2 cups flour
1 cup unsalted butter
1/2 cup granulated sugar
2 tblsp coarse, or sparkling, sugar
1/4 tsp salt
optional: icing as desired
Preheat oven to 325°.
Add flour, butter, granulated sugar, and salt into a bowl and blend with a mixer on low speed until blended. Increase to medium and mix until dough is no longer crumbly and just comes together.
Use cookie molds or press dough evenly into a pan and sprinkle with coarse sugar.
Bake until golden brown, about 30-40 minutes.
In the pan, cut still-warm shortbread into wedges or slices. Let cool, then flip and separate.
