Peanut Butter Banana Dog Biscuits (Easy 4 Ingredient Recipe) -

Peanut butter and banana is a classic pairing for a reason. Dogs love the nutty, sweet flavor, and the ripe banana does double duty, adding natural sweetness and holding the dough together so you don’t need eggs or oil.

These biscuits are made with just four ingredients, roll out like cookie dough, and bake into a sturdy, crunchy treat that’s perfect for training, rewards, or tossing in a gift jar.

If you want a softer, chewier version, try my Banana Peanut Butter Chew Sticks for Dogs.

For a twice baked treat with berries, see my Banana, Peanut Butter, and Blueberry Dog Biscotti. This post is the simple, classic cut out biscuit, and it’s the easiest of the three.

Why You’ll Love These Biscuits

Only four ingredients. Flour, banana, peanut butter, and water or broth.

No eggs, no added sugar. The ripe banana provides sweetness and binding.

Easy to roll and cut. Use any cookie cutter, from bones to hearts.

Crunchy and long lasting. Baked low and dry, they keep well.

Great for training. Cut them small and they make perfect rewards.

Before You Start: Important Safety Notes

Check the peanut butter for xylitol. Xylitol, also listed as birch sugar, is highly toxic to dogs and shows up in some “sugar free” or specialty peanut butters.

Read the full ingredient list every time. If your dog eats anything containing xylitol, call your veterinarian or an emergency clinic immediately.

Choose plain, unsalted peanut butter. Look for a simple ingredient list with just peanuts, or peanuts and a little salt. Avoid added sugars and flavorings.

Treats are not a meal. Treats should be a small part of your dog’s daily diet. Peanut butter is rich and high in fat, so keep portions modest, especially for small dogs and dogs prone to pancreatitis.

Introduce slowly. Any new food can upset a dog’s stomach. Start with a small piece.

Check with your veterinarian. Ask before feeding new treats to puppies, seniors, dogs with allergies, and dogs with health conditions such as diabetes, since bananas contain natural sugar.

Watch for allergies. Peanut allergies are uncommon in dogs but possible. Stop feeding and call your vet if you see itching, swelling, vomiting, or diarrhea.

Ingredients You’ll Need

Each ingredient has a job.

Whole wheat flour. Gives the biscuits structure and a hearty bite. If your dog avoids wheat, oat flour or brown rice flour works. See the variations below.

A ripe banana. The spottier, the better. Ripe bananas are sweeter and mash more smoothly. Bananas are a safe, popular treat for most dogs in moderation.

Natural peanut butter. Adds flavor and fat that makes the dough easy to work with.

Water or low sodium broth. Adjusts the dough as needed. If you use broth, make sure it has no onion, garlic, or added salt. My How to Make Carrot Frozen Bone Broth for Dogs shows a safe homemade version.

Ingredient List

2 cups whole wheat flour, plus extra for rolling
1 large ripe banana, mashed
1/4 cup natural, unsweetened peanut butter, xylitol free
1/4 cup water or onion free, unsalted broth, added a little at a time as needed

How to Make Peanut Butter Banana Dog Biscuits

Preheat the oven. Heat to 350°F (175°C). Line a baking sheet with parchment paper.
Mash the banana. Use a fork in a large bowl until smooth with no big lumps.
Add the peanut butter. Stir until the mixture is creamy and evenly combined. If your peanut butter is stiff, warm it for a few seconds first.
Add the flour. Stir in the flour a little at a time. The dough will be thick and crumbly.
Add liquid. Add water or broth a tablespoon at a time until the dough comes together into a firm ball. It should be stiff, not sticky.
Knead briefly. Turn the dough onto a floured surface and knead for about a minute.
Roll it out. Roll to about 1/4 inch thick.
Cut the shapes. Use cookie cutters, or cut the dough into squares with a knife or pizza cutter.
Arrange on the tray. Place the biscuits about 1/2 inch apart. They barely spread.
Bake. Bake for 20 to 25 minutes, until the edges are golden and the biscuits feel firm.
Dry them out for extra crunch. Turn off the oven, leave the biscuits inside with the door slightly ajar for an hour or two, and let them dry out.
Cool completely. Cool on a rack before serving or storing. They crisp up more as they cool.

