Preheat the oven to 375.
Grease cookie sheets.
In a large bowl, mix together the cake mix and flour. Stir in the eggs and water to form a stiff dough.
On a lightly floured surface, roll the dough out to 1/4 to 1/8 inch thickness.
Cut into 3-4 inch round circles and place 2 inches apart onto the prepared cookie sheets.
Place a teaspoon of filling into the center of each cookie and pinch the sides to form three corners.
Moisten with water if necessary.
Bake for 6-8 minutes in the preheated oven, or until lightly browned.
Allow cookies to cool for 1 minute on the cookie sheets before removing to wire racks to cool completely.
Yes, this recipe calls for a cake mix but it's one that can be whipped up in about 3 minutes and the kids can do it without any supervision.
