Preheat your oven to 350°F (175°C).
In a large bowl, beat together the softened butter, cream cheese, and sugar until light and fluffy.
Add in the egg and vanilla extract, mixing until well combined.
In a separate bowl, whisk together the flour, baking powder, and salt.
Gradually add the dry mixture into the wet batter, mixing until just combined.
Fold in the chopped strawberries gently.
Drop tablespoon-sized portions of dough onto a lined baking sheet.
Bake for 12-15 minutes until the edges are lightly golden.
Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack.
