These homemade cake mixes are made from wheat seed grown in Kansas, then ground into flour. The fruits and vegetables are purchased locally and then dehydrated so when you add the liquid ingredients to the mix, the fresh flavors are activated to get the best flavor possible for your pet. This recipe works in the microwave so fits in well with a busy lifestyle. However, for those who like the aroma of freshly baked treats, you can make in your oven as well. The flavors available are: Apple, Blueberry, Carrot, Carob, Pumpkin, Sweet Potato, and Plain (for those who want to add a flavor like peanut butter, cheddar, or other).
