I made mini muffins for my large English pointer and she absolutely loved them. I added 2 more tablespoons of apple sauce to make the mixture most moist and then packed them into the baking pan so they wouldn't crumble. I then baked them for 20 minutes and let them cool in the pan. I would definitely suggest mini muffins over the regular muffins because they are more manageable. This recipe made almost 60 mini muffins.
My dog loved this treat. He doesn't like carrots, but ate them in this treat. Make sure the cupcake is pressed together in the muffin pan, otherwise, it will fall apart when taking it out after it is baked.
