02 - 2 tablespoons granulated sugar
03 - 1 teaspoon salt
04 - 2 1/4 teaspoons instant yeast
05 - 1/2 cup whole milk, lukewarm
06 - 1 large egg
07 - 2/3 cup unsalted butter, cold (for lamination)
08 - 2 tablespoons unsalted butter, melted (for dough)
→ Cookie Layer
09 - 5 tablespoons unsalted butter, softened
10 - 1/4 cup brown sugar
11 - 3 tablespoons granulated sugar
12 - 1 large egg yolk
13 - 1 teaspoon vanilla extract

# Step-by-Step:
01 - Combine flour, sugar, salt, and yeast in a bowl. Add lukewarm milk, melted butter, and egg, mixing until a soft dough forms. Knead for 5 minutes until smooth. Shape into a rectangle, cover, and chill for 30 minutes. Roll cold butter between parchment paper into a 6x6 inch square and refrigerate. Roll dough to a 12x6 inch rectangle, place butter in the center, fold dough over it from both sides, and seal.
02 - Roll dough out to 18x8 inch rectangle. Fold into thirds, then chill for 30 minutes. Repeat rolling and folding two more times with 30-minute chilling intervals. Refrigerate final dough for 1 hour.
03 - Beat softened butter with both sugars until creamy. Add egg yolk and vanilla extract; mix well. Incorporate flour, baking soda, and salt until just combined. Gently fold in chocolate chips. Cover and refrigerate while dough rests.
04 - Roll laminated dough into a 12x10 inch sheet about 1/4 inch thick. Spread cookie dough evenly atop, leaving a 1/3 inch border. Roll tightly along the long side and slice into 8 equal rounds. Arrange on parchment-lined baking sheet, cover lightly, and proof at room temperature for 1 hour.
05 - Preheat oven to 375°F. Bake crookies for 18 to 20 minutes until golden brown and cooked through. Transfer to a wire rack to cool completely before serving.
