In a blender, combine the garlic cloves, pine nuts, and basil. Add a little of the olive oil and turn on the blender. *You may need to stop the blender and push the basil leaves toward the bottom.
When the basil begins to blend with the garlic and pine nuts, slowly pour the remaining olive oil into the blender while it is running.
Once it is all incorporated, add in the finely grated parmesan and blend for about 10 seconds.
