Preheat oven to 350 degrees and line mini muffin cups with muffin liners.
Combine all ingredients well until you have a smooth batter with no lumps.
Using a small scoop, place about 1/2 tablespoon into each muffin liner. Do not overfill.
Bake for 6-8 minutes or until a toothpick inserted comes out clean.
Allow to cool slightly in the pan until you can handle them, then remove to a rack to cool completely.
Dust with a bit of flour, if desired.
Peel away the paper liner and allow your pet to enjoy!
