01 - Preheat the oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together flour, baking soda, and salt. Set aside.
03 - In a large bowl, cream softened butter and sugar together using a mixer until pale and fluffy, about 2-3 minutes.
04 - Beat in the egg, lemon zest, lemon juice, and vanilla extract until well combined.
05 - Gradually add the dry ingredients to the wet mixture, mixing until just combined.
06 - Gently fold in raspberries and white chocolate chips, being careful not to crush the berries too much.
07 - Using a cookie scoop or tablespoon, drop dough onto prepared baking sheets, spacing about 2 inches apart.
08 - Bake for 11-13 minutes, or until the edges are just golden and centers look set but still soft.
09 - Cool cookies on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
