Apple Peanut Butter Oat Cookies

Makes About 18 small cookies · 40 minutes total

Ingredients

  • 1 medium apple, cored and deseeded, then grated (about 1 cup)
  • 3 tablespoons plain peanut butter, xylitol-free and unsweetened
  • 1 1/2 cups (about 150 g) rolled oats, half blitzed into a coarse flour
  • 1 egg
  • 1-2 tablespoons water, only if the dough is too dry

Instructions

  1. 1Check the peanut butter label: it must not contain xylitol, and ideally no added sugar or salt.
  2. 2Heat the oven to 180°C / 350°F and line a baking tray with parchment paper.
  3. 3Quarter the apple, cut out the core and remove every seed, then grate the flesh. Squeeze out excess juice.
  4. 4Stir the grated apple, peanut butter and egg together, then mix in the oats and oat flour to a thick dough.
  5. 5Shape rough tablespoon-sized cookies by hand and flatten them slightly on the tray.
  6. 6Bake for 22-25 minutes until firm and lightly browned, then cool completely on a wire rack.

Storage

  • These contain fresh fruit or egg and no preservatives, so they belong in the fridge in an airtight container, not on the counter. Refrigerate within 2 hours of cooking, or within 1 hour if the room is above 32 °C (90 °F), and split a warm batch into shallow containers so it chills quickly.
  • A storage life has not been established for this recipe. Make small batches, and freeze the portions you want for later at −18 °C (0 °F) or below. Thaw in the fridge, never on the counter.
  • Harmful bacteria can be present without any change in smell or appearance, so time and temperature decide, not how a treat looks. Discard anything left in a warm room too long, or kept past these limits — chilling or freezing does not make mishandled food safe.

Serving considerations

  • These cookies are occasional treats, not a meal and not a complete and balanced diet.
  • Peanut butter is calorie-dense, so keep portions small and count treats as part of daily intake.
  • Serving amounts vary with your dog's size, health and normal diet — ask your vet what suits your dog.
  • Apple seeds and core should always be removed, and never add sugar, honey, salt, chocolate or artificial sweeteners.

Frequently Asked Questions

Check the ingredients list for xylitol, sometimes listed as birch sugar, and avoid it entirely. Plain peanut butter with no sweeteners or salt is the best choice.

Peeling is optional — the skin is fine. What matters is cutting out the core and removing every seed before grating.

There is no need. These cookies work without added sweeteners or spices, and keeping the ingredient list short keeps them suitable as a treat.

The apple may have released less moisture than usual. Add water a spoonful at a time until the dough just holds together when pressed.

Keep them small and occasional. Peanut butter is calorie-dense, so the right number depends on your dog's size, health and normal diet.
