# What You Need:
→ Croissants
01 - 6 large all-butter croissants (fresh or day-old)
→ Cookie Dough
02 - 6 tablespoons unsalted butter, softened
03 - 1/2 cup light brown sugar
04 - 1/4 cup granulated sugar
05 - 1 large egg
06 - 1 teaspoon vanilla extract
07 - 1 1/4 cups all-purpose flour
08 - 1/2 teaspoon baking soda
09 - 1/4 teaspoon fine sea salt
10 - 3/4 cup semi-sweet chocolate chips
→ Finishing
11 - 1 large egg, beaten (for egg wash)
12 - Icing sugar, for dusting (optional)
# Steps:
01 - Preheat the oven to 350°F. Line a baking sheet with parchment paper.
02 - In a medium bowl, beat together the softened butter, light brown sugar, and granulated sugar until light and fluffy.
03 - Add the egg and vanilla extract to the butter-sugar mixture and combine thoroughly.
04 - Sift together the all-purpose flour, baking soda, and fine sea salt, then fold into the wet mixture until just combined.
05 - Gently fold in the semi-sweet chocolate chips until evenly distributed throughout the dough.
06 - Carefully slice each croissant horizontally, leaving one edge connected to create a hinge, so they open like a book.
07 - Spoon 2 to 3 tablespoons of cookie dough into the center of each sliced croissant, gently spreading it evenly but not overfilling.
08 - Close each croissant gently and brush the tops with the beaten egg for a glossy finish.
09 - Place the filled croissants on the prepared baking sheet and bake for 16 to 18 minutes until golden and the cookie dough is set yet soft.
10 - Allow croissants to cool slightly before dusting with icing sugar if desired. Serve warm to enjoy the gooey center.
