You could use cream makeups purchased from the store, but make sure you set them with lots of powder to prevent the cream from smearing off. Also, I would suggest a witch chin that can be painted with the makeup. I would use greens for the base and contour. Purples/lavenders on the eyes. I used to work at Disneyland and had a friend who was cast as Maleficent.
