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 combined.
05 - Gradually incorporate the dry ingredients into the wet mixture, 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, leaving 2 inches of space between each cookie.
08 - Bake for 10-12 minutes until the edges are lightly golden and the centers appear set.
09 - Let the cookies rest on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
