Divide the plain dough into two equal pieces. Divide the pink dough into two equal pieces. You now have four portions total.
Roll each portion into a 10-inch (25 cm) circle on a lightly floured surface.
Line a large baking sheet with parchment paper. Place one plain dough circle on the parchment.
Spread one-third of the cinnamon filling evenly over the dough, leaving the very center clear.
Place one pink dough circle on top. Spread another third of the filling.
Place the second plain dough circle on top. Spread the remaining filling.
Place the second pink dough circle on top. (The pink dough is in the center layers so the color alternates when twisted.)
Place a small glass or round cutter (about 2 inches) in the center of the stack to mark the center. Do not cut through.
Using a sharp knife or bench scraper, cut from the edge of the center circle to the outer edge, dividing the dough into 4 equal quarters. Then cut each quarter into 4 strips, giving you 16 strips total. Leave the center intact.
Take two adjacent strips and twist them away from each other twice. Pinch the ends together firmly to form a point. Repeat with all pairs to create 8 points.
Cover loosely with plastic wrap or a clean towel. Let rise 30-45 minutes while you preheat the oven to 350°F (180°C). The dough needs this time to relax after all that handling.
