Step 1: Make the Cookie Dough

1. Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
2. In a large bowl, cream together the butter and sugar using an electric mixer until light and fluffy, about 2-3 minutes.
3. Add the egg and vanilla extract, mixing until well combined.
4. In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until a soft dough forms.

Step 2: Shape and Bake the Cookies

5. Scoop tablespoons of dough, roll them into balls, and place them on the prepared baking sheets about 2 inches apart. Alternatively, roll out the dough on a lightly floured surface and cut into shapes.
6. Bake for 10-12 minutes or until the edges are just starting to turn golden. Remove from the oven and let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Step 3: Make the Strawberry Glaze

7. In a blender or food processor, puree the chopped strawberries until smooth.
8. In a small bowl, combine the strawberry puree, powdered sugar, vanilla extract, and 1 teaspoon of milk. Mix until smooth and pourable, adding more milk as needed to reach your desired consistency.

Step 4: Glaze the Cookies

9. Once the cookies are completely cool, dip the tops into the strawberry glaze or use a spoon to drizzle it over them. Allow the glaze to set for 15-20 minutes before serving.
