Let Ingredients Come to Room Temperature. The butter, ricotta cheese, and egg must be at room temperature in order to cream together smoothly.
To avoid making a floury mess, add half of the flour mixture in at a time, and mix on low. If using a hand mixer, do this at the lowest speed possible (make sure that your mixer has this option!).
The cookies must be cooled completely before adding the glaze, if you don’t wait the glaze might melt.
It’s important that your cookies are uniform in size, this will make sure that they bake evenly.
If you want to make the cookies very round, roll them very quickly between your palms. The dough will be very soft to work with, so you will need to use a cookie scoop to quickly portion out the dough.
