1. 1. Preheat your oven to 350°F. Line baking sheets with parchment paper.

2. 2. In a large bowl, cream together butter and sugar until light and fluffy. Stir in minced rosemary and salt. Gradually mix in flour until a dough forms.

3. 3. Roll out the dough on a lightly floured surface to about 1/4-inch thickness. Use a Christmas tree cookie cutter to cut shapes and place them on the prepared baking sheets.

4. 4. Bake the cookies for 10–12 minutes, or until the edges are lightly golden. Allow the cookies to cool completely on wire racks.

5. 5. In a large bowl, combine the confectioners’ sugar, meringue powder, and 10 tablespoon of water. Beat the mixture until it’s smooth. Divide and tint the icing with green and brown food coloring as desired.

6. 6. Pipe the colored icing onto the cooled cookies to resemble Christmas tree decorations. Sprinkle with colored sugar or attach large nonpareils as ornaments. Allow the icing to set before serving.
