Servings dog treats

There’s something special about baking for your pup—watching their nose twitch as the treats come out of the oven, and the excitement when they realize they’re for them. These banana dog treats are one of my go-to recipes: they’re easy to make, require just three pantry staples, and are guaranteed to earn you some serious tail wags.

Three ingredients for banana dog treats: bananas, creamy peanut butter, and old-fashioned oats.

I started experimenting with homemade dog treats years ago, after being frustrated with long ingredient labels. Most of the time, I just wanted something simple, something I could whip up quickly when bananas were getting too ripe on the counter. These easy-to-make treats have since become a staple in my house.

⚠️ Important Note: Always check with your veterinarian before introducing any new food or treat into your dog’s diet, especially if they have allergies, sensitivities, or existing health conditions.

Ingredient Notes

Bananas – The riper the better; they mash and blend smoothly into the dough.

Oats – Old-fashioned oats are ground into flour for the base. Keeping a little extra oat flour aside makes rolling easier.

Peanut Butter – ⚠️ Go with creamy peanut butter that’s free from xylitol (a sweetener that’s unsafe for dogs).

Substituting Old Fashioned Oats With Pre-Made Oat Flour

If you don’t have old-fashioned oats, you can use pre-made oat flour as a direct substitute. Since our recipe starts with 3 ½ cups rolled oats, that equals about 2 ¾ cups oat flour.

Note – Dough with pre-ground oat flour can sometimes be softer. If it feels too sticky to roll, just add a little more oat flour (1 tablespoon at a time) until it’s workable.

After baking, the treats should feel dry on top. For crunchier biscuits, leave them in the oven with the door cracked open for another 10–15 minutes to cool slowly.

Storage Tips

Room temperature: Airtight container for 2–3 weeks (depending on texture).

Freezer: Up to 2 months. Just thaw at room temperature before serving.

I usually keep a jar on the counter for everyday use and freeze a backup batch so I’m never out of treats.

Ingredients

3 ½ cups Old Fashioned Oats, I used Great Value brand
3 medium-size ripe bananas
½ cup creamy peanut butter, I used Jif brand

Instructions

Preheat the oven to 350*F. Line a baking sheet with parchment paper.
Add the oats to a food processor and grind/blend the oats for 2- 2 ½ minutes, or until the oats are ground into oat flour.Reserve ½ cup of the oat flour for sprinkling your work surface.
Add the bananas and creamy peanut butter to the oat flour in the food processor. Pulse until the bananas and peanut butter are well incorporated with the oats. (You are looking for a firm yet pliable texture for the dough)
Sprinkle some of the reserved oat flour over your work surface.
Turn the dough out on top of the sprinkled oat flour.
Use a rolling pin to roll the dough out to ¼ inch thickness.
Use the cookie of your choice (I used a bone shaped cookie cutter, but you can use any cookie cutter shape or simply slice into small squares)
Place the cookie cut outs onto the parchment paper lined baking sheet 1 inch apart. Bake for 20 minutes for a crispy dog treat, or 15 minutes for a softer dog treat.
Allow the treats to rest on the baking sheet for a few minutes before transferring to a cooling rack to completely cool. Once cooled, you can serve immediately.

Notes

Store any leftover treats in an airtight container at room temperature. You can store the softer dog treats for up to 2 weeks, and you can store the crispier treats for up to 3 weeks. You can store the completely cooled dog treats in an airtight container for up to 2 months. You can allow the treats to thaw overnight at room temperature before serving.
You can substitute oat flour for the Old fashioned ground oats. You can substitute crunchy peanut butter for the creamy. Make sure that whatever brand of peanut butter you choose does NOT contain Xylitol. Xylitol is toxic to animals.
