I have been searching and searching and making cakes that are supposed to taste like they came from a grocery store and am always disappointed in the results. I have a great white cake recipe. I love it. No complaints. Chocolate however, now that's been a bugger to try and figure out. I know most grocery stores & bakeries use cake mix along with ingredients added. Does anybody know how they do this? Specifically for chocolate or marbled. Thank you!
I've been thinking about your post for some days now. Several times I started to respond, then pulled back. The topic of creating a scratch cake to resemble a store-bought cake is at its essence the scratch vs box mix debate. And that is such a passionate topic among cake bakers as proponents on each side of the debate have very strong opinions on this subject.
I wanted to make sure that my own preferences (which is scratch) did not influence my response. So I hope this is an objective response as I believe the spirit of this forum is to promote and embrace the joy of baking in all it's forms.
So your question at hand is how to make a home baked chocolate cake more like a store-bought cake, in particular a chocolate marble cake.
The cake qualities that you are striving for our achieved through emulsifiers, type of flour, and mixing method.
EMULSIFIERS
BOX MIX
Since box cake mix contains the emulsifiers, box mix bakers strife to improve the flavor and increase batter yield as events cake require more batter. Modifying boxed mix for flavor usually entails replacing a large potion of the fat with an ingredient that has both fat and flavor, like yogurt or sour cream. Shawna McGreevy has cake recipes listed on her site. Her approach is an example how most box mix bakers alter their recipes.

SCRATCH CAKES
High ratio shortening. Replace the butter and/or oil with high ratio shortening. Commercially produced cakes rarely use butter for 3 reasons: 1) high ratio shortening is a superior emulsifier; 2) butter cakes have a shorter life shelf; 3) butter is more expensive.
High ratio shortening is specially formulated with emulsifiers. Retail shortenings, such as Crisco, do not contain the emulsifiers, thus will not produce the same results. High ratio shortening is sold to the trade, so its packaged in 50 lb tubs. However, a few bakery supply companies repackage bulk high ratio shortening for the retail market.
The preferred brand among commercial bakeries is Sweetex. Stratas Foods, the manufacturer of Sweetex, prohibits use of their trademark/copyright name on the labels of the repackaged shortening. So if you decide to purchase Sweetex in the smaller repackaged quantities, it is best to contact the supplier to confirm the brand of high ratio shortening.
Stratas Foods makes a liquid form of a high ratio shortening for cake batter. But I have never seen it repackaged for the retail market.
Check your local cake decorating suppliers or purchase online. Links to a couple of sources below.

Stratus Foods has a devil's food chocolate cake recipe using their high ratio shortening. I have never tried this recipe so I cannot vouch for it. But it is a place to start experimenting if you decide to try high ratio shortening. You will need to scale this recipe using baker's percentages as it's for mass production.

Lecithin: lecithin is an amino acid produced from soy or eggs. It not only emulsifies, but extends shelf life. In granular form it is widely available in health food stores and vitamin stores as people use it as a supplement. King Arthur Flour sells it in small repackaged quantities. They instruct 1 to 2 tablespoons per 3 cups of flour. I think that is quite vague. I would recommend a ratio of 20% to 25% by weight to the flour.

FLOUR
High ratio cake flour. The type of flour plays a major role in the finished product. A low protein, bleached, soft white wheat flour will produce the moistest, lightest, softest crumb. This type of flour is marketed as cake flour. Stella Parks wrote an article for Serious Eats explaining why bleached cake flour performs differently than unbleached flour (link below).
However, the retail cake flour in grocery stores it is not the same type of cake flour used in commercial baking. The commercial high ratio cake flour is more likely to be both bleached and heat treated. It's also very finely ground. This creates a flour that produces a cake with increased structural strength, without compromising the soft, delicate crumb by countering the effects of the sugar. It also produces a moister cake as the treatments increases flour absorbency rates.
The recipe I referenced above from the Stratas' website is most likely based on commercial cake flour. So if you use it, your results will not be exactly like theirs.

METHOD
High ratio method. The use of high ratio shortening and flour require a different mixing method. Rather than creaming butter and sugar, commercially produced cakes are mixed in two steps:
1. dry ingredients are mixed, then butter/shortening is mixed into dry ingredients.
2. Wet ingredients are mixed, then added to dry ingredients in 3 additions.
Use of high ratio ingredients and mixing method works best when it two ratio rules are followed:
1. Sugar is equal to or slightly more than flour by weight.
2. Liquid, including weight of eggs, is equal to flour by weight
Without commercial grade high ratio shortening and flour you will not achieve the same result as a commercially produced cake. But you can come close.
Since high ratio cake flour and shortening are not readily available, home bakers have come up with some variations on high ratio method. If you Google height ratio mixing method you'll see there are several different approaches.
Joe Pastry, a professional baker, has a high ratio chocolate cake recipe and mixing method that he modified for the home baker.

CHOCOLATE MARBLE CAKE
To make a marble cake, your batters will need to be:
1. close to the same consistency
2. bake at the same temperature, for the same time, for the same size pan
So if one batter is very heavy and thick and the other very light weight, it's not a good match. If one batter bakes at 325 and the other at 350, that's not a good match. If one batter requires 30 minutes to bake and the other requires 50 minutes to bake, that not a good match.
Since chocolate and vanilla cakes are formulated with different ingredients, different weights of flour, and require different levels of fat and hydration, it is not advisable to produce and divide a vanilla cake recipe, then add cocoa powder to one portion.
Rather, develop separate vanilla and chocolate recipe that is to your taste and use them to create a marble cake. While marble is a technique, not a recipe, the batters still need to be comparable in texture and weight to be compatible.
