01 - Preheat oven to 350°F. Line two baking sheets with parchment paper and set aside.
02 - In a medium bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt until evenly distributed. Set aside.
03 - In a large mixing bowl, beat the softened vegan butter, granulated sugar, and brown sugar using an electric mixer on medium speed until the mixture is light and fluffy, about 2 to 3 minutes.
04 - Add the unsweetened applesauce, drained crushed pineapple, orange juice, orange zest, and vanilla extract to the creamed butter mixture. Beat on medium speed until fully combined.
05 - Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed just until the dough comes together. Avoid overmixing to keep the cookies tender.
06 - Drop rounded tablespoons of dough onto the prepared baking sheets, spacing each portion about 2 inches apart to allow for spreading.
07 - Bake for 10 to 12 minutes, or until the edges are lightly golden and the centers appear set. Let the cookies rest on the baking sheets for 5 minutes, then transfer to a wire cooling rack to cool completely.
08 - In a medium bowl, beat the softened vegan butter until creamy and smooth. Add the powdered sugar, drained crushed pineapple, orange juice, orange zest, and a pinch of salt. Beat on medium-high speed until the frosting is light and fluffy.
09 - Once the cookies have cooled completely, spread or pipe the pineapple orange cream frosting onto each cookie. Garnish with additional orange zest or small pieces of crushed pineapple if desired.
