Preheat the oven to 350°F (175°C).
In a mixing bowl, whisk together the flour, baking powder, and salt.
In a separate large bowl, cream together the softened butter and granulated sugar until light and fluffy.
Beat in the egg and vanilla extract until well combined.
Add the strawberry puree to the wet ingredients, mixing well.
Gradually add the dry ingredients to the wet mixture, blending until just combined.
Using a cookie scoop or spoon, drop the dough onto a parchment-lined baking sheet, leaving space between each cookie.
Bake for 10-12 minutes or until the edges are lightly golden.
Allow the cookies to cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
Dust with powdered sugar before serving.
