Mexican wedding cookies rolled in powdered sugar are a delicate, nutty confection. This family-favorite treat is a buttery, crumbly, melt-in-your-mouth cookie for celebrations.
Preheat the oven to 350°F (175°C) and line two baking sheets with parchment paper.
In a large bowl, cream the unsalted butter and 0.5 cup powdered sugar together with an electric mixer on medium speed until light and fluffy, about 2–3 minutes.
Blend in the vanilla extract and salt. Gradually add the all-purpose flour, mixing on low speed just until combined.
Fold in the finely chopped pecans by hand, ensuring even distribution without over-mixing.
Form the dough into 1-inch balls and place them 1 inch apart on prepared baking sheets.
Bake for 13–15 minutes, watching for the bottoms to turn light golden while the tops remain pale and cookies remain soft to the touch.
Allow cookies to cool for 5 minutes on the baking sheet, then gently roll each warm cookie in powdered sugar and transfer to a wire rack to cool completely.
Once cool, roll the cookies a second time in fresh powdered sugar for a snowy finish.
