Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.
In a bowl, whisk together the flour, baking soda, baking powder, and salt; set aside.
In a large mixing bowl, beat together the softened butter and granulated sugar until light and fluffy (about 3-4 minutes).
Add the egg, vanilla extract, lemon zest, and lemon juice to the butter mixture, and continue to beat until well combined.
Gradually add the dry ingredients to the wet mixture, mixing until just incorporated.
Gently fold in the slightly mashed raspberries, being careful not to overmix to preserve the berry pieces.
Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheets, leaving enough space between each cookie to allow for spreading.
Bake for 10-12 minutes or until the edges are lightly golden. The cookies may look a bit soft in the middle; that's okay, as they will firm up as they cool.
Allow the cookies to cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely.
Once cooled, dust the cookies with powdered sugar before serving for an extra touch of sweetness.
