Ingredients:
- 1 cup (225g) unsalted butter, softened
- 1 cup (200g) granulated sugar
- 1 large (50g) egg, room temperature
- 2 tsp (10ml) fresh lemon zest
- 2 tbsp (30ml) fresh lemon juice
- 1 tsp (5ml) vanilla extract
- 2 ¼ cups (280g) all-purpose flour
- 2 tsp (6g) cornstarch
- ½ tsp (3g) baking soda
- ¼ tsp (1.5g) salt
- 1 cup (120g) powdered sugar
- 2 tbsp (30ml) fresh lemon juice
- 1 drop (0.5ml) lemon extract
Instructions:
- Beat the softened butter and granulated sugar on medium-high speed until the mixture looks pale and fluffy (about 2-3 minutes).
- Incorporate the egg, lemon zest, lemon juice, and vanilla extract, beating until the emulsion is smooth and glossy.
- Whisk the flour, cornstarch, baking soda, and salt together in a separate bowl.
- Gradually add the dry mixture to the wet ingredients on low speed, mixing only until the white streaks of flour disappear.
- Scoop rounded tablespoons of dough (about 1.5 tbsp each) onto parchment-lined sheets, spacing them 2 inches apart.
- Bake at 350°F (175°C) for 8–10 minutes; remove when edges are barely set and tops remain pale.
- While cookies cool on a wire rack, whisk together powdered sugar, lemon juice, and lemon extract until a thick, drizzlable consistency forms.
- Drizzle the icing over the cooled cookies.
