1. Preheat the oven to 350°F and line two baking sheets with parchment paper.

2. Beat the butter, cream cheese, and granulated sugar together until light and fluffy.

3. Mix in the egg and vanilla extract until smooth.

4. In a separate bowl, whisk together the flour, baking powder, and salt.

5. Add the dry ingredients to the wet ingredients and mix just until combined.

6. Fold in the strawberry preserves and crushed freeze-dried strawberries gently, leaving some swirls in the dough.

7. Chill the dough for 30 minutes.

8. Scoop the dough onto the prepared baking sheets, spacing the cookies about 2 inches apart.

9. Bake for 11 to 13 minutes, until the edges are set and the centers are still soft.

10. Let the cookies cool completely.

11. Stir the powdered sugar and milk together to make a simple glaze, then drizzle over the cooled cookies if desired.
