Lemon Thins Cookies


  • 1/4 cup fresh lemon juice
  • 3/4 cup unsalted butter cut into several pieces
  • 2 1/2 cups all-purpose flour
  • 1/4 teaspoon baking soda
  • 1 large egg
  • 1 large egg yolk
  • 1 cup sugar
  • 1 teaspoon lemon extract
  • 1/4 teaspoon salt
  • White sparkling sugar


  • In a small ceramic pot, bring the lemon juice to a boil, whisking while it heats. Let it boil for about 5 minutes, until it reduces to about a tablespoon.
  • Turn down the heat to medium low and add the butter, a few pieces at a time. Whisking until the butter has melted.
  • Remove from the heat and set aside.
  • Sift the flour, add the baking soda and salt, and set aside.
  • Place the egg and egg yolk in a large bowl, and using a hand mixer, beat until the egg has combined.
  • Add the sugar and beat until the mixture is creamy and pale.
  • While beating on low, drizzle in the melted butter mixture, until everything is blended.
  • Add half of the flour mixture until everything is blended, add the other half and mix only until everything is blended.
  • Cover the bowl with saran wrap and set in the fridge for an hour.
  • Cut the dough into 4 equal portions.
  • Place a portion on a piece of parchment paper, press flat with your hand. Place another piece of parchment paper on top and roll out to 1/8" thick. Slip the parchment onto a cookie sheet and repeat with each portion, stacking each piece on top of each other.
  • Place the cookie sheet into the fridge for 30 minutes.
  • Line an insulated baking sheet with a silpat pad and preheat the oven to 400°F.
  • Cut with a 2 1/2" cookie cutter, remove from the parchment paper, sprinkle with the sparkling sugar and place on the silpat pad about an inch apart.
  • Bake the cookies for 6 minutes to start, baking for an additional 30 seconds at a time, until the cookies are baked, but NOT brown.
  • Remove from the oven and let cool for about 5 minutes on the tray then move to a cooling rack.


Optional: Add the zest of 3 lemons, finely chopped.
I rotated a couple insulated pans, rolling out excess, and putting it into the fridge.
