Homemade Peanut Butter Banana Dog Treats (Gatsby’s Treats)
There are few things Gatsby loves more than a treat—especially one that comes straight from my kitchen! These homemade Peanut Butter Banana Dog Treats are made with just four familiar ingredients: bananas, peanut butter, whole wheat flour and water. They take only minutes to prep, and I love knowing exactly what’s tucked inside every bite I give my girl.

As a nutritionist and devoted dog mom, I’m always mindful of ingredient labels—even when I’m baking for Gatsby. Be sure to choose a natural peanut butter made primarily with roasted peanuts and always check that it contains no xylitol or other sugar substitutes, which can be dangerous for dogs. If you have extra bananas and more peanut butter hanging around after making your pup’s batch, you can put them to use in my Peanut Butter Banana Protein Pudding, Frozen Banana Snickers, Single Serve Jumbo Oatmeal Cookie, and PB Banana Cereal Bowl for the humans in the house.
It’s a pawsome feeling to make doggie treats from scratch
- Just four simple ingredients. You know exactly what’s going into every bite.
- Easy to customize. Swap the mashed banana for plain pumpkin, sweet potato or butternut squash purée.
- Soft or crunchy—you decide. Bake for about 20 minutes for a tender, chewy texture or longer for a firmer biscuit.
- Perfect for playful shapes. Silicone molds turn the batter into bones, paws and other charming creations.
To shake things up, you can also swap in pureed sweet potato, butternut squash or pumpkin for the mashed banana if you’d like. I bake mine in the oven for just 20 minutes to create a softer and chewier texture for Gatsby, as she recently had a few of her teeth pulled (apparently, this is common for Cavachons; her cousin Stewie has been dealing with teeth issues as well).
For harder, crunchier treats you can leave them in the oven for 40-50 minutes or so. When they’re done, I like to keep a bunch on the counter in a sealed container for a few days, and then transfer into the fridge for about a week… the rest I stash in the freezer, which keeps them fresh for about 4 months.
You can purchase a few baking molds in fun doggie-style shapes at local pet shops, home stores, or buy them online here. Then you’re all set to make the ulti-mutt treats for your furry four-legged lovebugs!

Homemade Peanut Butter Banana Dog Treats (Gatsby’s Treats)
Ingredients
- 2 bananas, mashed
- ½ cup water
- 1 cup creamy peanut butter*
- 1 cup whole wheat flour
- A pinch of cinnamon, optional
Instructions
- Preheat the oven to 350°F. Place silicone dog-treat molds on a baking sheet for stability.
- Add the mashed bananas, water, peanut butter and cinnamon, if using, to a large mixing bowl. Stir until smooth and well combined.
- Add the whole wheat flour and mix until a thick, evenly blended batter forms.
- Spoon the batter into the molds, filling each cavity to the top. Use the back of a spoon or a small spatula to spread the batter into the corners and smooth the tops.
- Bake for about 20 minutes for softer, chewier treats. For firmer, crunchier biscuits, continue baking for 40 to 50 minutes total, checking periodically toward the end so they don’t become overly browned.
- Allow the treats to cool in the molds for 5 to 10 minutes. Gently remove them and transfer to a wire rack to cool completely.
- Store in an airtight container in the refrigerator for up to 1 week. For longer storage, freeze for up to 4 months and thaw individual treats as needed.
