In modern English “crape” refers to thin, crinkled paper or cloth. Black crape was traditionally associated with mourning. A crepe is a thin flat French pancake. Most Americans pronounce the two words the same, to rhyme with “ape.” If you want to spell it the French way, you’ll need to add a circumflex over the first E: crêpe, and pronounce it to rhyme with “step.” Even if you use the French form you’re likely to sound the final S in plural crêpes, though a real French speaker would leave it silent.
