Preheat your oven to 300
Mash the bananas: Peel the bananas and place them in a bowl. Then use either a potato masher or a fork, and mash the bananas into a puree.
Mix ingredients in a bowl: Add the mashed bananas along with the other ingredients to a large bowl. Then use either your hands or a spoon to mix the ingredients together to make our dough.
Flatten the dough: Get out either a piece of parchment paper or a silicone mat, and place it flat on your kitchen counter. Sprinkle a little bit of flour over it, and then place the dough in the middle. (You might have to do this step along with step 5 in two separate batches). Next use a rolling pin to flatten out the dough, until it’s about a ¼ inch thick.
Cut the dough: Use any shaped cookie cutter you want (my mom loves the dog bone shape one). After you have cut out the dog treats place them on a cookie sheet that has been covered with either parchment paper, or a silicone mat (it will make clean up a lot easier).
Bake the treats: Place the treats in your heated oven to bake for 20 minutes.
Let them cool off before giving to your dog.
