Yes, you can make this delectable dessert ahead of time: 1. Pudding (without the sauce) can be baked earlier in the day, covered and stored at room temperature. It can also be wrapped and frozen for up to 1 month. Thaw overnight in refrigerator and then bring to room temperature. 2. Toffee Sauce is best when prepared just before serving, but can be prepared earlier in the day, cooled, covered and refrigerated.
