01 - Preheat the 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 fine sea salt until evenly distributed.
03 - In a large mixing bowl, beat the softened vegan butter and granulated sugar together using an electric mixer on medium speed until the mixture is light and fluffy, approximately 2 to 3 minutes.
04 - Add the unsweetened applesauce and vanilla extract to the butter-sugar mixture. Beat until fully incorporated and smooth.
05 - Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed until a soft, cohesive dough forms. Avoid overmixing.
06 - Scoop tablespoon-sized portions of dough and roll into balls. Place on the prepared baking sheets, spacing each about 2 inches apart. Gently flatten each dough ball with your fingers or the bottom of a glass.
07 - Bake for 8 to 10 minutes, or until the edges are just beginning to turn golden. Allow the cookies to rest on the baking sheets for 5 minutes, then transfer to a wire rack to cool completely.
08 - In a small bowl, lightly mash the raspberries with a fork. In a separate bowl, beat the vegan cream cheese, powdered sugar, and lemon juice together until smooth and creamy. Gently fold in the chopped pineapple and mashed raspberries until just combined.
09 - Once the cookies have cooled completely, spread a generous teaspoon of the pineapple raspberry cream onto the flat side of half the cookies. Top each with a second cookie, flat side down, to form sandwich cookies.
10 - Refrigerate the assembled cookie sandwiches for 30 minutes to allow the cream filling to set before serving.
