Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
In a large mixing bowl, cream together the softened butter, cream cheese, granulated sugar, and brown sugar until smooth and fluffy.
Add the egg and vanilla extract to the creamed mixture, beating until well combined.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Gently fold in the diced strawberries, being careful not to overmix.
Drop rounded tablespoons of dough onto the prepared baking sheet, spacing them about 2 inches apart.
Bake in the preheated oven for 12-15 minutes or until the edges are lightly golden.
Remove from the oven and let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack.
Once cooled, dust with powdered sugar for an extra touch of sweetness and presentation.
