I start by placing 12 or however many you need for portion sizes chocolate orange segments on a plate and in the freezer.
Preheat your oven to 180 C/350 F/Gas Mark 4
Then begin the brownies by melting 225 grams of butter and the 270 grams dark cooking chocolate over a very gentle heat in a medium size saucepan. Be careful that the chocolate does not burn on the bottom of the pan.
When nearly all the chocolate is melted remove from the heat and stir until it is all smooth.
Tip in 400 grams of sugar and stir for a few minutes until the sugar has begun to disappear and become less grainy in the chocolate mixture.
Add in the 4 beaten eggs and the 1 tsp of orange extract and again mix well until smooth.
Finally add 175 grams flour, mix very well until shiny. I then add the rest of the chocolate orange pieces cut up into chunks and mix through.
Tip the chocolate orange brownie batter into your lined baking tin.
Bake for 25 minutes
Place the orange segments in regular spaces on top of the brownie. Gently press them just into the surface of the brownie crust and place back in the oven for another 5 minutes.
Leave to cool completely in their tin before cutting into your portion sizes for however you want to partition them up.
