Your problem is operator error. You need to meter for the moon.
Set your metering mode to spot metering, and point the camera directly at the moon, and shoot.
Alternatively, use manual mode and the sunny 16 rule as a starting point - that's ISO 100, f/16, 1/125th, if it's a little dull increase the exposure by opening the aperture wider, if too bright then use a narrower aperture.

If you are metering the frame in matrix mode, the camera will see a lot of black and think the scene needs a long exposure. This will overexpose the moon.
You need to spot meter on the Moon, or as it s a sunlit object, use the sunny 16 rule (shutter speed = 1/ISO @f16

Problem is that you are relying on auto exposure and auto exposure breaks dwon in difficult high contrast shots like this. Your camera sees all that black sky and decides it is dark so it ramps up the exposure to bring the black sky to mid grey.
To correct it, Set the exposure to under-expose by at least 3 stops.
