Preheat oven to 350. Using your food processor (or high speed blender), blitz your oats into a flour.
Whisk together pumpkin and egg till smooth.
Using a spatula, stir in peanut powder. Finally stir in oats. This will be a very thick dough.
Using a small disher, scoop onto parchment lined sheets. Flatten with slightly wet fingers.
Bake for 30 minutes, then reduce heat to 300. Bake an additional 15 minutes, then turn off oven and allow treats to fully dry out. (Alternately, you can keep them as soft, chewy treats for older doggies by pulling them out after the initial 30 minutes. Just know that these soft treats will need to be refrigerated for freshness.)
Notes
Can be made into soft treats for older dogs by removing after initial 30 minute bake. Please note that these will need to be refrigerated for freshness. They will last up to a week in a sealed container in the fridge
Dry dog treats should be stored in an airtight container (preferably with a leftover packet of silica from a box of shoes or a bag of beef jerky) in a cool, dry spot. They'll last indefinitely if they are baked until fully dry and protected from humidity and pests.
OPTIONAL DECORATING: Feeling extra? To make these seasonal treats look like pumpkins, you can create Jack o' Lantern faces using a toothpick (for the eyes) and a spork (for the smile).
These are not intended to replace your dog's normal meals! Please use them responsibly.
