How long do Halloween cookies last?

Homemade Halloween cookies usually last 3–4 days when stored in an airtight container at room temperature. For longer freshness, refrigerate or freeze the dough instead of the baked cookies.

How do you make Halloween slime?

For edible slime, melt green candy melts or white chocolate tinted with food coloring. Stir in marshmallow fluff for stretchiness and gooey texture. This combo creates the perfect slime for filling cookies.

How long do cookies last once made?

Most cookies stay fresh for 3–5 days at room temperature. These slime filled Halloween cookies keep their soft texture for about 4 days in an airtight container.

How long are Halloween chocolates good for?

Unopened Halloween chocolates can last several months if stored in a cool, dry place. Once opened, they’re best enjoyed within 2–3 weeks.

Do cookies go bad if left out?

Yes. If cookies are left uncovered, they’ll dry out within 24 hours. Always store them in a sealed container to preserve moisture and flavor.

Can you freeze cookie dough?

Absolutely! Shape the dough into balls, freeze on a tray, then store in a freezer-safe bag for up to 2 months. Bake from frozen with just 1–2 minutes added to the bake time.
