01 - Preheat the oven to 350°F. Line two baking sheets with parchment paper.
02 - In a large bowl, cream together the vegan butter and 3/4 cup sugar until light and fluffy. Add the applesauce, pineapple juice, and vanilla extract; mix until combined.
03 - In a separate bowl, whisk together the flour, baking soda, baking powder, and salt.
04 - Gradually add the dry ingredients to the wet mixture, stirring until just combined.
05 - Fold in the diced pineapple and chopped mint gently.
06 - Scoop tablespoon-sized balls of dough onto the prepared baking sheets, spacing them about 2 inches apart. Flatten each cookie slightly with your fingers or a spoon.
07 - Sprinkle the tops with additional sugar if desired.
08 - Bake for 10-12 minutes, or until the edges are lightly golden.
09 - Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
