Counting calories is still very useful, because you learn what's "worth it".

For example there are protein bars that are supposedly healthy, but they have 150-250 kcal per 50g bar.

On the other hand there are these watery ice creams that have about 65 kcal per piece and feel just as indulgent if not more.

Other things that are very much "not worth it" on the enjoyement/kcal scale is bread and other pastries.

2 buns with ham is 500 kcal and feels like nothing. A whole pan of hot vegetables with some meat is +- the same and feels like a proper dinner.

Just do keto diet or carnivore then. Will be a lot easier. You have to give up the cake.

You might try an other diet that‘s more filling and creates less cravings. So less carbs and more protein and fat. I don‘t think that willpower really works in this regard long term. It only creates frustrations.

The big trick is figuring out mentally how to eat less without requiring willpower. It is possible. Depending on willpower is setting up for likely failure, IMO.
