1-First Step: Warm the milk to 110°F in a small bowl. Stir in yeast and 1 tsp sugar. Let sit 5-10 minutes until foamy. This proves yeast is active.

2-Second Step: In a large bowl, mix flour, remaining sugar, and salt. Cut in softened butter with a fork until crumbly. Add yeast mixture and beaten egg. Stir until a soft dough forms.

3-Third Step: Turn dough onto a floured surface. Knead 5-7 minutes until smooth and elastic. Place in a greased bowl, cover with a damp cloth, and let rise in a warm spot for 1 hour or until doubled.

4-Fourth Step: Punch down dough and divide into 4 equal balls (about 8 oz each). Roll one ball into a 10-inch circle on floured parchment. Place on a baking sheet.

5-Fifth Step: Spread 1/3 of cinnamon sugar (or 1/3 cup Nutella) evenly over circle, leaving 1-inch border. Roll second ball into circle, place on top, and repeat filling. Add third circle with filling.

6-Sixth Step: Top with fourth circle, no filling. Place a 2-inch round cutter (or glass) in center to mark. Use a knife to cut from center edge to outer edge into 16 equal strips.

7-Seventh Step: Remove cutter. Grab two adjacent strips, twist outward twice, then press ends down. Repeat around the circle for full star effect. Cover loosely and let rise 20-30 minutes.

8-Final Step: Preheat oven to 375°F. Brush with beaten egg for shine. Bake 20-25 minutes until golden. Cool 10 minutes on sheet, then transfer to rack. Dust with powdered sugar. Pull apart to serve warm. Total time: 2.5 hours.
