Frosted Carrot Cake Cookies

Preheat the oven to 350 degrees F (175 degrees C). Grease 2 baking sheets.

Whisk flour, cinnamon, baking soda, and salt together in a bowl.

Beat butter, white sugar, and brown sugar together in another bowl until creamy. Add egg and vanilla extract; continue mixing until pale and fluffy, about 2 minutes. Mix in carrots, raisins, walnuts, and pineapple at low speed. Add flour mixture; beat until just combined.

Drop 1 1/2 tablespoons of batter at a time onto the prepared baking sheets, 2 inches apart.

Bake in the preheated oven until lightly browned and springy to the touch, 12 to 16 minutes. Remove from the oven and let cool on the sheets for 5 minutes before transferring to wire racks to cool completely, about 30 minutes more.

Blend cream cheese and honey together in a food processor or with an electric mixer until smooth. Sandwich flat sides of cooled cookies together with a generous tablespoon of cream cheese filling in between.
