Creating these Strawberry Cookies is simple when you follow these easy steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
2. Make Strawberry Puree: In a blender, puree the fresh strawberries until smooth.
3. Mix Wet Ingredients: In a large bowl, cream the softened butter and granulated sugar until light and fluffy. Then, add in the egg, strawberry puree, and vanilla extract, mixing well.
4. Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking soda, baking powder, and salt.
5. Combine Mixtures: Gradually add the dry ingredients to the wet mixture until just combined, being careful not to overmix.
6. Add Chocolate Chips: If using, fold in the white chocolate chips for added sweetness.
7. Scoop the Dough: Using a cookie scoop, drop dough balls onto the prepared baking sheet, spacing them about 2 inches apart.
8. Bake the Cookies: Bake for 12-15 minutes, until the edges are golden and the centers are set.
9. Cool the Cookies: Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
10. Dust with Powdered Sugar: For a lovely finishing touch, dust the cooled cookies with powdered sugar before serving.
