Prepare your silicone mold by laying it on a small baking sheet or something else that is stiff for easy transfer to the refrigerator.
Put all of the ingredients into a blender and blend until combined, approximately 2 minutes.
Pour the mixture into the molds.
Transfer the treats to the freezer (approximately 30 minutes) until set.
Pop the dog treats out of the mold and store in the freezer in a container or bag.
This is the dog silicone mold I used for this recipe. It comes with one bone shape (smaller) and one paw shape (larger). You can use any mold size and shape as preferred, however it will change the total number of treats you make in one batch. This batch is enough to fill both molds approximately twice for a total of 56 treats. The exact yield will vary with mold size and how large the bananas are.
