These sweet maple cookies feature crisp edges, a chewy center, and a delicious maple frosting. Sprinkle them with sparkling sugar for an extra-pretty finish!
In a medium bowl, whisk together the flour, baking powder, cinnamon and salt. Set aside.
Beat sugar and butter together in a large bowl with an electric mixer or in the bowl of a stand mixer fitted with the paddle attachment until light and fluffy, about 3 minutes. Add maple syrup, egg yolks, and vanilla; beat at medium speed until smooth. Gradually beat in flour mixture at low speed until just combined.
Cover dough and chill in the refrigerator for at least 1 hour.
Preheat the oven to 325°F. Line baking sheets with parchment paper or silicone baking mats. Set aside.
Use a medium cookie scoop to portion the dough 2 inches apart onto the prepared baking sheets.
Bake in the preheated oven until the edges are barely golden and the centers are set, 17-19 minutes. Cool on the baking sheet briefly before removing to a wire rack to cool completely.
Once the cookies have cooled completely, prepare the frosting.
Add the butter, powdered sugar, maple syrup, vanilla, maple extract, salt, and half of the milk to the bowl of a stand mixer fitted with the paddle attachment or in a large bowl with an electric mixer. Beat on low speed until combined, then increase speed to high and mix for 2-3 minutes. If needed, add the remaining milk to reach your desired consistency.
Spread frosting onto cookies. If desired, sprinkle with sparkling coarse sugar immediately.
When measuring powdered sugar, use the same fluff, scoop, and level method that you use for measuring flour.
