A portable coffee brewing mug apparatus for brewing and consuming fresh coffee on the go includes a cup body. A cup riser tube extends from a cup top perimeter down through a cup sidewall and into a cup interior adjacent a cup base. A heating element powered by a cup battery is coupled within the cup base. A brewing module is selectively engageable with the cup body and has a pod holder to secure a coffee pod. A module riser tube is in fluid communication with the cup riser tube and a drip tube to bring heated water from the cup body onto the coffee pod. A base body has a base top side selectively receiving the cup base. A charger is coupled within the base body and is in operational communication with the cup battery.
