Preheat your oven to 190C/180C Fan/375F and line three baking trays with parchment paper
Mix together the butter and sugars until light and fluffy and thoroughly combined – I often use an electric mixer for this bit as it makes it so much easier and combines the ingredients very well – but good ol’ manpower will work too!
Add the vanilla essence and the beaten egg, and mix again briefly.
Add the cocoa powder, flour, bicarbonate of soda, baking powder, salt and orange and mix until a thick paste/cookie dough is formed. (Or add it all in together!)
Chop the chocolate orange pieces and add to the mixture and fold through
Spoon the mixture onto the trays and make sure they are suitably spread out so they stay separate! (I usually fit 6 on each tray to be safe) I also use a cookie dropper/ice cream scoop to make them identical sizes.
Bake in the oven for 10 minutes – remove quickly and add a segment to each cookie, and then bake for another 1-2 minutes.
Once baked, remove from the oven and allow to cool slightly before gobbling up otherwise you might burn yourself on molten chocolate!
Notes
You don’t have to add the chocolate pieces on top, you can include it all in the dough, but I love having melted bits of chocolate on top of a cookie – especially if I am serving them warm with a drink, such a gooey chocolate treat!
If you don’t have Terry’s chocolate orange where you are, you could try using milk chocolate with a bit more orange zest, or even a bit of orange flavouring which I often do!
These cookies will last for 4-5 days+, but usually, get eaten before that.
