These eggnog latte cookies are made with typical cookie ingredients but a little bit healthier: olive oil (instead of butter), egg yolk, brown sugar, vanilla extract, eggnog, white whole wheat flour (instead of all-purpose flour to get some fiber), baking soda, espresso powder, ground cinnamon and nutmeg, and salt! And then the glaze is made of powdered sugar, eggnog, vanilla extract, espresso powder, and ground cinnamon.
