If you only make one homemade dog treat, make this one. These homemade peanut butter dog treats use four simple ingredients you probably already have: whole wheat flour, peanut butter, an egg and water. The dough rolls out easily, holds any cookie-cutter shape and bakes into a firm, crunchy biscuit with a toasty peanut smell most dogs love.
Below you will find the full recipe with weights and cups, step-by-step instructions, ways to make the treats softer or crunchier, ingredient swaps for wheat-sensitive dogs and clear storage times. There is also an important note about choosing a safe peanut butter, because not every jar on the shelf is dog-friendly.
Quick Facts
- Ingredients: 4
- Prep time: 15 minutes
- Bake time: 20–22 minutes
- Oven: 350°F (175°C)
- Yield: About 36 small bones (2 1/2 inch / 6 cm)
- Texture: Firm and crunchy; softer option included
Why These Peanut Butter Dog Treats Work
Most dog biscuit recipes rely on the same simple chemistry: flour for structure, a binder like egg, a fat for flavor and tenderness, and water to bring it together. Peanut butter does double duty here as both the fat and the flavor, so there is no need for oil, salt or sugar. Whole wheat flour adds fiber and a nutty taste, and a single egg keeps the dough cohesive so cut shapes don’t crack.
Because there is no leavening, the treats stay flat and dense. That makes them sturdy enough for treat pouches, easy to break into training pieces and less crumbly on the carpet than softer cookies.
Choosing a Dog-Safe Peanut Butter
This is the most important step. Some peanut butters, especially “sugar-free” or “reduced sugar” versions, are sweetened with xylitol, which is extremely toxic to dogs even in small amounts. Xylitol may also be listed as “birch sugar.” Always read the ingredient list.
- Best choice: peanut butter made from peanuts only, or peanuts and a little oil.
- Choose unsalted and unsweetened when you can.
- Avoid any jar listing xylitol, birch sugar or other artificial sweeteners.
- Avoid chocolate, honey-roasted or flavored spreads.
Smooth or crunchy both work. Crunchy gives a slightly more rustic biscuit, but smooth is easier to roll.
Simple 4-Ingredient Peanut Butter Dog Treats
Ingredients
- 2 cups (240 g) whole wheat flour, plus extra for rolling
- 1/2 cup (130 g) natural, unsalted peanut butter with no xylitol (check the label for “xylitol” or “birch sugar”)
- 1 large egg
- 1/2 cup (120 ml) water, plus 1–2 tbsp more if needed
Instructions
- Heat the oven to 350°F (175°C) and line two baking sheets with parchment paper.
- In a large bowl, whisk the peanut butter, egg and water until smooth. Natural peanut butter mixes more easily if you stir the jar well first.
- Add the flour and stir with a sturdy spoon, then knead by hand for about 1 minute until the dough is smooth and firm. If it is crumbly, add water 1 tablespoon at a time; if sticky, dust with a little more flour.
- Roll the dough to 1/4 inch (6 mm) thick on a lightly floured surface. Thicker dough gives chewier treats, thinner dough gives crisper ones.
- Cut out shapes with a bone cutter (about 2 1/2 inches / 6 cm) and place them 1/2 inch apart on the sheets. Re-roll scraps once.
- Bake for 20–22 minutes, rotating the pans halfway, until the edges are golden and the treats feel firm.
- For extra crunch, turn the oven off and leave the treats inside with the door cracked for 30–60 minutes.
- Cool completely on a wire rack before serving or storing.
Storage
Room temperature airtight for up to 2 weeks if fully crunchy; refrigerate softer treats up to 10 days; freeze up to 3 months.
Softer or Crunchier: How to Adjust the Texture
- Crunchier: roll to 1/8 inch (3 mm), bake the full time and dry them in the cooling oven.
- Softer: roll to 3/8 inch (1 cm), bake 16–18 minutes and skip the oven-drying step. Soft treats contain more moisture, so refrigerate them.
- Training size: roll 1/4 inch thick, score into 1/2 inch squares with a pizza cutter and bake as one sheet; snap apart after cooling.
Ingredient Swaps
- Oat flour instead of wheat: use 2 1/4 cups (200 g) and expect a slightly more tender biscuit.
- Pumpkin instead of egg: use 1/4 cup (60 g) plain unsweetened pumpkin puree.
- Banana for flavor: replace 1/4 cup of the water with 1 small mashed banana.
- Sunflower seed butter (unsalted, no xylitol) for dogs who don’t do well with peanuts.

Troubleshooting
Dough cracks when rolling: it needs a little more water. Knead in 1 tablespoon at a time. Treats puffed or spread: the dough was too wet or too warm; chill it for 15 minutes before cutting. Treats went moldy: they weren’t dried enough before being sealed. Dry them longer, or keep them in the fridge or freezer.
Ways to Use These Treats
Because the biscuits are firm and not greasy, they travel well in a pocket or treat pouch for walks and training. Break them into small pieces for repetitions, or keep whole bones for bedtime routines and vet visits. They also make a simple homemade gift: pack a dozen in a kraft paper bag, tie it with twine and add a small card listing the four ingredients so the recipient can check for allergies. For holiday gifting, cut the same dough into stars and trees, or try our cut-out Christmas cookie recipe with yogurt icing.
How Many Peanut Butter Treats Can a Dog Have?
Peanut butter is calorie-dense. Treats of any kind should stay under about 10% of your dog’s daily calories, so a small dog may get one or two of these per day and a large dog a few more. If your dog has a history of pancreatitis, weight problems or a nut allergy, ask your vet before adding peanut butter treats.
Dog Safety Notes
- Peanut butter: use only natural, unsalted peanut butter with no xylitol (check the label for “xylitol” or “birch sugar”). Choose unsalted and unsweetened.
- Never add: chocolate or cocoa, grapes, raisins or currants, onion, garlic, chives or leeks, macadamia nuts, nutmeg, alcohol, raw yeast dough, cooked bones, added salt or sugar, or artificial sweeteners.
- Fruit and veg prep: remove apple cores and seeds, use seedless watermelon without rind, and use plain unsweetened pumpkin puree (not pumpkin pie filling) and plain unsweetened yogurt.
- Portions: treats should make up no more than about 10% of your dog’s daily calories. Cut pieces to suit your dog’s size and supervise chewing.
- Check with your vet before introducing new foods if your dog has allergies, a sensitive stomach, diabetes, pancreatitis, kidney disease or is on a prescription diet. Introduce one new treat at a time.
Frequently Asked Questions
Is peanut butter safe for dogs?
Plain peanut butter without xylitol is generally safe in small amounts. Check the label for xylitol or birch sugar, and choose unsalted, unsweetened varieties.
Can I make these treats without flour?
Yes. Use 2 1/2 cups (225 g) rolled oats blended into flour, or try a flour-free banana and oat version from our three-ingredient recipes.
How long do homemade peanut butter dog treats last?
Fully crunchy treats keep about 2 weeks in an airtight container at room temperature. Softer treats should be refrigerated and used within 10 days, or frozen for up to 3 months.
Can puppies eat these peanut butter treats?
Many puppies can have small pieces once they eat solid food, but check with your vet first and break the biscuits into tiny portions.
