Preheat oven to 325 degrees F. Line baking sheets with silicone baking mats or parchment paper and set aside.

Sift flour and salt into a small bowl.

Into a second bowl combine butter and sugar with an electric mixer on medium for 3 minutes until mixture is creamy. Mix in egg yolk until combined. Reduce to low speed. Add flour mixture and mix until just combined. Fold in pecans.

Using a small cookie scoop, drop batter onto prepared baking sheets, spacing 3 inches apart. Press one cinnamon pecan onto the top of each mound. Bake in preheated oven until golden around the edges, about 12 to 15 minutes. Let cool 10 minutes on baking sheet before removing to cooling rack to cool completely. Store in an airtight container up to 3 days.
