This Chocolate Walnut Biscotti has a wonderful crisp and crunchy texture that is perfect for dunking in our freshly-brewed coffee...or even in our hot chocolate. They are loaded with chunks of roasted walnuts. Please be reminded that toasting the nuts does not only removes the bitter taste but also enhances the sweet, rich and buttery flavor of the nut. Place walnuts on a baking tray and bake in an oven (180 degrees Celsius) for 10 minutes or until brown and fragrant. Remove from oven and let it cool before chopping coarsely.
