Preheat Smoker - Set smoker to 200 degrees (F) using a fruitwood. We prefer cherry or apple for the sweeter smoke influence.
Smoke Hazelnuts - Layout hazelnuts on a baking tray and place them on the smoker for 60-90 minutes, checking every 30 minutes on the status of the hazelnuts (see note one). When done, remove and cool. If there is any skin still on, remove after cooling.
Smoked Hazelnut Nutella
Blend: In a food processor or strong blender place the hazelnuts and blend for about 2 minutes until a paste forms. This takes time. At first, it looks like chopped nuts, but keep going, pausing periodically to push down the sides until a paste forms (similar to peanut butter).
Combine: Add melted chocolate, powdered sugar, cocoa powder, hazelnut oil, vanilla, and salt, and puree until combined and creamy.
Store: Pour into an air-tight container (like a mason jar) and keep at room temperature for up to 2 weeks.

Notes
Note 1: Not all hazelnuts are created equal. Some will release more oils than others, creating a creamier result. If yours isn't as creamy as you'd like add additional hazelnut oil to get the consistency you like (add 1 tablespoon at a time).For the oil: If you can't find hazelnut oil, substitute it with another neutral oil like grapeseed or avocado oil.Chocolate: I prefer the sweet taste of milk chocolate, but you can easily sub semi-sweet or dark, or a combination of 2 or 3 of those.This will harden a bit after a day. It will still remain spreadable, but not as liquidy as when you blend it. If you want to get it back place it in the microwave and heat in 15-second increments, stirring between, until you get it back to the consistency you like.
