- Preheat your oven to 300F (150C). Line a baking sheet with parchment paper.
- Add the oats to a food processor and grind until they reach a fine powder. (If you do not have a food processor, see the recipe notes for other options). Add the bananas and peanut butter and blend until a sticky dough is formed.
- Remove from the food processor and roll out on a lightly floured surface. (Use whole wheat flour, more ground oats, or another dog-safe flour that you have on hand). I used a heart cookie cutter to cut out the treats but you could use any cookie cutter, or just cut them into squares with a knife or pizza cutter.
- Lay the treats on the prepared baking sheet and bake for 25 to 30 minutes, until the treats are puffed up a bit, dry and dark brown on the bottoms, (they will still feel soft when first removed from the oven). The treats will get a bit more firm once they are cool but will still be a slightly softer dog treat. Let cool before giving one to your pup. Store in an air-tight container at room temperature for up to 1 week, in the fridge for up to 2 weeks, or I like to store them in my freezer which makes them firmer and makes them stay fresh a long time.
