You may need to add some additional flour depending on the size of your avocado, so keep some extra on hand.
Preheat oven to 350º
Turn out onto a parchment lined surface and roll to an even 1/4 inch thickness.
Cut out and place on parchment lined cookie sheet.
Bake for 20-25 minutes or until just browned around the edges.
You can turn off the oven and leave cookies inside to cool slowly, creating a crunchier dog treat.
