Instructions

  1. Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
  2. In a large bowl, cream together softened unsalted butter and granulated sugar until light and fluffy.
  3. Add one large egg and one egg yolk, along with three tablespoons of fresh lemon juice; mix until well combined.
  4. In another bowl, whisk together flour, cornstarch, baking powder, baking soda, and salt. Gradually add to the wet mixture until combined.
  5. Chill the dough for at least 30 minutes before scooping tablespoon-sized portions onto prepared baking sheets, spaced about 2 inches apart.
  6. Bake for 10-12 minutes or until edges are slightly golden while centers remain soft. Let cool on the baking sheet for 5 minutes before transferring to wire racks.
  7. For frosting, beat softened butter and powdered sugar together; then mix in blueberry jam and milk until smooth. Frost cooled cookies generously.
