From my experiences…
If the cakes are not DRY, they will grow mold. I would discard them. Your call. Depends on many things.
You WANT the mold and bacteria already populating the bonsai/ pot to digest the organic material naturally.

NOTE:
“I also use all commercial fertilizers to make mine.” ?
The REASON you use organic materials is to SOFTLTY and slowly release the nutrients; and to encourage the bacterial biome. The inorganic fertilizers , if used in a cake, are disolved QUICKLY and washed through/ maybe absorbed and utilized. Big hit of NPK. I recently overfertilized (organic) a in-ground ponderosa. Grew like crazy. Killed it. Too much nitrogen… My ruhbarb plant loved the same treatment…
live and lirn…
