Preheat the oven to 350°F (175°C).

In a mixing bowl, combine flour, granulated sugar, powdered sugar, baking powder, and salt.

Add softened butter, egg, vanilla extract, and lemon juice to the dry ingredients, and mix until well combined.

Gently fold in the raspberries.

Drop spoonfuls of the dough onto a baking sheet lined with parchment paper.

Bake for 10-12 minutes or until the edges are lightly golden.

Allow cookies to cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
