In a food processor, pulse all the ingredients until a dough forms.
Separate the dough into 3 balls. Press down on each ball to form a 1-inch-thick disk. Wrap the dough in plastic wrap and chill for 1 hour.
Preheat the oven to 325°. Using a rolling pin, roll each disk out to ⅛ inch thick. Use a goldfish-shaped cutter to cut out the crackers and place them on a parchment-lined baking sheet. Reroll and cut the remaining dough scraps.
Bake for 15 to 20 minutes or until the goldfish begin to crack around the edges. Remove and let cool for 30 minutes before eating.
