Pre-heat your oven to 180C Fan/400F/Gas Mark 6, and line a few baking trays (or however many you own) with baking paper
Ideally using a stand mixer with the paddle attachment, mix the dairy free butter, caster sugar and light brown soft sugar together until fluffy and paler in colour. This will take 3-5 minutes in an electric mixer (I use speed 3)
Add the dairy free milk, orange zest and orange extract, and mix them in
Add the plain flour, cocoa powder, baking powder, bicarbonate of soda and salt and mix them in until just combined
Add the chocolate chips, mix briefly, just to evenly distribute them
Divide the dough into portions, I weighed the dough out to make each cookie an equal size. For 14 cookies I used 63g dough per cookie
Roll balls of the cookie dough between your hand, flatten them a little and place onto your lined baking trays, leave space between the cookies (at least 2") as they will spread a little bit
Bake the cookies for 12-14 minutes, remove from the oven and place a piece of dairy free chocolate orange on top of each one, then leave to cool on the trays for at least 10 minutes before moving to a cooling rack (or eating!)
Store leftovers in an airtight container and eat within 3 days
