Method:
In a bowl, mix the rice flour with the yogurt, sweetening the mixture.
You will need to get a small dough that can be easily worked with your hands.
Divide the dough in two and on one half add 3 grams of unsweetened cocoa powder.
Roll out the two loaves between two sheets of parchment paper and with the help of a pastry cutter create two circles (one white and the other black).
In the oven at 180 ^ for 20/25 minutes.
Once cooled, stuff with yogurt and let it rest in the fridge.
