Shimmer Cookies with Raspberry Filling

Step 1

Preheat the oven to 350°F. Line two baking sheets with parchment.

Step 2

, To make the dough: In a large bowl, beat together the butter, confectioners’ sugar, salt, and Fiori di Sicilia until smooth. Add the flour and mix just until combined.

Step 3

, Scoop teaspoon-sized balls of dough and roll them in sparkling sugar. Place the balls on the prepared baking sheets.

Step 4

, Bake for 12 to 14 minutes, just until the cookies begin to brown at their edges. Remove from the oven and let cool on the pan for 5 minutes before transferring to a rack to finish cooling completely.

Step 5

, To make the filling: Place the confectioners’ sugar and the freeze-dried raspberries in the bowl of a food processor. Process until the berries are powdered. Whisk the mixture through a mesh strainer to remove any lumps or seeds. Mix in the butter at low speed until everything is cohesive. Add the milk, a teaspoon at a time, until the filling's spreadable.

Step 6

, To assemble: Scoop a teaspoon of filling onto the bottom of half the cookies; sandwich with the remaining cookies, pressing gently.
