Does a freshly made baked good with eggs need to be refrigerated overnight?

Generally, no, freshly baked goods with eggs do not need to be refrigerated overnight.

Here's why:

* Baking process: The high heat of baking kills most bacteria that could cause spoilage.

* Ingredients: Eggs are a primary ingredient in baked goods, and their proteins solidify during baking, making them less susceptible to bacterial growth.

* Short shelf life: Most baked goods, even with eggs, have a relatively short shelf life, regardless of refrigeration.

However, there are exceptions:

* Cream-filled pastries: Cream fillings can spoil quickly, so it's best to refrigerate these items.

* Custard-based desserts: Custards are egg-based and susceptible to bacterial growth, so refrigeration is recommended.

* High-humidity environments: If you live in a very humid climate, it's safer to refrigerate baked goods with eggs to prevent moisture buildup.

Best practice:

* Store baked goods at room temperature: In a cool, dry place, away from direct sunlight.

* Use within 2-3 days: For optimal freshness and taste.

* Refrigerate if unsure: If you're unsure about the shelf life of your baked good, it's always better to err on the side of caution and refrigerate it.

Ultimately, it's best to follow the specific storage instructions provided by the recipe or bakery.
