# What You'll Need:
→ Cookie Dough
01 - 1 cup unsalted butter, softened
02 - 2/3 cup granulated sugar
03 - 1 large egg yolk
04 - 1 teaspoon vanilla extract
05 - 2 1/4 cups all-purpose flour
06 - 1/4 teaspoon salt
→ Strawberry Jam Filling
07 - 3/4 cup fresh strawberries, hulled and diced
08 - 1/3 cup granulated sugar
09 - 2 teaspoons lemon juice
# How To Make It:
01 - Preheat oven to 350°F. Line two baking sheets with parchment paper.
02 - In a small saucepan, combine diced strawberries, sugar, and lemon juice. Cook over medium heat, stirring frequently, until strawberries break down and mixture thickens, approximately 8 to 10 minutes. Remove from heat and let cool completely.
03 - In a large bowl, cream together softened butter and sugar until light and fluffy. Add egg yolk and vanilla extract, beating until combined.
04 - Gradually add flour and salt, mixing until a soft dough forms.
05 - Scoop tablespoon-sized portions of dough and roll into balls. Arrange on prepared baking sheets, spacing 2 inches apart.
06 - Use your thumb or the back of a teaspoon to make an indentation in the center of each ball.
07 - Fill each indentation with approximately 1/2 teaspoon of cooled strawberry jam.
08 - Bake for 13 to 15 minutes, or until edges are just turning golden.
09 - Cool on baking sheets for 5 minutes, then transfer to a wire rack to cool completely.
