Crispy egg roll cookies with a thin, buttery, golden shell are a festive Chinese treat. A family recipe with fresh, sweet egg flavor and delicate crunch.
Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
Melt the butter over low heat until just liquefied, then allow to cool slightly.
In a mixing bowl, beat the eggs and sugar together for 2-3 minutes until pale and creamy; stir in vanilla extract and salt.
Gently fold melted butter into the egg mixture, then sift in flour. Mix until a smooth, thin batter forms—do not overmix.
Drop batter by tablespoon onto the baking sheet, spreading into thin circles about 4 inches across.
Bake for 7–8 minutes on the middle rack until edges are golden; work in batches if necessary to prevent overbaking.
Immediately, while hot, use a spatula to roll each cookie into a cylinder or cone shape. Let cool on a rack for crunch.
