Preheat oven to 350°F. Line a baking sheet with baking parchment or a silicone baking mat.
Add your butter with sugar into a large bowl and beat with an electric whisk for a few minutes until combined and fluffy. If you’re using vanilla extract, add it as well.
Add in your flour and beat again until combined. The dough will be crumblier than typical cookie dough.
Break off/ scoop walnut sizes pieces and roll them in your hands.
Place the cookie balls onto the prepared tray and using a flat-bottomed glass press down to flatten to one-quarter to one-half inch thickness. You can press some sprinkles into the tops at this point.
Bake in your preheated oven for between 14 to 16 minutes, until the edges are just turning golden brown.
Cool on the baking sheet for about five minutes, then move to a rack to cool completely. Enjoy!
