01 - Preheat oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together flour, baking powder, baking soda, and salt until evenly blended.
03 - In a large mixing bowl, beat softened butter, granulated sugar, and brown sugar together until light and creamy, about 2-3 minutes.
04 - Add the egg and vanilla extract to the butter mixture. Beat until fully incorporated and smooth.
05 - Mix in the freeze-dried strawberry powder until well blended and color is uniform throughout the dough.
06 - Gradually add the dry ingredients to the wet mixture, mixing just until combined. Avoid overmixing to prevent tough cookies.
07 - Gently fold in white chocolate chips and chopped fresh strawberries until evenly distributed.
08 - Using a heaping tablespoon per cookie, drop dough onto prepared baking sheets, spacing 2 inches apart to allow for spreading.
09 - Gently press heart-shaped sprinkles on top of each cookie dough mound, if using.
10 - Bake for 11-13 minutes until edges are set and centers are puffed. Do not overbake to maintain soft texture.
11 - Cool on baking sheet for 5 minutes, then transfer to wire rack to cool completely before serving.
