Gourmet cooking skill

Hi @thegirlwhowilldo

you probably mean the black and white and the white and black cakes. You should indeed have both from level 1 gourmet cooking.

For the white and Black cake you'll need the Up All Night DLC (Digital Deluxe Upgrade). Do you own that ?

The other should show up though. 

Are you using mods/cc in your game ?

That explains why you don't have the one that comes with the content.

Which recopies do you have ? Are you missing any others ?

Have you tried repairing the game or sorting the list by name for example ? 

Right click on the base game in Origin and choose repair game.

No but backing up your save is always a good idea
