Food earns one XP per two coins spent regardless of what kind of food you make, so it's only worth baking cakes if you're actually earning coins at a rate of five million per bakery per two days. I just stick with pizzas mostly - it lets me bake food at a near-constant rate and still get a net increase on my money at the same time.

As for the buying and selling buildings for money, doing so with a mini-mine earns you one XP per coin spent, and also gives diamonds.
