1 cup warm water

1 Tbsp white sugar

1 tsp active dry yeast

2 + ½ cups bread flour, divided

1+1 Tbsps. melted butter, or more as needed

1 + 2 tsps salt

1 cup ice-cold unsalted butter, divided

Seasoned Sugar:

⅔ cup white sugar

1. Make dough: 
1. Combine water, sugar, and yeast in a large bowl. Let rest until foamy, about 5 minutes.
2. Add 2 cups flour, 1 Tbsp melted butter, and salt to yeast mixture. Stir with a wooden spoon until a very wet sticky dough forms.
3. Dust work surface with remaining ½ cup flour. Turn dough out onto the floured surface. Knead, folding in excess flour as needed, until dough is soft, slightly sticky, and elastic. Place into a greased bowl, cover, and let rise in a warm place until doubled in volume, about 1½ hours.
2. Make seasoned sugar: 
1. Mix together sugar and most of the remaining salt in a bowl. Taste and add remaining salt if desired.
3. Grease a 12-cup muffin tin with remaining 1 Tbsp melted butter. Spoon some of the seasoned sugar into each cup and shake to coat. Turn tin over and return excess sugar to the bowl. Set the muffin tin aside until needed.
4. Transfer dough onto a floured surface and press into a rough rectangle. Roll dough into a rectangle about ⅛" to ¼" thick. Grate 1 stick ice-cold butter over dough, leaving a 1" border. Flatten butter using lightly floured hands. Fold rectangle widthwise into thirds. Press gently to square out the edges, then place onto a silicone-lined baking sheet. Wrap in plastic and refrigerate for 30 minutes.
5. Roll dough into a large rectangle again, pulling and stretching the corners as needed. Grate remaining stick ice-cold butter over the surface. Pat down with floured fingers and fold into thirds. Roll back out into a rectangle and fold into thirds. Repeat rolling and folding one more time. Wrap in plastic and refrigerate for at least 1 hour.
6. Preheat the oven to 375 degrees F (190 degrees C).
7. Sprinkle a generous amount of seasoned sugar onto your work surface. Place dough onto sugar and sprinkle more sugar on top. Roll into a large rectangle about 1/8- to 1/4-inch thick, turning and topping with sugar between rolls.
8. Use a pizza cutter to trim away uneven edges. Cut dough into 12 equal squares. Sprinkle more sugar on top. Lightly pinch each pastry into a crown shape by bringing all four corners to the center; place into the prepared muffin cups. Sprinkle more sugar on top. Let rest for 10 minutes.
9. Bake in the preheated oven until browned and puffed, 25 to 30 minutes. Transfer pastries to a cooling rack while still hot. Let cool for 15 minutes before serving.
