Add the powdered sugar to a medium bowl.

Melt the butter using the microwave or stovetop, then let it cool for about 5 minutes before mixing it with the sugar.

Whisk until smooth, then gradually incorporate the flour into the mixture.

Use a spatula to gently fold the flour, creating a soft dough.

Scoop slightly heaping teaspoons of dough and place them on a parchment-lined baking tray, forming small balls.

Take a fork and lightly press down on each ball to flatten to about 1 inch round.

If desired, chill the tray of dough balls in the refrigerator for about 15 minutes before baking.

Preheat the oven to 356°F and bake the cookies for 10 to 12 minutes until lightly golden.

Allow the cookies to cool completely before storing in an airtight container for up to 5 days.
