🐾 Why Go Homemade Instead of Store-Bought?
Before we dive into the recipe, let’s address the big question: Why bother baking dog treats at home when you can just buy them?
Here’s why thousands of dog parents are switching to homemade:
- No hidden nasties → Commercial treats often hide salt, sugar, soy, or xylitol (toxic for dogs).
- Customizable → You control portion size, texture, and add-ons.
- Budget-friendly → Costs a fraction of premium store treats.
- Health-focused → Perfect for dogs with allergies, sensitive stomachs, or picky appetites.
- Bonding time → Your dog will literally watch you bake, tail wagging the whole time.
Now, let’s bake some cookies your pup won’t stop begging for!
🥣 Ingredients: Simple, Safe & Nutritious

- 1 cup rolled oats – Fiber-rich, helps with digestion, gentle on the tummy.
- ½ cup natural peanut butter (xylitol-free) – Protein, healthy fats, irresistible flavor.
- ½ ripe banana (mashed) – Natural sweetness, potassium boost, acts as a binder.
🔥 Upgrade Options (Optional Add-ins for Variety)
Want to make them extra special? Try these vet-approved add-ins:

👩🍳 Step-by-Step Instructions
1. Preheat the Oven
Set your oven to 350°F (175°C). Line a baking sheet with parchment paper (or lightly grease with coconut oil).

3. Mix It Up
In a bowl, combine oats, peanut butter, and mashed banana. Stir until it forms a sticky dough. If dry, add a splash of water; if too sticky, sprinkle in oat flour.

5. Bake
Bake for 15–20 minutes, until golden brown and slightly firm.
