Start by preheating your oven to 350 degreesa.

Now you will spread your hazelnuts on a baking sheet and roast them for 10 minutes. Let them sit to cool once done.

Now grab your 10 inch tart pan and place with your unbaked pie crust, and press the pie crust into the tart pan.

In a new bowl add your chocolate, cocoa powder, and butter. Microwave until melted, I do 30 second increments stirring between each check.

Once mixed, let cool and set aside.

Now with your hazelnuts place in a towel and rub them around with part of the towel, to help remove the skins.

Place your hazelnuts in a food processor and pulse until the nuts are topped.

In your chocolate bowl add in your nuts, eggs, rum extract, and corn syrup. Mix until combined.

Pour into prepared pie crust and bake 40 minutes at 350 degrees. Stick a toothpick in the center to see if it comes out clean.
