Preparation

Step 1

1. Preheat oven to 350 degrees. Line 2 baking sheets with parchment. Sift flour, baking powder, baking soda, and salt into a bowl. Combine banana and sour cream in another bowl.

2. Beat butter, sugar and brown sugar with a mixer on medium-high spee, until pale and creamy, about 3 minutes. Add egg and 1/2 tsp. vanilla, beating until incorporated. Add banana mixture in 2 additions, alternating with flour mixture.

3. Transfer batter to a pastry bag fitted with a 1/4" plain tip. Pipe batter into 1 1/4 inch rounds on baking sheets, spacing rounds 1 1/2 inches apart.

4. Bake until edges are golden, about 12 minutes. Slide parchment, with cookies, onto wire racks. Let cool. (Unfilled cookies can be stored for up to 1 day.)

5. Beat cream cheese, powdered sugar, and remaining 1/2 tsp. vanilla with a mixer on medium speed until smooth, about 2 minutes.

6. Pipe or spoon 1 Tb. cream cheese mixture onto the flat sides of half the cookies. Sandwich with remaining cookies. Dust with powdered sugar, and serve immediately.
