Preheat the Oven: Crank it up to 350°F (175°C).
Prepare the Croissants: Slice the buttery beauties in half and lay them out on a baking sheet lined with parchment paper—no sticky business here.
Stuff the Croissants: Manually stuff cookie dough into croissant halves, ensuring it’s well spread but not overstuffed.
Egg Wash: Generously brush the tops with your egg wash because everyone loves a shiny crookie.
Bake: They go into the oven for 15-20 minutes until golden perfect.
Serve Warm: The crookie is at its peak straight out of the oven—crispy outside and gooey in the middle.
