A powder dispensing apparatus for storing and dispensing a measured predetermined amount of powder substance having a bottom housing chamber, a middle chamber, a removable, rotatable measuring device, a tapered top chamber, and a cap. The top end of the bottom housing chamber is engageable with the bottom end of the middle chamber, the top end of the middle chamber is engageable with the bottom end of the tapered top chamber, and the top end of the tapered top chamber is engageable with the cap or a liquid receptacle. The measuring device is slidably engageable with the internal chamber of the middle chamber and has an open cavity for measuring and dispensing a powder substance. The open cavity receives a measured predetermined amount of powder substance from the bottom housing chamber and upon rotation of the measuring device; the powder substance is dispensed from the open cavity through the tapered top chamber to a liquid receptacle. The measuring device has a locking tooth and spring mechanism which engages with the locking ring of the middle chamber.
