Prepare the skillet

• Preheat the oven to 180 °C.
• Press half of the cookie dough evenly into the bottom of an ovenproof skillet.

Add the Kinder layer

• Spread the Nutella over the cookie dough.
• Scatter the broken Kinder bars on top.

Top with the remaining dough

• Press the remaining cookie dough on the lid, flatten it and place it over the filling.
• Seal the edges so the filling stays inside.

Bake the skillet cookie

• Bake until the top is golden and the centre is just set.

Rest and serve

• Let the skillet cookie rest a few minutes before serving.
