One of the many reasons I love this time of year is because of the eggnog!!! I remember when we were little, eggnog was a special treat. We didn’t have it too much, but when we did I sure did savor every drink! My 5 year old little girl does not like eggnog but she sure ate all the cookies that I would let her!
In a large bowl, cream sugar and butter with an electric mixer. Add eggnog, vanilla and egg yolks and beat at medium speed until smooth.
In a medium bowl combine flour, baking powder, cinnamon and nutmeg; mix well with a wire whisk and add to your eggnog/sugar/butter mixture.
Stick in the refrigerator until dough is cool
Next drop by rounded teaspoons onto a greased baking sheets, 1 to 2 inches away from each other. Bake for 17 to 22 minutes or until bottoms turn light brown. - Be sure to keep an eye on them
Transfer to cool, flat surface immediately with spatula. - If you leave them on the pan they will burn!
In small mixer bowl, beat the powdered sugar and butter until well blended. Gradually beat in eggnog until icing is smooth and the desired consistency. You may need less or more egg nog depending on the consistency you like. Then frost the cookies and let the icing harden.
