Instructions
Cookies
In a large bowl using a hand-held mixer or stand mixer fitted with a paddle attachment, beat the butter and sugar on medium speed for 4-5 minutes or until light and fluffy. Beat in egg yolks and vanilla extract until combined. Scrape down the sides and bottom of the bowl as needed.
Sift the flour and cocoa powder together in a medium bowl and whisk in salt. On low speed, slowly add flour mixture to butter mixture. Do not over mix but make sure all the flour is incorporated.
Divide the dough into 2 equal parts. Add some powdered sugar to rolling pin and parchment paper. Roll each portion out onto a piece of parchment to ¼″ thickness. Chill in fridge for 1 hour.
Preheat oven to 350°F. Line 2 baking sheets with parchment paper. Remove dough from fridge and use a cookie cutter to cut in shapes. Transfer the cut cookie dough to the prepared baking sheet. Re-roll the remaining dough and continue cutting until all is used.
Bake for 10-12 minutes, rotating pan halfway through. You will know the cookies are done when the edges are firm but the middle is still a little soft. Allow to cool for 5 minutes on pan and then transfer to wire rack to cool completely.
Decorate the cookies however you'd like the with royal icing recipe below. The icing should be set in about 2 hours so you can stack them. The cookies should last about 5 days at room temperature.
Royal Icing
In a large bowl using a hand-held mixer or a stand mixer fitted with a whisk attachment, beat all of the icing ingredients together on high speed for 5 minutes until stiff peaks form. Always start with 3 tablespoon of water to be safe, but you'll probably need 4 for right consistency. If it's too thin, add more powdered sugar and if too thick, add more water. Once desired consistency beat in vanilla extract.
