In a medium-size bowl, whisk together flour, baking soda, and salt. Set aside.
In a large bowl using an electric mixer, beat together butter and a cup of granulated sugar on medium speed until light and fluffy. Add lemon zest, lemon juice, lemon extract, and vanilla extract; mix until just combined.
Scrape down the sides of the bowl, add egg; mix until just combined.
Add flour mixture to wet ingredients; mix just until combined.
Cover cookie dough with plastic wrap and refrigerate for 2-4 hours, or overnight.
Preheat oven to 350F degrees.
Scoop chilled dough into tablespoon balls, or use a #40 disher to scoop balls of dough. Roll balls of dough into the remaining ¼ cup of granulated sugar. Place on an ungreased baking sheet or silicone baking mat/parchment paper lined baking sheet. Keep dough chilled in between batches.
Bake 12-14 minutes. Cookies may appear to be soft and undone, but they will set as they cool.
Cool cookies on a baking sheet on a wire rack for 5 minutes; transfer to a wire rack to cool completely. Eat & Enjoy!
