Traditional five kernel moon cakes packed with nuts and seeds offer a crunchy, nutty filling. A classic family Mid-Autumn Festival dessert with heritage flavor.
Toast all nuts and seeds in a skillet over medium heat for 5–7 minutes, stirring constantly to avoid burning; set aside to cool.
Finely chop the nuts, seeds, and candied winter melon. Combine them in a large bowl.
Add granulated sugar, malt syrup, soy sauce, and salt. Mix to evenly coat the chopped mixture; knead until slightly sticky.
In a separate bowl, mix all-purpose flour, one egg, vegetable oil, and about 0.25 cup malt syrup to form a smooth dough. Let rest, covered, for 30 minutes.
Divide the rested dough and filling into 8 portions each. Flatten a dough piece, wrap a portion of filling, and seal; shape gently using a moon cake mold for definition.
Preheat oven to 350°F (175°C). Arrange moon cakes on a lined baking sheet. Brush with beaten egg for shine.
Bake for 20 minutes, reduce heat to 320°F (160°C), and bake 10–15 minutes more until golden brown. Cool thoroughly before serving for best texture.
