History of Bake-stravaganza

Bake-stravaganza is a Dawning triumph: bake cookies in the Dawning Oven. The game data here tracks "Cookies baked (0/4)".

How to complete

1. Collect Essence of Dawning (best from Strikes, Gambit and Crucible per TheGamer) and cooking ingredients dropped by enemies; different enemy types drop different ingredients.
2. Bake cookies at the oven using a recipe. Masterworking the oven lowers the Essence cost per bake. Eva Levante hands out repeatable bounties that involve baking and delivering cookies.

Notes

The count differs by year: this wiki's data says 4, while a search summary for the 2022 event said 50 (not verified from an opened page). Seal and reward are unconfirmed; the Dawning's Star Baker seal has separate baking triumphs ("bake 6/13/20 types of cookies").
