1-First Step: Get ready: Preheat the oven to 300°F (150°C) and line a baking sheet with parchment paper. Gather your ingredients and decide whether you will use a food processor, blender, or coffee grinder to make oat flour. Having a lightly floured surface ready (whole wheat flour or extra oat flour) will speed up rolling.

2-Second Step: Make oat flour: Place the 2 cups oats in your food processor, blender, or coffee grinder and grind until a fine powder forms. This makes a soft oat flour that binds better than whole oats. If you do not have a processor, pulse in batches in a sturdy blender or coffee grinder and sift to remove large bits.

3-Third Step: Mix the dough: Add the 2 medium ripe bananas and 1/2 cup natural peanut butter to the ground oats. Blend or process until a sticky, uniform dough forms. You want it to hold together but not be overly wet. If it feels too loose, add a tablespoon of oat flour at a time.

4-Fourth Step: Roll and shape: Remove the dough and place it on a lightly floured surface. Use whole wheat flour, more oat flour, or another dog-safe flour as needed to stop sticking. Roll the dough to about 1/4-inch thick for a good balance between crisp and soft. Cut into shapes with a cookie cutter or a knife. For training treats, small shapes are ideal. Transfer the shapes to the prepared baking sheet, spacing them slightly apart.

5-Fifth Step: Bake: Lay the treats on the baking sheet and bake for 25 to 30 minutes until puffed, dry, and dark golden brown on the bottoms. They will be slightly soft when removed but will firm up as they cool. Keep an eye on them toward the end so they do not over-brown.

6-Final Step: Cool and store: Let the treats cool completely on a wire rack before giving any to your dog. Storing warm treats traps moisture and can lead to spoilage. Store in an airtight container: up to 1 week at room temperature, 2 weeks in the fridge, or longer in the freezer.
