The KitchenAid stand mixers that have the largest bowl sizes are the Commercial Series 8-quart, bowl-lift mixers, as of 2015. An 8-quart capacity is enough for over 13 dozen cookies and allows users to make cakes, dough and other baked goods in bulk quantities.
Models KSM8900B and KSMC895ER are certified by the National Sanitation Foundation and have stainless steel bowls. These are also two of the most powerful KitchenAid stand mixers with 1.3-horsepower motors. For users looking for a mixer strictly for residential use, KitchenAid manufactures bowl-lift and tilt-head stand mixers that range in size from 5 to 7 quarts.
