Chewy and sticky sweet, these molasses cookies will be a surefire hit at your holiday cookie swap.
Heat oven to 375 degrees. Line 2 baking sheets with parchment paper; set aside. In an electric mixer, use the paddle attachment to combine butter and brown sugar; mix on high speed until fluffy, about 2 minutes.
Add egg and molasses, and mix on medium speed until combined, about 20 seconds, scraping down the sides of the bowl once.
In a medium bowl, whisk together flour, baking soda, and salt; add to butter mixture. Mix on low speed to combine, 20 seconds.
Using 2 spoons, drop 2 teaspoons of batter on a baking sheet; repeat, spacing them 3 inches apart. Bake for 5 minutes. Sprinkle tops of cookies with granulated sugar, rotate sheets between oven shelves, and bake 8 minutes more. Rotate sheets again and bake until cookies are just brown around the edges, about 6 minutes more. Slide parchment with cookies onto a wire rack; let cool for 15 minutes. Store in an airtight container.
