Preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper or silicone baking mats.

Toast Pecans (Optional but Recommended): Spread the chopped pecans on a dry baking sheet and toast them in the preheated oven for 5 to 7 minutes, or until fragrant. Allow them to cool completely before using them in the dough.

Cream Butter and Sugar: In the bowl of a stand mixer fitted with the paddle attachment (or using a hand mixer), beat the softened butter and the 1/2 cup of powdered sugar until the mixture is light and fluffy, about 2 to 3 minutes, scraping down the sides of the bowl as needed.

Add Flavoring: Mix in the vanilla extract and salt until just combined.

Add Flour and Pecans: Gradually add the 2 cups of all-purpose flour, mixing on low speed until the dough just comes together. Be careful not to overmix. Once the dough forms, stir in the cooled chopped pecans by hand until they are evenly distributed. The dough will be stiff and slightly crumbly.

Shape the Cookies: Use a small cookie scoop (about 1 tablespoon) or simply roll the dough into small, uniform balls, approximately 1 inch in diameter. Place the dough balls 1 to 2 inches apart on the prepared baking sheets.

Bake: Bake for 12 to 15 minutes, or until the cookies are set and the bottoms are lightly golden. The cookies should still look pale white on top. Remove from the oven and let them cool on the baking sheet for just 2 to 3 minutes.

First Roll (While Warm): Pour 1 cup of the reserved powdered sugar into a shallow dish. While the cookies are still warm (but cool enough to handle), gently roll each cookie in the powdered sugar until fully coated. Return the coated cookies to a wire cooling rack.

Cool Completely: Allow the cookies to cool completely on the wire rack (about 30 minutes).

Second Roll (When Cool): Pour the remaining 1/2 cup of fresh powdered sugar into the shallow dish. Once the cookies are entirely cool, roll them a second time in the fresh powdered sugar. This ensures the distinct, thick “snowball” look and prevents the sugar from absorbing moisture.

Serve and Store: Pecan Snowball Cookies can be stored in an airtight container at room temperature for up to one week.
