Preheat the oven to 350°F and line a muffin tin with paper liners or lightly grease the cups.

Cook the ground beef in a skillet over medium heat until no pink remains, breaking it into small crumbles as it cooks. Drain off all excess fat and let the beef cool slightly.

In a large mixing bowl, whisk together the egg, applesauce or yogurt, and water until smooth.

Add the oat flour, shredded carrots, parsley, and turmeric to the bowl and stir until a thick, scoopable batter forms.

Fold the cooked ground beef into the batter, mixing just until it is evenly distributed.

Spoon the batter into the prepared muffin cups, filling each one about 3/4 full.

Bake for 25 minutes, or until the muffins are set, lightly golden, and a toothpick inserted in the center comes out clean.

Remove the pan from the oven and let the muffins cool in the tin for 5 minutes, then transfer them to a wire rack to cool completely before serving to your dog.
