Place the hazelnuts on a baking sheet (I used the sheet that comes with my toaster oven) and toast the nuts for 5 minutes.
While the nuts are toasting, melt the chocolate in the microwave or over a double boiler.
Transfer the hazelnuts to a food processor and process on high until smooth and creamy. Again, you might have to scrape the sides down as you go to help the nuts continue to blend. Once smooth, add the melted chocolate and process again to incorporate.
Transfer to a glass container and store in a cool dark place.
