Start by peeling 2 ripe tangerines.
Cut them in half and into smaller pieces.
Next, cut 2 more ripe, unpeeled tangerines in the same way.
Transfer them all to a medium bowl, add the eggs and put everything in a blender.
Add the sugar, the natural yogurt, the vegetable oil, a pinch of salt and blend everything very well until smooth.
Transfer this mixture to a large bowl, passing it through a sieve, add the wheat flour and mix to combine.
Add the baking powder and mix once more.
Transfer all this batter to a 20cm diameter cake pan greased with butter and wheat flour.
Take to a preheated oven at 180° C (350° F) and bake for 45 minutes.
Finish by brushing tangerine juice all over the cake and sprinkling grated coconut to taste.
Serve.
