The Classic pairs a 4.5-quart stainless steel bowl, which is dishwasher safe and has no handle, with 10 speeds on a slide control. The planetary action touches the bowl in 59 points, and the tilt-head locks while you mix. KitchenAid rates it for up to 8 dozen cookies per batch with the flat beater. It comes in two colors, white and black.

No source publishes a hard flour capacity for this bowl. We treat it as a small-batch to moderate-dough machine.
How We Tested
We judged it on motor strain, vibration, noise, stability and cleanup, using whipped cream, batters, cookie dough, soft pizza and white bread dough, plus one dense whole wheat loaf.
For every recipe, we monitored motor noise, head vibration, base stability, and the amount of unmixed flour or cream left at the bottom of the bowl.
