"The word 'pyramid' actually comes from the Greek word 'pyramis' which means 'wheat cake'. The word 'pyramis' was used to describe the ancient Egyptian buildings because they reminded the Greeks of pointy-topped wheat cakes. "

Maybe the wheat-cake was styled after the pyramid. Didn't the pyramids come first?
