This Vietnamese dessert Tapioca and Mung Bean Cake (Banh Xu Xe / Banh Phu The) is visually intriguing with its translucent bright green color. For those unaccustomed to Asian desserts with an alien-green color, please try to overcome your apprehensions and give them a try. You will be pleasantly surprised! Pandan paste is what gives the cake its vibrant green color and floral aroma. Made of tapioca starch and filled with sweetened mung bean and coconut flakes, this steamed cake will satisfy your sugar cravings. The glutinous texture is rather unique and as a child I remember playing with the stretchy, sticky cake before eating it! Yes, to this day, I still play with my food! 🙂
The typical method of making the Tapioca and Mung Bean Cake is to roll individual cakes in plastic wrap and then steam. I am not entirely convinced that steaming food in plastic wrap is safe and so I’ve revamped the preparation. I use silicone baking cups lined with banana leaves. The banana leaves add lovely aroma and make cleaning the baking cups much easier. Tapioca starch is quite gluey and sticks to everything! If you don’t have banana leaves handy, use foil baking cups. I buy banana leaves in the freezer section of my Asian grocery store. To defrost, simply run the leaf under warm water. Then clean the banana leaves and cut to the needed size. For any remaining leaves, I place in a resealable plastic bag and pop it back in the freezer.

Tapioca and Mung Bean Cake / Banh Xu Xe / Banh Phu The
Place a banana leaf square on top of the baking cup and gently press the leaf inside the cup. Flip the cup over and trim the excess leaf with scissors. Continue lining all cups. Brush the banana leaves with the vegetable oil.
In a small bowl, combine all ingredients for the filling. Mix until a soft paste forms.
In a medium saucepan, add the tapioca starch, sugar, water, vegetable oil and Pandan paste. Whisk until the tapioca starch and sugar are dissolved and the mixture is smooth. Place the saucepan over Low heat and stir continuously. In 2-3 minutes, the mixture starts to thicken. Turn off the heat but continue stirring as sauce thickens and becomes a soft dough. When the dough starts pulling away from the saucepan, remove from the heat. Add the coconut flakes and stir quickly, blending well.
Spoon a tablespoonful of dough into the cup. Add a teaspoon of filling in the center. Add another spoonful of dough on top. Spread the dough evenly in the cup. Continue with these steps making the remaining cakes.
Steam the cakes for 15 minutes over Medium High heat.
Remove from the steamer and allow to cool for at least one hour before serving.
To serve, peel off the banana leaf (and discard) and enjoy the Tapioca and Mung Bean Cake as finger snacks.
