoa powder
- 1 tsp. bicarbonate of soda
- 3 Tbsp. milk
For the filling
- 75 g (3oz) unsalted butter, softened
- 125 g (4oz) icing sugar
- 15 g (1/2oz) cocoa powder
- Step 1
Preheat oven to 180°C (160°C fan) mark 4. Put all the biscuit ingredients into a food processor and pulse until the mixture clumps together. Tip the dough on to a work surface and bring together.
- Step 2
Roll out the dough on a sheet of baking parchment, trying to keep it rectangular and dusting your rolling pin with flour as needed, then trim to a 23cm x 30.5cm (9in x 12in) rectangle. Cut the rectangle lengthways into 3 even strips, keeping strips together, then cut across them at 2.5cm (1in) intervals, keeping the rectangles together. If you like, use the end of a skewer to mark the long edges of each biscuit with five dots to resemble a traditional Bourbon. Chill for 30min.
- Step 3
Bake for 25min, then carefully remove the tray from the oven and cut through the marks to make sure biscuits are separated. Leave to cool completely.
- Step 4
To make the filling, put the butter into a large bowl and sift in the icing sugar and cocoa powder. Mix until combined (don't be tempted to add any liquid - the icing should be thick).
- Step 5
Sandwich the cooled biscuits together with the chocolate filling, using a piping bag if you want a neater finish.
