candied cherries or pecan halves for garnish, if desired
Preheat oven to 325°. In a mixer, cream butter and sugar, then gradually add flour. Add salt and vanilla.
Line a rimmed baking sheet with a Silpat or parchment paper. Using a rolling pin, gently roll out the dough to ¼-inch thick, in a rough rectangle. Using a sharp knife, cut into 1-inch-square pieces. Press cherry or pecan halves onto each square.
Bake at 325° for 20 minutes or until golden brown. Remove from oven and let cool. The cuts will have melded back together, but quick work with a sharp knife will take care of that. Store in an airtight container at room temperature.
