preheat oven to 450°

mix flour, milk, salt and melted butter in a bowl

add one egg and mix thoroughly then add the next egg and mix thoroughly

fill greased pan (pop over pan or muffin pan works too) each section should be about 3/4 filled with mixture

put pan in the oven for 15minutes then lower temperature to 350° for another 20minutes (depending on your oven, some only need about 16 minutes)

DO NOT OPEN THE OVEN DOOR UNTIL DONE COOKING otherwise the pop overs will collapse
