Mix all ingredients in a bowl.
PS: Xanthan gum is optional. It prevents the dough from becoming too crumbly.
Finally, add the yeast
Place the dough on a non-stick baking sheet (not too big - I used a 24cm diameter round) or greased with coconut oil and some flour or even with cinnamon.
Bake in a preheated oven at 180°C for approximately 30 minutes.
If you wish, cover or fill the cake with dulce de leche, to become the real churros cake!
