Complete loss of avionics during flight. Checked circuit breaker and all were in. Cycled avionics power switch several times. Made the decision to fly back to ZZZ without communications knowing that the Tower would keep traffic out of the way. Radios came back on all of the sudden while on a short final. Informed the Tower of the issue. Controller did ask why I didn't squawk 7600; I told him the transponder was inoperative as well.
C172 pilot reported complete loss of avionics power. The pilot elected to perform an air turn back and precautionary landing at departure airport.
