Ingredients:

  • 4 cups all-purpose flour (500g)
  • 1/2 cup whole milk, warmed to about 110°F (125ml)
  • 1/2 cup water, warmed to about 110°F (125ml)
  • 1/4 cup granulated sugar (50g)
  • 2 teaspoons active dry yeast
  • 1 teaspoon salt
  • 3 tablespoons unsalted butter, melted and cooled (45g)
  • 1 cup unsalted butter, cold and cut into slices (225g)
  • 1 large egg
  • (Optional: a splash of milk or cream)

Instructions:

  1. In a small bowl, combine warm milk, warm water, and sugar. Sprinkle yeast over the top and let it sit for about 5 minutes until frothy.
  2. In a large mixing bowl or stand mixer with a dough hook attachment, combine flour and salt. Make a well in the center.
  3. Pour in the yeast mixture and melted butter into the well. Mix on low speed until combined.
  4. Knead for 8–10 minutes, either by hand on a floured surface or using your stand mixer at medium speed until you have a smooth dough.
  5. Form into a ball and place it in an oiled bowl; cover with plastic wrap or a kitchen towel. Allow it to rise in a warm place for about an hour, until doubled in size.
  6. While dough is rising, lay out parchment paper on your work surface and arrange sliced cold butter into an even rectangle roughly 7x9 inches.
  7. Place another piece of parchment paper over it and use a rolling pin to gently pound it down to flatten slightly before rolling out into that rectangle shape if needed.
  8. Refrigerate while waiting for your dough.
  9. Once risen, turn out onto lightly floured surface; roll into approximately 15x10 inches rectangle.
  10. Center your chilled butter block on one half of this rolled-out dough; fold other half over so that edges meet perfectly encasing butter inside.
  11. Pinch edges together securely to seal.
  12. Roll out again into long rectangle (24x10 inches) making sure not to tear through any areas where butter is visible.
  13. Wrap tightly in plastic wrap; refrigerate for at least 30 minutes before repeating steps of rolling/folding two more times; total turns should be three.
