In Cake Mania: Back to the Bakery, there is typically a penalty for leaving a cake order unfinished or letting it expire. However, if you want to remove the penalty or make it easier for yourself by allowing uncompleted orders without any penalty, there is no direct in-game option or official cheat code for this feature.

But you could try the following:

If you have a cake left over at the end of a round do not throw it away. Give the last customer his order but do not pick up the money yet. Now go pick up the cake that was not bought and then pick up the coins. You will not receive any penalty and it will show that you have lost no cakes.

This works for the PC version only but not the PS2 version.

You could also try:

1. Modding the Game (If Possible)

2. Using Cheat Codes (if any)

While cheat codes aren't officially listed for the game, some players have found ways to unlock all levels, make the game easier, or get bonuses. It’s possible that, through a cheat or hack, you could avoid penalties, but it may depend on the version of the game you’re playing.

3. Save Game Editing

In some cases, players modify their save files to bypass certain mechanics or change the game’s difficulty. This method requires more technical knowledge, so you'd need to find specific save file editors or guides for Cake Mania: Back to the Bakery if you wanted to explore this route.
