Preheat oven to 375°F. Grease the kuih bahulu molds.
Beat the eggs with an electric hand-mixer until frothy and then add sugar. Continue to beat until the sugar is well dissolved and the mixture becomes sticky.
Add in the vanilla essence and fold in the flour gradually and then add in the cooking oil/butter. Continue to beat the batter with the hand-mixer until well-blended. Pour the batter into the molds filling them to the top. (I recommend slightly below surface level as these cakes do puff up)
Bake for about 15 minutes or until golden brown. Remove bahulu from the molds and cool on wire racks. Dust with powdered sugar, if desired.
