If you want the cake to have a firmer structure, add 1/2 cup of wheat flour. Many dogs are sensitive to wheat, so you should only do this if you know your dog can safely eat wheat products. If your dog like sweeter treats, you can also add 2 teaspoons apple juice. Don’t add extra sugar or salt, since it’s not good for your dog.
You know best what your dog finds tasty. Feel free to add a handful of other vegetables your dog likes to “sweeten” the cake for him or her. You could also add herbs for some gourmet flair. Add a tablespoon of chopped parsley if you know your dog likes the taste.
