Step1. Making the croissant dough1. Mix together the flour, sugar, salt, and yeast in a mixing bowl.2. Slowly pour in the warm milk, stirring until a dough forms. Knead gently on a lightly floured surface for 5 minutes until smooth.3. place the dough out in a bowl, then cover with plastic wrap and refrigerate at least 1 hour
Step2. add the layer of nutter1. Roll the chilled dough out onto a lightly floured surface into a rectangle.2.Place the cold butter slices on one half of the rectangle and fold the dough over to enclose the butter. Press edges to seal in butter.3. Roll out the dough, fold it in thirds like a letter, and continue the process two more times, chilling for 30 minutes between turns. This is how that flaky croissant texture is achieved.
Step3. Prepare the cookie dough filling1. Combine the softened butter and sugars in another bowl until smooth.2. Add the egg, vanilla extract, and salt. Mix until well combined.3..Gradually add the flour and stir in the chocolate chips or crumbs.4. Cover and refrigerate the cookie dough until ready to assemble the croissants.
Step4. assemble the cookie croissant1. Roll out the chilled croissant dough into a large 1/4-inch-thick rectangle.2. Spread cookie dough evenly over the croissant dough, or, place a small marble-sized ball of cookie dough on the wide end of each triangle before rolling.3. Roll and shape as you would with traditional croissants: cut triangles and curl each triangle from the wide end to the point to create crescent shape.4.Put the rolled croissants on a parchment-lined baking sheet, cover them with something, and let them rise in a warm spot for 1-2 hours, or until they have doubled in size.
Step5. bake cookie croissant1. Preheat your oven to 375°F (190°C). 2. Brush each croissant with the egg wash, then sprinkle with sugar and additional chocolate chips if desired.3. Bake for 20-25 minutes, or until the croissants are golden brown and the cookie dough centers are slightly gooey.4. Let them cool for a few minutes before serving, although they’re best enjoyed warm and fresh from the oven.
