Knead the mixture thoroughly until the dough reaches a soft and smooth consistency. Wrap the dough with plastic wrap and allow it to rise for 30 to 45 minutes.
Heat 2 tablespoons of oil, toss in the sliced shallots and stir vigorously over high heat. Once the shallot slices achieve a rich, dark yellow, turn off the heat. Transfer them to a plate lined with paper towels to soak up excess oil
In a large skillet, heat 1 tablespoons of oil over medium heat. Add the minced garlic and shallot, sauté for about 1-2 minutes, until fragrant.

Shape the cooled mixture into round balls, each about the size of a chicken egg.
Combine glutinous rice with 1 teaspoon of salt and soak for 15 minutes.
Divide the dough into equal portions and flatten them. Place the mung bean-meat ball in the in the center. Carefully fold the dough over the filling, pinching the edges to seal and form a smooth ball. Repeat until all the fillings and dough are used.
Roll each cake in a thin layer of glutinous rice.
In the steamer, layer glutinous rice on the bottom, add the sticky rice cakes one by one, and evenly cover with the remaining glutinous rice on top. Wrap the pot lid with a towel to prevent mushiness. Steam for approximately 45 minutes.
