Pre-heat oven to 375F / 190C. Grease and flour or spray a 4- 6 medium size muffin tin. Place jar of Nutella in fridge for at least 3-4 hours or until very cold and firm. You could also place spoonfuls of Nutella on a parchment paper lined cookie sheet and then freeze them for an hour then place one in the middle of each square.
Thaw the puff pastry if frozen, unroll and using a rolling pin, roll to even it out but do not make it too thin, cut into 4- 6 squares, make sure you leave a strip for cut outs or decorator ropes.
Place a scoop of Nutella in the middle of each square, brush the edges with milk and starting from the opposite ends bring up the corners to meet, do this again with the remaining corners (see photos) and squeeze to close. Decorate with twisted strips of pastry or cut outs. Place in prepared muffin tin, brush with milk, bake for approximately 20-25 minutes or until golden brown and baked through. Let cool enough to handle, dust with powdered sugar and serve. Enjoy!
Notes
My puff pastry was 13x10 inches (33 x 25 cm), I made 4 squares each 5 x 5 inches / 12.5 x 12.5 cm. The remaining dough I made flower cut outs.
How to store these pastries?
This Nutella puff pastry recipe is really best the day it is made! If you have any leftovers, you can store them in a parchment paper lined airtight container at room temperature or in the fridge. The fridge may help keep the pastry crisp.
Can I reheat leftover pastries?
You can reheat the Nutella pastry dessert in the air fryer for a few minutes or the microwave but be careful as they might as the flaky pastry can be ruined quickly. Again, try to enjoy them fresh the first day they are made for best results!
