Crispy fried red bean paste cakes with sweet, smooth filling are a golden treat. A family dessert with naturally sweet, earthy red bean flavor.
In a bowl, combine the all-purpose flour, sugar, and salt. Gradually add water, mixing until a smooth, slightly sticky dough forms.
Divide the dough into 8 equal pieces. Flatten each piece into a 3-inch disc with your hands or a rolling pin.
Place a rounded teaspoon of red bean paste in the center of each disc. Carefully gather and pinch the edges to seal, shaping into a ball and pressing gently into a puck shape.
Heat vegetable oil in a skillet over medium heat to 340°F (medium-low), ensuring even temperature for gentle frying.
Fry cakes in batches for 2–3 minutes on each side, turning occasionally for even browning, until golden and crisp outside. Drain on paper towels before serving.
