Does Saltine Toffee Need to Be Refrigerated?
No — saltine toffee (Christmas Crack) does not need to be refrigerated; the boiled butter-and-sugar toffee and chocolate topping are low-moisture, high-sugar and therefore shelf-stable, so an airtight container at cool room temperature keeps it good for one to two weeks, though refrigerating it firms the chocolate and can stretch its life to a month or more.

What it means
- Like most cooked-sugar candy, saltine toffee is a low-moisture, high-sugar food, which makes it naturally shelf-stable at room temperature.
- The chocolate layer stays glossiest and snappiest when kept cool, so a warm kitchen or summer heat is the main reason to chill it.
- Refrigerating or freezing extends shelf life but can cause condensation, so let chilled toffee return to room temperature before opening the sealed container.
Risks & deadlines
- In humid conditions the toffee can absorb moisture and turn sticky or soft, so keep it tightly sealed with the air pressed out.
- At warm room temperatures (above roughly 75-80F) the chocolate can bloom or soften, so refrigerate if your kitchen runs hot.
