Learn how to make Bánh cam at home! This traditional Vietnamese treat consists of sweet mung bean paste balls wrapped in glutinous rice flour wrappers and coated with sesame seeds before being deep fried to perfection. It's crispy, chewy, and so addicting. A must-try!
Soak the mung beans. Start by soaking the yellow mung beans in water for 4-6 hours. This will allow them to soften and shorten the cooking time.
Cook them. After soaking, drain and rinse the beans a couple of times. Transfer them to a medium saucepan and cover with water. Bring to a simmer and cook uncovered for 12-15 minutes or until the mung beans are soft. Keep cooking until no more water remains and the beans start turning into a purée.
Process the paste. Transfer the cooked beans to a food processor or small blender. Add the sugar, shredded coconut, oil, vanilla extract, and salt. Process the mung bean paste for 20-30 seconds or until smooth. Be aware that the paste will be very thick and sticky. It’s normal.
Dehydrate. Transfer the mung bean paste to a large saucepan and heat over low-medium heat. Keep stirring the paste using a spatula for 3-5 minutes or until smooth. The paste should still be soft but not sticky anymore.
Let it cool. Transfer the mung bean paste to a bowl and cover it with plastic wrap, touching the top, to prevent the paste from forming a crust. Let it cool for at least 1 hour.
Shape into balls. Once the paste is not hot anymore, scoop out balls of about 1 and 1/2 tablespoons. I recommend using a medium cookie scoop to speed up the process. Use your hands to shape them into round balls. Transfer to a plate and cover with plastic wrap.
Chill. Finally, let the mung bean paste balls chill for at least 6 hours or overnight in the refrigerator.
Dough
Combine the dry ingredients. Add the glutinous rice flour, sugar, rice flour, baking powder, and salt to a mixing bowl. Whisk to combine.
Add the water and knead. Add the water and oil and knead using your hands until it forms a slightly firm dough. The dough should hold together when you press it between your fingers. Let the dough rest covered for 30 minutes (this will allow the flour to absorb the moisture).
Assemble
Flatten a ball of dough. Scoop out 1.5 tablespoons of the rice flour dough and roll it into a ball. Next, use your hands to shape it into a 2.5-inch (6cm) circle. Slightly press the edges to make them a bit thinner than the center.Place a ball of mung bean paste on top. Take a mung bean paste ball and place it in the center of the wrapper.
Wrap it tightly with the wrapper. Carefully wrap the wrapper tightly around the mung bean paste ball, trying not to let any air hole inside. Press to seal.
Roll it between your hands. Roll the ball between the palms of your hands. This will help the wrapper to get an even thickness.
Dip in sesame seeds. Transfer the raw sesame seeds to a small bowl. Dip the ball into the sesame seeds and toss to coat. Slightly press the sesame seeds onto the ball to make them stick. Transfer the sesame-coated ball to a plate.Repeat with the remaining filling. Repeat with the remaining mung bean balls and dough. You should end up with about 12 balls.
Fry
Heat the oil. Heat 3 cups of frying oil in a deep saucepan. Let the oil heat for at least 5 minutes. You can test if the oil is hot enough by dipping a wooden chopsticks into it. If you see a lot of small bubbles forming around the chopstick, the oil is hot enough.
Fry the sesame balls. Carefully transfer 4-5 balls to the oil and stir using a wooden spoon or chopsticks to prevent them from sticking to the bottom of the pan. Keep frying, stirring constantly, until the balls are golden brown. This step will take 5-7 minutes, so be patient.
Transfer to kitchen paper towels. Using a slotted spoon, remove the banh cam from the oil and transfer them to a plate lined with kitchen paper towels to remove excess oil.
Enjoy! Let the banh cam cool for at least 25 minutes before enjoying it!
Notes
Do not make the shell too thick. Using more dough to wrap the mung bean balls can be tempting. However, I do not recommend using more than 1.5 tablespoons. Otherwise, you will end up with a shell that is hard to chew. A thin and crispy shell tastes best here.
Slightly press the sesame seeds on the dough. To prevent the sesame seeds from falling during frying, ensure you are slightly pressing them onto the dough.
Ensure the oil is hot enough. If your frying oil is not hot enough, the balls will stick to the bottom of the pan, and you will end up with a mess. The oil should be between 365F and 380F (185°C and 193°C). If you don't have a thermometer, dip a wooden spatula or chopsticks into the hot oil. If tiny bubbles form around it, the oil is hot enough. If no bubbles form, keep heating the oil.
Be patient when frying. These sesame balls can take up to 7-8 minutes before puffing and turning golden brown, so be patient and do not try to turn the heat up.
Keep stirring. In order to achieve an even golden brown color, continuously stir using a spatula or chopsticks during the whole frying time.
Enjoy on the same day. Just like any fried food, Bánh cam tastes best the same day. After that, the dough will soften and become a bit more chewy.
