Discover Baking Kit: Chocolate Sandwich Biscuit

Before you start:
Keep 1 tbsp of the flour and cocoa blend from the bag (for dusting).
Cover 2 baking trays with baking parchment.
Carefully cut out both the square and round templates.

Combine the caster sugar, flour & cocoa blend in a bowl with a spoon.  Chop the butter into cubes and add to your mixture.  Rub in the butter with your fingertips (until it looks like breadcrumbs), then form a ball with your chocolatey dough.

Dust your surface with the 1 tbsp of the flour & cocoa blend you’d set aside earlier and roll out the dough to the thickness of a £1 coin.  Lightly press the square template onto the dough and carefully cut around it using a cutlery knife.  Remember to cut a window with the round template in half of the biscuits.  Put each biscuit onto your baking tray and leave them to chill in the freezer for 20 mins.

Pre-heat your oven to 180C/160C/Gas 4 and bake your biscuits for 10 mins.  Remove from the oven and place your biscuits on a cooling rack.  They’ll soon harden up.

Make the buttercream by mixing together the icing sugar, butter and milk until smooth.  Then, when the biscuits are cool, pair them together by spreading buttercream onto one side of a whole biscuit and topping it with a biscuit with a window in it.  Now decorate the window with sprinkles!
