Using an electric mixer beat the butter and sugar until light and fluffy
Mix in the vanilla essence and golden syrup
Add the cocoa, a little flour and the baking powder and combine
Add little bits of flour until you form a firm but pliable dough
Roll out the dough, about half a millimeter thickness and cut into shapes. I used a small square cutter
Place the cookies on a parchment lined cookie sheet and refrigerate for 30 minutes
Preheat oven to 160 degrees Celsius
Bake cookies for 8 minutes or until you can smell them. They will still be a little soft when removed from the oven
Cool the cookies on a wire rack
Melt the chocolate in the microwave, 20 second increments. Dip each cookie into the chocolate, one side only. Place them on parchment paper on a flat tray and freeze for 10 minutes
Sandwich the cookies together with more melted chocolate
You can add some melted chocolate to a zip lock bag and snip a tiny hole in one corner. Drizzle the chocolate on one side of the cookie. This final step is optional
