Bánh Chuối Hấp is a cherished Vietnamese dessert, especially loved in the lively Mekong Delta of Southern Vietnam (Miền Tây). This steamed banana cake is wonderfully soft, chewy, and fragrant, bursting with tropical flavors in every bite.
Slice the bananas into thin rounds, about 0.1 inches (2-3 mm) thick.
In a bowl, gently toss the banana slices with sugar, salt, and turmeric powder. Let this mixture sit for 5 minutes to bring out the flavors.
Sprinkle in the tapioca starch and flour, then mix gently until fully incorporated, with no visible white spots.
Gradually pour in the hot water, stirring gently until smooth and well-combined. Finally, add the cooking oil and mix until everything is fully blended.
Lightly grease a baking pan (a silicone pan works well) with cooking oil. Pour in the banana mixture, spreading it evenly across the pan.
Steam the cake on medium-high heat for 25-30 minutes. Check if it's done by inserting a toothpick—it should come out clean, with no batter sticking to it.
Let the cake cool completely before cutting it into parallelogram-shaped pieces for serving.
Sweet Coconut Sauce
In a pot, warm the coconut milk, sugar, salt, and pandan leaves, stirring until everything is blended.
Slowly pour in the tapioca starch slurry, stirring constantly over medium-low heat until the sauce thickens and starts to simmer.
Serve the cake with a generous drizzle of coconut sauce, then sprinkle with crushed peanuts or toasted sesame seeds for extra flavor!
