1whole orangpeel and pulp, around 260g – untreated, preferably organic
300gflour
200gsugar
16gbaking powder
3eggs
100mlvegetable oil
185mlboiling water
50gunsweetened cocoa powdersifted
80-100gchocolate chipsoptional
Instructions
Grease and flour a 23cm cake tin or use baking paper.
Preheat the oven at 180/160 (fan assisted)
Sift the cocoa powder into a bowl and whisk in the boiling water until it has all dissolved and there are no lumps. Set aside to cool.
Wash the orange and cut in quarters. Take all the seeds out (if any are present), then chop everything into small pieces, including the peel, and put it in a food processor to reduce it to a pulp.
Transfer the resulting pulp into a bowl, add the eggs and sugar, and beat for a few minutes until you get a light texture.
Add vegetable oil, cocoa mixture, baking powder and flour and whisk until everything gets incorporated. Bear in mind that you won't get a smooth texture, but it will look grainy due to the orange peel.
Add the chocolate chips if using.
Pour everything into the prepared tin and bake in the oven for 50/60 minutes, or until a skewer comes out clean. Check a few times towards the end, as you do not want to overbake to retain that beautiful moisture.
Let it rest for a while (if you can resist temptation) and enjoy!
If you want to turn this into muffins, just divide the batter into muffin cases and cook for 15-18 minutes. Time will vary depending on the size of the muffins; of course, every oven is different.
