Ingredients

For the Dough:

4 cups all-purpose flour

1/2 cup warm milk

1/2 cup cold water

1/4 cup granulated sugar

2 teaspoons salt

1 tablespoon active dry yeast

1/4 cup unsalted butter, melted

1 large egg (for egg wash)

For the Butter Layer (Detrempe):

1 cup unsalted butter, cold and sliced

Instructions

1. Prepare the Yeast Dough

In a small bowl, activate the yeast by mixing it with warm milk and a pinch of sugar. Let sit for 5-10 minutes until frothy.

In a large mixing bowl, combine the flour, remaining sugar, and salt.

Add the activated yeast mixture, cold water, melted butter, and egg to the dry ingredients.

Mix until a shaggy dough forms, then knead on a floured surface for about 8-10 minutes until smooth and elastic.

Shape into a ball, wrap in plastic wrap, and refrigerate for at least 2 hours or overnight for better flavor development.

2. Prepare the Butter Block (Detrempe)

Place the sliced cold butter between two sheets of parchment paper.

Pound and roll the butter into an even square about 8x8 inches.

Chill in the fridge until firm but pliable.

3. Laminate the Dough

Roll out the chilled dough into a rectangle about 16x10 inches.

Place the butter square in the center of the dough.

Fold the dough over the butter like an envelope, sealing the edges.

Roll out the dough into a long rectangle, then fold into thirds (like a letter).

Wrap and chill for 30 minutes.

Repeat the rolling and folding process 2 more times, chilling between each fold to create layers.

4. Shape the Croissant de Lune

Roll out the laminated dough into a large rectangle (about ¼ inch thick).

Cut into triangles roughly 4 inches wide at the base.

Starting from the wide end, roll each triangle tightly towards the point, shaping into a crescent.

Curve the rolled dough into a moon shape, pressing the ends gently to secure.

5. Proof and Bake

Place the shaped croissants on a parchment-lined baking sheet.

Cover lightly with a clean towel and let rise in a warm place for 1-2 hours until puffy.

Preheat your oven to 375°F (190°C).

Brush the croissants gently with an egg wash (beaten egg with a splash of water) for a shiny finish.

Bake for 15-20 minutes, until golden brown and crisp.

Tips for Perfect Croissant de Lune

Use high-quality butter for rich flavor and flaky layers.

Keep the dough and butter cold during lamination to prevent melting and ensure layer separation.

Be patient with the folding and chilling steps—they are key to achieving the signature flaky texture.

For a touch of sweetness, sprinkle a little sugar on the egg wash or fill with fruit preserves before shaping.
