Preheat the oven to 350 degrees F (175 degrees C). Line a 10x15 inch jellyroll pan with parchment paper.

Place the liver into a food processor. Pulse until finely chopped. If you have room, add the flour and eggs, and process until smooth. Otherwise, transfer to a bowl, and stir in the flour and eggs using a wooden spoon. Spread evenly in the prepared pan.

Bake for 15 minutes in the preheated oven, or until the center is firm. Cool, and cut into squares using a pizza cutter. The treats will have a consistency similar to a sponge. Store in a sealed container in the refrigerator.
