Almond Poppy Seed Cookies with Almond Frosting

1. Preheat the oven to 350ºF, and prepare some sheet pans with Silpats or parchment paper.

6. Place the dough on the prepared sheet pans.
7. Bake the cookies for 8-10 minutes until still pale, but cooked through. Gently remove from the pan and set out to cool.
8. While the cookies are cooling, prepare the almond frosting.
9. In the bowl of a standing mixer, whip together the butter, powdered sugar, almond extract and milk and beat until fluffy.
