Beat egg slightly in a bowl; add in oil, water and hotcake mix. Stir just until slightly lumpy (Do not overmix). Set aside.
Prepare a 2 x 2 inches ring made from aluminum foil. Grease with oil and place on a preheated slightly greased pan or flat skillet.
Pour about 2 tablespoons of mixture into the ring. When about to set, put a teaspoon of ube jam in the center and cover with a small amount of hotcake mixture.
Cook for a few minutes then turn to cook the other side.
