Carefully slice each croissant horizontally, almost all the way through, like you're making a sandwich.

Gently open up each croissant and spread a generous layer of Nutella on the bottom half.

Arrange the sliced strawberries on top of the Nutella layer.

Carefully close the croissants, pressing down gently to secure the filling.

Place the filled croissants on a baking sheet and bake in a preheated oven at 350°F (175°C) for about 8-10 minutes, until golden brown and slightly crispy.

Dust with powdered sugar for a nice finishing.

Remove from the oven and let them cool slightly before serving warm.
