01 - Preheat the oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together the flour, baking powder, baking soda, and salt until well blended.
03 - In a large bowl, beat the softened butter and 1 1/4 cups sugar with an electric mixer until light and fluffy, about 2-3 minutes.
04 - Add the egg, lemon zest, lemon juice, and vanilla extract to the butter mixture, beating until fully incorporated.
05 - Gradually add the dry ingredients to the wet ingredients, mixing on low speed just until the flour disappears. Do not overmix.
06 - Gently fold in the raspberries with a spatula, being careful not to crush them.
07 - Scoop tablespoon-sized portions of dough, roll gently into balls, and roll each ball in the remaining 2 tablespoons sugar to coat evenly.
08 - Place dough balls 2 inches apart on the prepared baking sheets to allow for spreading.
09 - Bake for 11-13 minutes, or until the edges are just starting to turn golden brown but centers remain soft.
10 - Let cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
