Here in Mexico, we eat "Rosca de reyes" on January. It is a cake like bread with figs and other sweet things on top. Usually it has little plastic dolls inside and if you get one you make tamales on February
Wikipedia says: "Rosca de Reyes" or Three Kings Cake. In Mexico and Guatemala however, the person who finds the doll in their piece of rosca must throw a party on February 2, "Candelaria Day," offering tamales and atole (a hot sweet drink thickened with corn flour) to the guests.
Rosca de reyes or roscón de reyes (kings' ring) is a Spanish and Spanish American king's cake pastry traditionally eaten to celebrate Epiphany.
Although the name indicates that it should be round, the “rosca de reyes” generally has an oval shape due to the need to make cakes larger than 30cm across for larger parties. Recipes vary from country to country. For decoration, fig fruit, quinces, cherries or dried and candied fruits are used.
It is traditionally eaten on January 6, during the celebration of the "Día de Reyes" (literally "Kings' Day"), which commemorates the arrival of the three Magi or Wise Men
