I prefer salted – but it is really a personal choice. You can you whichever one you like.

The mixture should be crumbly but form together when pressed into the pan. Does it stick together? If not, this could be the result of how the confectioner’s sugar and flour were measured. Did you scoop it or spoon into the measuring cup & then level off? Because those ingredients are so light and airy, they can easily be over scooped. To counter this try beating in additional butter, 1 tablespoon at a time until the mixture can stick together. Keep in mind this dough will not be the same consistency as a regular cookie dough. It will be dry and look like wet sand but will hold shape when pressed into the pan.

Hi Jan. Thanks for letting me know. Yes, there is a typo. It should be 4 sticks (2 cups) of butter with the 4 cups of flour (+ the 1 cup of confectioners sugar) OR 2 sticks of butter with 2 cups flour & 1/2 cup confectioners sugar. I have updated the recipe.

Obviously a typo
