Prepare the ingredients: Mix each color layer according to the ingredient sections above.

Steam or cook the mung beans until soft, then blend with sugar until smooth. Mix the tapioca starch with coconut milk from section 1.3, then combine with the blended mung beans to make the yellow layer. For the green layer: mix all ingredients from 1.1 together. For the pink layer: mix all ingredients from 1.2 together.

Set up a steamer on the stove. Lightly oil the cake pan and heat it. Pour in a layer of green or pink batter, cover, and steam until set. Then pour in a layer of yellow batter. Repeat the process, alternating layers, until all the batter is used.
