For this cookie, we will need quite a lot of ingredients. Powdered sugar can be taken any, i.e. without vanilla. Instead of almonds, it's better to take almonds, but I couldn't buy and just bought nuts. You can take any oatmeal. For myself, I always use coarse flakes, and for cookies I took Hercules. In a blender, whisk the flakes with powdered sugar. I did not break it in order to sprinkle it with flour, but so that it was clear that it was grits.
