If you love spoiling your pup but hate complicated recipes, you are going to love these 3 Ingredient Banana Oat Dog Biscuits. I make these when I want something quick, healthy, and budget friendly.
No preservatives. No mystery ingredients. Just simple pantry staples that you probably already have at home.
These homemade dog treats are soft, naturally sweet, and perfect for training rewards or an afternoon snack.
Plus, you control exactly what goes into your dog’s body. That alone makes this recipe worth trying.
Why Make Homemade Dog Biscuits?
Store bought treats often contain artificial flavors, added sugars, salt, and fillers. Even “natural” brands sometimes include preservatives that are not ideal for daily use.
When you bake your own homemade dog biscuits, you get:
- Full control over ingredients
- No artificial additives
- Better digestion for sensitive dogs
- Cost savings over time
- Fresh treats made with real food
I personally started baking for my dog after noticing mild stomach issues from commercial treats. Switching to simple, whole food recipes made a big difference in digestion and energy levels.
If your dog has a sensitive stomach, homemade treats like these can be a gentle option.
Ingredients for 3 Ingredient Banana Oat Dog Biscuits

The beauty of this recipe is simplicity. You only need three wholesome ingredients.
1. Ripe Bananas
Use ripe bananas with brown spots. They are softer, sweeter, and easier to mash.
Benefits of bananas for dogs:
- Rich in potassium
- Contains vitamin B6
- Provides vitamin C
- Supports muscle and nerve function
- Natural energy source
Bananas should always be fed in moderation due to natural sugar, but in treat form like this, they are perfectly safe.
2. Rolled Oats
Use plain rolled oats or old fashioned oats. Do not use flavored or sweetened oatmeal packets.
Oats are:
- A good source of fiber
- Gentle on digestion
- Helpful for dogs with wheat sensitivities
- Packed with important minerals like iron and magnesium
If your dog is sensitive to gluten, oats are a great alternative to wheat flour.
3. Peanut Butter
Use natural peanut butter that does not contain xylitol. Always check the ingredient label carefully.
Peanut butter provides:
- Healthy fats
- Protein
- Vitamin E
- B vitamins
Avoid any brand containing artificial sweeteners. Xylitol is toxic to dogs, even in small amounts.
Step by Step Instructions
Making these banana oat dog biscuits is quick and beginner friendly.
Step 1: Preheat the Oven
Preheat your oven to 350°F or 175°C. Line a baking sheet with parchment paper.
Step 2: Mash the Bananas
In a mixing bowl, mash 2 ripe bananas until smooth. A fork works perfectly.
Step 3: Add Peanut Butter
Add 1/2 cup of natural peanut butter. Mix until fully combined.
Step 4: Add Oats
Stir in 2 cups of rolled oats. Mix until a thick dough forms. If the mixture feels too sticky, you can chill it for 10 to 15 minutes.
Step 5: Shape the Biscuits
You can:
- Roll small balls and flatten with a fork
- Use cookie cutters for fun shapes
- Press into silicone molds
I usually make small bite sized pieces for easy portion control.
Step 6: Bake
Bake for 12 to 15 minutes for softer treats. If you prefer crunchier biscuits, bake for 18 to 20 minutes.
Let them cool completely before giving one to your dog.

Nutritional Benefits of Banana Oat Dog Treats
These healthy dog treats are not just tasty. They also offer real nutritional value.
Fiber for Digestive Health
Oats contain soluble fiber, which helps regulate bowel movements and supports gut health. If your dog occasionally struggles with mild constipation, fiber can help.
Natural Energy Boost
Bananas provide carbohydrates that give your dog a quick energy boost. This makes these biscuits great before a walk or play session.
Healthy Fats for Skin and Coat
Peanut butter contains healthy fats that support shiny fur and healthy skin. You may even notice improved coat softness over time.
Remember, these are treats, not meal replacements. Treats should make up no more than 10 percent of your dog’s daily calorie intake.
Portion Control and Feeding Guidelines
Even healthy treats should be given responsibly.
For small dogs:
- 1 to 2 small biscuits per day
For medium dogs:
- 2 to 3 small biscuits per day
For large dogs:
- 3 to 4 small biscuits per day
If your dog is on a weight management plan, adjust portions accordingly. You know your dog best, so always monitor their response.
Storage Tips
Proper storage keeps your homemade dog biscuits fresh and safe.
Room Temperature
Store in an airtight container for up to 3 days.
Refrigerator
Store for up to 7 days in a sealed container.
Freezer
Freeze for up to 3 months. I like to freeze in small batches so I can pull out just what I need.
Let frozen treats thaw before serving.
Optional Add In Ideas
While this recipe works perfectly as is, you can safely customize it.
Safe add ins include:
- Finely grated carrots
- Pumpkin puree
- Chia seeds
- Unsweetened applesauce
Start with small amounts and test your dog’s tolerance. Keep the base simple if your dog has a sensitive stomach.
Common Mistakes to Avoid
Here are a few things I learned the hard way.
Using peanut butter with xylitol: Always double check the label. Even a small amount can be dangerous.
Adding sugar or salt: Dogs do not need added sweeteners or salt in treats.
Overbaking: If baked too long, the biscuits can become too hard, especially for senior dogs.
Skipping portion control: Even healthy treats contain calories.
Why Your Dog Will Love These
Dogs naturally love the smell of peanut butter. When combined with sweet banana and hearty oats, the result is irresistible.
These 3 Ingredient Banana Oat Dog Biscuits are:
- Soft enough for puppies and seniors
- Easy to break into training treats
- Made from human grade ingredients
- Free from artificial additives
I have found that homemade treats also strengthen the bond between you and your dog. There is something satisfying about baking something special just for them.
