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 evenly distributed.
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 and smooth.
05 - Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined. Avoid overmixing to prevent tough cookies.
06 - Gently fold in the fresh raspberries and white chocolate chips using a spatula, taking care to minimize crushing the berries.
07 - Scoop tablespoon-sized balls of dough onto the prepared baking sheets, leaving 2 inches of space between each cookie to allow for spreading.
08 - Bake for 10–12 minutes, or until edges are lightly golden and centers appear set.
09 - Let the cookies rest on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
