In a food processor, combine all the ingredients. Pulse until the mixture resembles coarse meal. Then process continuously until the dough comes together.
Form a ball, cover with plastic wrap and set aside for about 30 minutes.
Turn the batter out onto a floured work surface and divide in half. With well-floured hands, shape into two logs.
Using a knife, cut the dough into small squares. Pattern each cookie with a fork.
Preheat an oven to 325°F. Place the Panderos on the cookie sheet, about 1 inch apart.
Bake until light brown, about 15 minutes. Transfer the baking sheet to a rack and let the Panderos cool on the sheet for 5 minutes. Transfer them to the rack to cool completely. Store in an airtight container at room temperature.
