Preheat your oven to 375°F (190°C) and grease a standard 12-cup muffin pan.

In a mixing bowl, combine granulated sugar with ground cinnamon.

Unroll the Pillsbury™ Original Crescent Dough, pressing it flat into a rectangle of about 13x8 inches. Spread softened butter evenly over the dough.

Sprinkle the cinnamon-sugar mixture over the buttered dough and press lightly.

Roll the dough tightly from one end and seal the seam. Cut the log in half, then slice each half into thirds, yielding 12 segments.

Shape each segment into a spiral and place into the greased muffin cups.

Bake the cruffins for about 18 minutes until golden brown.

Remove from oven, roll in leftover cinnamon-sugar mixture while warm, and cool slightly on a wire rack.
