Makes about 2 dozen treats. The treats will keep for about a week. Freeze what you won't use in a week to give to your pup later.
Preheat the oven to 350 degrees F
Mash the bananas in a large bown
Add the peanut butter to the bananas and mix well.
Add the baking powder, flour and water and mix well.
Use a rolling pin to roll out the mixture until it is about 1/4" thick and then cut out the treat shapes using your cookie cutter.
Line a baking pan with parchment paper (or spray with non-stick spray). Then bake the treats for 10 minutes, flip the treats and then bake for another 10-15 minutes.
Let treats cool before serving.
