Beat the whites in a solid white mass. Put in the refrigerator. Butter or margarine to mix with sugar and egg yolks. Add rum and cinnamon.

To the dough add chocolate, nuts, baking powder and crackers.

Gently stir in the protein mass, don't try this dough will be airy.

Roll the cherries in flour. Put the dough in the form, I silicone soaked with cold water, and the iron covered with parchment paper, lay on top of cherries and press down lightly with your hands or mix with the dough, as you like. Bake at 200°C for 25-30 minutes (in an iron form on the cakes will take longer).

Then sprinkle with powdered sugar and decorate to your liking (not repeat!) kidding!!!
