Homemade Liver Brownies: Irresistible Dog Treat Recipe

Looking to pamper your dog with a tasty, nutrient-packed snack? These iron-rich Liver Brownies are an easy homemade treat your pup will adore.

Made with real organ meat and simple pantry staples, these liver bites are a wholesome way to reward your dog.

Most dogs don’t need iron supplements, and a small boost of iron from liver treats is fine for healthy pets. If your dog has medical conditions, check with your veterinarian before adding new treats to their diet.

Will they smell? Yes—liver has a strong scent while baking. If you’re sensitive to meaty aromas, you may notice it more than others. To me it smells like a rustic meatloaf baking, not pleasant but tolerable if you know what to expect.

Liver Brownie Ingredients

Here’s a quick overview of what you’ll need. Exact measurements and step-by-step instructions are in the recipe card below.

• Oats
• Whole wheat flour
• Coconut oil, flax oil, or peanut butter – if using coconut oil, melt it first.
• Liver – chicken, beef, duck, turkey, or game livers all work. (This recipe used duck and turkey livers.)
• Eggs
• Optional: Turmeric

Iron toxicity from these treats is unlikely—dogs would need to eat large quantities of concentrated vitamins for that to be a concern. Still, consult your vet if your dog has health issues or dietary restrictions.

Tools You Will Need

A food processor makes this recipe easiest. You’ll also want a rubber spatula, a 9×13-inch baking dish (or an 8×8 for thicker treats), parchment paper, and a baking sheet.

How to Make Homemade Liver Treats

1. Preheat the oven to 325°F and line a baking dish with parchment paper.
2. Prepare the livers: usually this means removing them from packaging. For wild game, clean any debris and check for shot.
3. Grind the oats in a food processor until they reach a flour-like texture. Transfer the oat flour to a bowl.
4. Add the livers, eggs, and oil to the food processor and puree until smooth and slightly runny. Hold the lid securely—it may vibrate while processing.
5. Add the wheat flour, oat flour, and turmeric (if using). Process briefly, then scrape the sides with a rubber spatula to incorporate any splatters and ensure an even mix.

6. Pour or spoon the batter into the lined baking dish and smooth into an even layer.
7. Choose your pan size based on desired thickness: a 9×13-inch pan yields thinner treats, and an 8×8-inch pan will produce thicker brownies and may need longer baking time.
8. Optional: clip the parchment to the pan sides to keep it from folding while you work.

9. Bake at 325°F for 35–40 minutes, then remove from the oven.
10. Let the baked loaf cool for a few minutes. Lift the parchment with the loaf onto a cutting board.
11. While still on the parchment, cut the loaf into bite-sized squares suited to your dog’s size.

12. Transfer the parchment with the cut treats to a baking sheet and return to the oven for 10–15 minutes to crisp them up.

13. Remove the treats from the oven and allow them to cool completely.

14. Serve to your dog and enjoy watching them savor these nutritious bites.

Variations

• Training treats: cut into very small pieces for quick rewards.
• Soft treats: skip the second bake. Bake only once for about 40 minutes. Store these soft treats in the refrigerator or freezer, as they retain moisture and can spoil faster.

Substitutions

• Match proteins to your dog’s needs—use beef if your dog is allergic to chicken, or vice versa.
• Short on liver? Add other organ meats like heart, kidneys, or gizzards. Mixing offal works well and adds nutrition variety.

Storage

These treats are preservative-free, so I recommend storing most in the freezer and keeping a few days’ worth in the refrigerator for convenience.

Keep refrigerated portions in an airtight container or mason jar. Frozen treats thaw quickly and still hold together well for serving.
