Combine butter, cream cheese, flour, and salt, kneading until smooth dough forms.

Divide dough into three balls. Cover in plastic wrap until chilled.

Preheat oven to 350 degrees Fahrenheit.

In a small bowl, combine nuts, sugar, cinnamon, and raisins (if desired).

Place dough on a floured surface and roll to 1/4-inch thickness into a nine-inch circle. Sprinkle sugar filling on dough, leaving 1/2-inch uncovered in the center. Cut into 16 triangles, using a pizza wheel or knife. Roll each triangle, starting from the wider edge, and place, seam-side down, on a lightly greased baking sheet.

Bake for 22 minutes or until light golden brown.
