I want to ask the best way to make hazelnut oil using an oven, a blender, and…cheesecloth?
(At this point no online article seems helpful).
My plan is to bake hazelnuts at 300 F for 8-15 minutes until surface has an oily sheen and is fragrant. Afterwards, put into a blender and pulverize until oil is extracted. Filter through cheesecloth.
Is this a sound methodology?
My goal is to mix the fragrant oil into my chocolate sauce recipe (which already has salt, vanilla, brown sugar).

A blender is the wrong piece of equipment for this - you need a tool to apply pressure to the hazelnuts, not to mince them to bits. You need a screw press oil-expeller.
Hand-cranked models similar to the one in this article start at $125 on Amazon, electronic models begin at just under $200, and then ramp up from there depending on capacity. Search for "nut oil press" and you'll find what you need.
