Variations & Tips
For a twist, try adding a sprinkle of sea salt on top of the chocolate layer before it sets for a sweet and salty combination. You can also substitute almond butter or peanut butter for the hazelnut butter if you prefer. For a festive touch, consider adding a handful of chopped hazelnuts or other nuts to the base mixture for extra crunch. If you're feeling adventurous, a dash of cinnamon or a splash of espresso powder in the base can add a new depth of flavor to these delightful bars.
