01 - Preheat the oven to 350°F. Line two baking sheets with parchment paper.
02 - In a large bowl, cream together the softened butter and granulated sugar until light and fluffy, about 2–3 minutes.
03 - Beat in the egg, lemon juice, lemon zest, and vanilla extract until well combined.
04 - In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
05 - Gradually add the dry ingredients to the wet mixture, mixing until just combined; do not overmix.
06 - Gently fold in the raspberries, trying to keep them as whole as possible.
07 - Scoop heaping tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart.
08 - Sprinkle with coarse sugar or dust lightly with powdered sugar before baking, if desired.
09 - Bake for 11–13 minutes, or until the edges are just turning golden. The centers should remain soft.
10 - Allow cookies to cool on the tray for 5 minutes, then transfer to a wire rack to cool completely.
