Speaking as an American, this is a part of American culture that's so weird -- using a pre-made mix as a base for a recipe that it's not designed for. That recipe looks like it just has flour, cocoa powder, baking powder, and salt pre-mixed (with a load of other garbage you probably don't need). People don't seem to realize that you can just buy those ingredients yourself. It doesn't take that much extra time to meas…
I bet you couldn't consistently make a cake even half as good as a box mix for even triple it's cost. People who don't bake often then baking is just throwing some stuff together and heating it up. It's very hard to get consistent results! It's literally an exact science. Did you weigh all the ingredients exactly? Did your mix and sift them evenly? Is your leavening agent fresh? Did you account for the humidity in yo…
If I use my eggs from neighbor's chickens, fancy chocolate, and organic milk from a local dairy, the cake is going to taste better (90% from the better chocolate honestly).
Quality improvements are easy.
Consistency is harder, but anyone with a kitchen scale and half an eye for detail should be able to pull it off. It takes me 3 or 4 goes at a recipe before I get super consistent with it, but it isn't rocket science (which also demands consistency!)
> What about a smaller cake or bigger one?
Boxes don't help here since their cooking instructions are for a fixed dimension, changing the cake size significantly for even boxed cakes requires understanding what you are doing. Again, not hard, but it isn't a win for box cakes.
