Plug in the Betty Crocker Mini Muffin Maker, and allow it to heat up. The indicator light turns green when it's ready.
Prepare your muffin mix. Pour the mix into the muffin cups, filling each only ¾ full. This allows room for rising.
Close the cover of the muffin maker, and allow the muffins to cook for three minutes. Then, allow them to cool for one minute. Remove the muffins, and place them on a cooling rack.
