Seen a lot of post and questions regarding their missing cake profit which is not true but a bit of misunderstanding.
The rewards are always added automatically to your initial staking position, if you check or remember you initial staking it all checks out.
If you don't remember your initial staking amount, you can check your transaction history, and if you have a lot, you can use other tools like debank.
Here are the steps:

2 – Select BSC
3 – Filter CAKE
Also, using https://bscscan.com and browsing your wallet and filtering cake does the trick.
The steps above will help you remember and see your transaction hostroy on the fixed cake pool and you will understand that it all checks out in numbers. Your rewards are already added to your initial staking.