Texture Tips

For a crunchier biscuit. Roll thinner, bake a few minutes longer, and let them dry in the cooling oven.

For a softer biscuit. Roll a little thicker and shorten the baking time. Store soft biscuits in the refrigerator.

If the dough is too dry. Add water or broth, one teaspoon at a time.

If the dough is too sticky. Add a little more flour until it’s easy to handle.

For even baking. Keep every biscuit the same thickness.

Variations

Oat flour version. Replace the whole wheat flour with 2 cups oat flour. Grind plain rolled oats in a blender to make your own. The dough may be a little stickier.

Grain free version. Use a grain free flour such as chickpea flour or coconut flour, though coconut flour absorbs much more liquid, so add water gradually.

Ask your veterinarian before changing your dog’s diet, as grain free is not necessarily better for every dog.

Pumpkin twist. Replace half the banana with plain pumpkin puree, not pie filling. See my Pumpkin Banana Dog Treats.

Mini training treats. Cut tiny squares and bake for a shorter time, then check for crispness.

Peanut butter drizzle. Melt a small spoonful of xylitol free peanut butter and drizzle over cooled biscuits for a special occasion.

Seasonal shapes. Use holiday cookie cutters for gifts and parties.

Common Mistakes to Avoid

Using peanut butter with xylitol. Always read the label.

Using an underripe banana. The dough will be less sweet and harder to mix.

Adding too much liquid. Sticky dough is hard to roll. Add liquid slowly.

Rolling too thick. Thick biscuits stay soft in the center and spoil faster.

Skipping the cooling step. Biscuits crisp as they cool, so don’t judge them straight from the oven.

Storing them while warm. Trapped steam makes biscuits soggy and moldy.

Overfeeding. These are treats, so keep portions small.

How Many Can My Dog Have?

It depends on your dog’s size, weight, and activity level, and on the rest of their diet. As a general guide, treats should make up only a small part of daily calories.

Small dogs may only need a piece of a biscuit, while larger dogs can have one or two. If you’re not sure, ask your veterinarian for a treat allowance.

Storage

Room temperature. Fully dried, crunchy biscuits keep in an airtight container for about a week.

Refrigerator. Store in an airtight container for up to two weeks. Soft biscuits should always go in the fridge.

Check before serving. Discard any biscuits with mold, an off smell, or an unusual texture.

Freezing

Freeze baked, completely cooled biscuits in a freezer bag for up to three months. Thaw at room temperature or in the refrigerator before serving. You can also freeze the raw dough, wrapped tightly, then thaw in the fridge before rolling.

Frequently Asked Questions

Can dogs eat bananas? Yes, in moderation. Bananas are a popular, low risk treat for most dogs, but they contain natural sugar, so keep portions small and ask your vet if your dog has diabetes or weight problems.

Is peanut butter safe for dogs? Plain peanut butter without xylitol is generally safe in small amounts. Always check the label, since xylitol is dangerous.

Can I make these without flour? Not easily, since the flour provides structure. For a flourless treat, try my Banana Dog Treats or a frozen option.

Can I use a different nut butter? Some nut butters are safe, but macadamia nuts are toxic to dogs, and some mixes contain xylitol. Stick to plain peanut butter unless your veterinarian says otherwise.

Are these safe for puppies? Ask your veterinarian first. Puppies have sensitive stomachs and specific nutritional needs.

Why are my biscuits soft? They may be too thick, underbaked, or not dried enough. Bake longer and let them dry in the cooling oven.

Can I use overripe bananas? Yes, very ripe bananas work well, as long as they aren’t moldy.
