The Modern Nonna

0 Preheat the oven to 350F. In a bowl, mix the almond flour and sugar and set aside. In a separate bowl, whisk the egg-whites until they are white and foamy for about 1-2 minutes.
1 Now add in the almond extract (or Amaretto) and whisk for a few seconds. Add the egg-white mixture into your dry ingredients. Incorporate with a spatula or switch to using your hands if you have a hard time. 
6 If the dough sticks to your hands you can wet your hands a bit and roll. 
5 Incorporate everything until you have a nice sticky dough. Once you have a sticky dough you can roll each cookie into balls — take a measuring spoon or small ice-cream scoop and scoop the dough into your hands and roll them. 
2 Dip each cookie ball into powdered sugar and place them on your baking sheet lined with parchment paper. Flatten each cookie gently with your fingers or the back of a spoon.
3 You can also roll them into a ball and then roll into a thick short rope and make a half-moon shape and then dip it crushed almond slices, and then add powdered sugar on top. You can also make half-moons and leave them plain as well.
4 Bake at 350F for 20 minutes or until light golden bottoms. Let them cool and place them in a glass Tupperware as they will be delicious even 2-3 days before Christmas. Enjoy and share with your loved ones!
