Prepare the Cream Cheese Filling: Begin by mixing cold cream cheese, granulated white sugar, and vanilla until smooth and creamy.
Macerate Strawberries: In a bowl, combine finely diced strawberries with a small amount of sugar to draw out their juices.
Make Cookie Dough: In another bowl, beat softened butter with granulated sugar until light and fluffy. Add in egg and vanilla, then mix until well combined before gradually incorporating flour, baking powder, baking soda, and salt to form a cohesive dough.
Assemble Cookies: Shape cookie dough into balls, make an indentation in each ball, and fill it with prepared cream cheese filling followed by a spoonful of macerated strawberries before sealing it back up.
Roll and Bake Cookies: Roll each filled cookie ball in granulated sugar before placing them on a baking sheet lined with parchment paper. Bake until lightly golden around the edges; let cool slightly before enjoying these delectable treats!
