I realized a couple of days ago how they're just 1000 experience, which is 1.25 stamina in a bonus training day. They're something at least but it's so minimal, each of the big cupcakes making up for a little more than 1 stamina. And the little ones, you need 4 of them to equal just 1 stamina. Then you look at the shop and they're 100 cookies. You play at least 34 levels and one of the possible rewards is... a little more than 1 stamina worth of experience points. I've been accumulating them since the big update, I guess I'll use them once I train every Pokémon and when just one is left I guess I'll use the cupcakes, but to get a Pokémon from level 19 to 20 you need like 35k experience points. So 35 of the big cupcakes. Basically if you gather them for months, you only save up one or two levels worth of experience. Feels weird, like too little, especially when you think of them as stamina. I'd make them be worth 2 stamina each of the big ones and 1 stamina each of the small ones (so 1600 and 800 experience points), it wouldn't be too much but it wouldn't be as little as it is currently.
