1 and 1/2 cups all-purpose flour
1/2 cup unsweetened cocoa powder
1 teaspoon baking soda
1 teaspoon baking powder
1 teaspoon salt
1 cup (2 sticks) unsalted butter, room temperature
1 cup packed light-brown sugar
1 large egg
1 cup unsweetened applesauce
1 cup confectioners' sugar
Preheat oven to 375 degrees. In a medium bowl, whisk flour, cocoa, baking soda, baking powder, and salt; set aside.
In a large bowl, using an electric mixer, beat 1/2 cup butter and brown sugar until light and fluffy. Add egg; beat until smooth. With mixer on low, alternately add flour mixture and applesauce, beginning and ending with flour mixture. Mix just until smooth (do not overmix).
Drop dough by heaping tablespoons, 2 inches apart on a baking sheet. Bake until toothpick inserted at center of cookie comes out clean, 10 to 14 minutes. With a thin metal spatula, immediately transfer cookies to a wire rack; let cool completely.
Meanwhile, make filling: In a medium bowl, using an electric mixer, beat vanilla and remaining 1/2 cup butter until light and fluffy. Gradually add confectioners' sugar, beating until smooth.
Spread bottom half of cookies with 1 tablespoon filling each; sandwich with a cookie similar in size. Let rest 15 minutes to set.
