01 - Preheat 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 evenly distributed.
03 - In a large bowl, beat the softened vegan butter and granulated sugar together using an electric mixer until light and fluffy, about 2 to 3 minutes.
04 - Pour in the non-dairy milk and vanilla extract to the butter mixture, beating until fully combined and smooth.
05 - Gradually add the dry ingredient mixture to the wet ingredients, stirring gently just until the flour is incorporated. Do not overmix.
06 - Gently fold in the crushed freeze-dried raspberries. If using fresh raspberries, fold very carefully to avoid breaking them apart too much.
07 - Scoop tablespoon-sized portions of dough and roll each into a ball. Roll each ball in extra granulated sugar to coat evenly.
08 - Place the dough balls on the prepared baking sheets, spacing them about 2 inches apart to allow for spreading.
09 - Bake for 10 to 12 minutes, or until the edges are set and just beginning to turn golden brown.
10 - Let the cookies cool on the baking sheets for 5 minutes, then transfer to a wire rack to cool completely.
