Make tender, buttery shortbread cookies using a gluten-free flour blend, brightened with fresh lemon zest and a subtle hint of savory thyme.

Ingredients

Scale
  • 1 cup unsalted butter, softened
  • 1/2 cup powdered sugar
  • 1 teaspoon pure vanilla extract
  • 1 tablespoon fresh lemon zest
  • 1 teaspoon fresh lemon juice
  • 1/2 teaspoon dried thyme, finely crushed
  • 1/4 teaspoon salt
  • 2 cups gluten-free all-purpose flour blend (with xanthan gum)
  • 1/4 cup almond flour

Instructions

  1. Preheat your oven to 325 degrees Fahrenheit. Line two baking sheets with parchment paper.
  2. In a large bowl, cream the softened butter and powdered sugar together until light and fluffy.
  3. Beat in the vanilla extract, lemon zest, lemon juice, crushed dried thyme, and salt until just combined.
  4. Gradually add the gluten-free flour blend and almond flour to the wet ingredients. Mix on low speed until a soft dough forms. Do not overmix.
  5. Shape the dough into a log about 1.5 inches in diameter, wrap it in plastic wrap, and chill for at least 30 minutes.
  6. Remove the dough from the refrigerator. Slice the chilled log into rounds about 1/4 inch thick. Place the rounds on the prepared baking sheets, leaving about 1 inch between them.
  7. Bake for 15 to 18 minutes, or until the edges are lightly golden brown. The centers should still look pale.
  8. Let the cookies cool on the baking sheet for 5 minutes before carefully transferring them to a wire rack to cool completely.

Notes

  • For a finer texture, use a gluten-free blend that contains rice flour and tapioca starch.
  • If you use fresh thyme leaves instead of dried, use 1 teaspoon of finely minced fresh leaves.
  • For a decorative finish, press the tops lightly with a fork before baking, or dust with extra powdered sugar after cooling.
