Spread the Nutella over the puff pastry, leaving a small border.
Sprinkle the pecans over the Nutella.
Starting at the long edge, roll it into a log and gently press/pinch the long edge closed.
Cut in to 12 equal slices and place on a baking sheet. Brush with egg wash.
Bake at 425 degrees for 15 minutes. Let cool for ten minutes then sprinkle with powdered sugar and serve!
Notes
A couple of tips:
If you use frozen puff pastry you will need to take out one sheet and let it sit on your counter for about 30 minutes, then gently unfold it and roll out with a rolling pin to seal cracks and thin it out just a little. If you use the refrigerated, it’s all ready to go!
Once you have your log rolled up, to get even cuts, start by cutting your log in half, then each piece in to half again, then each of those pieces in to thirds!
