These cookies are so incredibly rich that you'll only need to have one to get your chocolate fix for the day. The dark chocolate gives the biscuits a bittersweet taste, whilst the orange filling gives that little bit of sweetness that all cookies should have. Want to bake them? Course you do, they're brill.
For the biscuits - 225g of broken dark chocolate, 75g of plain four, 1/4 teaspoon of baking powder, two eggs, 100g of sugar, the grated zest of one orange & a pinch of salt
For the filling/icing - 75g of unsalted butter, 100g of sugar & the grated zest and juice of one orange.
Makes approximately seven cookies (after you sandwich them together).
Preheat the oven to 180°C (gas mark 4).
Melt the chocolate using a double boiler. Sieve the flour, baking powder and salt into a bowl. In a different bowl (multiple bowls, betcha didn't see that one coming) whisk the eggs, sugar and orange zest, then stir in the melted chocolate and flour. The mixture should be thicker than cake batter, but not doughy - add a bit more flour if necessary. Spoon the mixture onto an oiled tray (I managed to fit six blobs to a tray) and bake for 15-20 minutes.
Whisk the filling ingredients until fluffy. Spread on the base of a biscuit and sandwich another on top (I had to wait until the biscuits had cooled down before I attempted this step, as if the cookies were warm they would've melted the butter in the filling and it would've been a complete mess). You can also leave out the filling altogether, and you're left with plain chocolate orange cookies -there's twice as many to go around as well!
