Changes and Hints
You may make it without nuts by removing the walnuts or pecans. An additional variation is to add a pinch of flaky sea salt for a salted toffee flavor. Substitute white chocolate or a flavored kind (dark, milk, etc.) for the semisweet chips, or add a pinch of espresso powder for a mocha flavor if you’re in the mood for something unusual. In the spirit of the season, you might garnish it with crushed peppermint for an extra festive touch.
