2cFlouryou could use a whole wheat or other flour, but it will alter the color slightly. Whole wheat also give them more body. I really don't think the dogs will mind :
1/8tspBaking soda
2mashedvery ripe Bananas
2Tbl Unsweetened Applesauce
2Tbl Warm water
All natural food coloring
Instructions
Preheat oven to 350 degrees.
Combine all ingredients except food color in the bowl of an electric mixer. Blend to form a dough that will hold together in a ball. If your dough is too moist, add more flour. Too dry? Try adding more applesauce. The dough is very forgiving.
Roll the dough to about 1/4". They will puff up when baked.
Cut into shapes using miniature Easter shaped cookie cutters. These are about 1-1/2" cutters. You can get these on Amazon.com or at most craft stores that carry baking supplies. I think even Walmart might carry them in this small size.
You can also get the bags there as well.
Arrange cookies on a parchment or Silpat lined cookie sheet.
Bake for 5-6 minutes until they are just set and move easily on the cookie sheet. Do not let them brown.
Reduce the heat of the oven and once it's at the lowest setting (175 degrees), continue to bake until completely dry. We are basically dehydrating the cooking removing all of the moisture so they are crunchy and have some shelf-stability. Any moisture that remains could cause them to mold after a few days. If you are unsure, take one of the thickest cookies and snap it in half to test. I usually turn the oven off at this point and let them cool in the dry residual oven heat overnight.
Allow to cool completely before giving to your pup! :)
