01 - Preheat the oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together the flour, baking soda, baking powder, and salt until well blended.
03 - In a large bowl, beat the softened butter and granulated sugar together until light and fluffy, approximately 2–3 minutes.
04 - Add the egg, lemon zest, lemon juice, and vanilla extract to the butter mixture. Beat until thoroughly incorporated.
05 - Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Avoid overmixing.
06 - Gently fold in the raspberries and white chocolate chips, taking care not to crush the berries.
07 - Scoop tablespoon-sized balls of dough onto the prepared baking sheets, spacing them 2 inches apart.
08 - Bake for 10–12 minutes, until the edges are lightly golden and the centers are set.
09 - Allow the cookies to rest on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
