Peanut Butter & Banana Cookies: A Classic Combo for Happy Pups

Let’s be honest—dogs love peanut butter almost as much as we do, maybe even more. After more than 20 years of living with dogs, grooming them daily, and preparing homemade treats, I’ve seen firsthand how peanut butter instantly grabs a dog’s attention. Add banana to the mix, and you’ve got a treat most dogs go wild for.

I’ve made these Peanut Butter & Banana Cookies countless times for my own dogs and for clients’ pups after grooming sessions. They’re simple, nutritious, and made with ingredients I trust—no fillers, no mystery additives, just real food dogs enjoy.

Ingredients: Simple, Nutritious, and Drool-Worthy

Here’s what you’ll need to make these classic dog cookies. I stick to these ingredients because they’re gentle on digestion and widely recommended by vets for homemade dog treats.

1 cup oat flour – Oat flour is easy to digest and naturally gluten-free, making it a great choice for dogs with sensitive stomachs.
1/2 cup natural peanut butter – Packed with protein and healthy fats. Always ensure it contains no xylitol, which is toxic to dogs.
1 ripe banana, mashed – Provides potassium, fiber, and natural sweetness.
1 egg (optional) – Adds protein and helps bind the cookies together for a firmer texture.

From my experience grooming senior dogs, oat flour and banana are especially helpful for dogs with delicate digestion or dental sensitivity.

Instructions: Making Peanut Butter & Banana Cookies in 5 Easy Steps

These cookies are as easy to make as they are for dogs to eat. I’ve taught this recipe to dozens of dog parents who wanted a reliable, no-fail treat.

Step 1: Preheat Your Oven

Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper to prevent sticking and make cleanup easier.

Step 2: Mix It Up

In a large bowl, combine oat flour, peanut butter, mashed banana, and egg if using. Stir until a thick dough forms. If the dough feels sticky, add a bit more oat flour. If it’s dry, add a small splash of water.

Step 3: Shape the Cookies

Roll spoonfuls of dough into small balls and gently flatten them with your fingers or a fork. Place them evenly on the baking sheet.

Step 4: Bake

Bake for 15–20 minutes until the cookies are firm and lightly golden. In my experience, slightly longer baking creates a crunchier cookie, which many dogs prefer.

Step 5: Cool and Serve

Allow the cookies to cool completely before serving. This helps them firm up and prevents mouth burns—especially important for small dogs.

Why These Ingredients Are Perfect for Your Pup

Each ingredient serves a purpose beyond taste.

Oat Flour – Provides slow-burning energy and fiber while being gentle on the stomach.
Peanut Butter – Supplies protein and healthy fats that support skin and coat health.
Banana – Rich in potassium, vitamin B6, and fiber for muscle and nerve support.
Egg – Adds high-quality protein and improves texture.

Veterinary nutrition guidelines recommend treats stay under 10% of a dog’s daily calorie intake, which these cookies support when portioned properly.

Storing the Goodies

Proper storage keeps these cookies fresh and safe.

In the Fridge – Store in an airtight container for up to 7 days.
In the Freezer – Freeze for up to 3 months. I often freeze half the batch and thaw as needed.

Serving Suggestions: Anytime, Anywhere

Over the years, I’ve used these cookies in many ways.

Training Treats – Break into small pieces for positive reinforcement.
Snack Time – Offer as an occasional between-meal treat.
Meal Topper – Crumble over food to encourage picky eaters.

FAQs

Q: Can I use a different flour?
