It’s been more than a year since the release of Assassin’s Creed Unity, and finally someone has figured out what’s up with the cakes scattered throughout the game’s setting of Paris during the French Revolution.

After a year of Ubisoft letting players eat cake without knowing why, Brett from UbiCentral finally has the Easter Egg figured out in the video above (thanks to a little assistance from the developers at Ubisoft who made the game). In fact, there are five cakes in the game that players can find and eat, and locating all five triggers a special, extra-tough battle with a man standing on top of a giant cake—and it’s good for an achievement or trophy, as well as lots of loot.

Kotaku reports who the cake guy actually is: he’s the Marquis de Bullion, who appeared in an early demo of Assassin’s Creed Unity as a bad guy but who was seemingly cut from the game. Turns out he’s been there all along, lying in wait, with a bloodlust matched only by his amazing confections.

Check out Brett’s video above for a full rundown of exactly how to find and defeat Assassin’s Creed Unity’s Cake Boss.
