Preheat your steamer
Beat eggs, sugar and emulsifier for 7 mins, until fluffy and pale
Beat in flour and milk, alternating one after another
Divide batter into two, stir pandan paste to one, and mocha paste to the other
Scoop batter into individual molds that have been lined with cupcake wrapper (can be alternating color, can be separately, can be marbled, it’s up to you)
Steam for 15 mins, wrap steamer lid with clean towel to avoid water drips
