Kirby's Epic Yarn has a whole Treat Land (even if only two levels are particularly food themed).

Donkey Kong Country Returns also has that bonus level where you're hopping on all the different fruits.

Super Mario World and Crash 4

I've realized that I worded this poorly, I was moreso looking for levels made of food. Though Chocolate Land from Mario World could be made of it so it'll still be included.

rayman legends has Fiesta de Los Muertos which is entirely made of cakes, cooking utensils, and other foods

Coffee and Donuts from Travis Strikes Again might count?
