Desserts for Family Gatherings

Which dessert do people ask you to bring to a family gathering? Tell us what it is, the occasion it suits, and why it works well for your group.

Practical details are welcome: how you transport it, how many people it serves, and what you prepare ahead to avoid a last-minute rush. Credit and link to the original recipe, or share your own recipe in your own words.

If refrigeration or special handling is needed, provide a reliable source for any specific safety advice you include.
