Golden cookies in Cookie Clicker typically appear every 5 to 15 minutes, with an initial spawn interval around 7 minutes and 30 seconds on average. The cookie stays on screen for 13 seconds but can be extended by upgrades. Upgrades such as Lucky Day and Serendipity double the frequency of their appearance and increase the duration they remain visible. With these upgrades, golden cookies can spawn as often as once every 75 to 210 seconds and stay visible for up to 52 seconds. Further upgrades and buffs from ascension, the garden, and the pantheon can significantly increase the frequency, potentially resulting in more than one golden cookie per minute for highly optimized players.
