Crisp Vanilla Wafer Cookies in 25 Min

Instructions:

1. Beat the softened butter with granulated sugar and powdered sugar until the mixture is pale, fluffy, and sweet.
2. Stir in the vanilla extract and milk. Beat on low speed until the liquid is fully emulsified and the batter looks glossy.
3. Sift in the all-purpose flour and salt. Mix on the lowest speed just until the white streaks of flour disappear to avoid overmixing.
4. Transfer the dough to a piping bag and pipe 1-inch rounds onto parchment-lined baking sheets, leaving 2 inches of space between each cookie.
5. Bake at 325°F (160°C) for 12–15 minutes, until the edges turn a light mahogany color while the centers remain pale.
6. Allow the wafers to sit on the hot pan for 5 minutes to set, then transfer them to a wire rack to cool completely.
