When I was first learning to bake, I always wondered what was so special about ready-made mixes. In my mind, cake really wasn’t that complicated. Most cake recipes that I found online always called for some combination of flour, sugar, eggs, salt, and butter. So, why was it that the boxed cake mix always resulted in the same, consistent success, while baking from scratch yielded uncertain results?
What is in Cake Mix?
Cake mix is a box of conveniently measured out dry ingredients. All the baker needs to do is add eggs, some kind of fat, like oil, and a liquid, like water or milk. But what exactly makes up those dry ingredients?
According to the Betty Crocker website, their yellow cake mix consists of quite recognizable ingredients, including flour, sugar, corn syrup, baking soda, and corn starch. These match the ingredients one could think of in a normal recipe. The flour makes up most of the cake, while the sugar and corn syrup are for sweetness. The baker would add in the water, eggs, and fat (vegetable oil) on their own, so the question lies in the rest of the ingredients.
The Extra Additives
The rest of the ingredients of the Betty Crocker yellow cake mix make up less than 2% of the ingredients. However, they are extremely important to the stability of the cake. According to the label, these ingredients are monoglycerides, dicalcium phosphate, sodium stearoyl lactylate, xanthan gum, and cellulose gum. These ingredients are additives that help maintain the texture, stability, and shelf life of the mix.

- For instance, dicalcium phosphate is a tasteless, odorless additive that is usually included along with flour. It is meant to break up the ingredients evenly in the baking process and improve the consistency of the flour (Enax et al., 2022).
- Additionally, sodium stearoyl lactate is an additive that is also used as a stabilizer and emulsifier in processed foods (FAO & WHO, 1996). As a stabilizer, its job is to make sure that the food’s texture and taste maintain their quality during extended times on the shelf. As an emulsifier, its job is to allow ingredients like oil and water to mix together.
- Xanthan gum is also an ingredient commonly used in both food, polishes, and cleaners. Its job is to act as a stabilizer and thickener in convenience foods. More specifically, its job is to retain moisture in bakery goods and trapping gas in ready-made cake mixes so that they bake better (Katzbauer, 1997).
These are just a few of the extra ingredients that make cake mixes as consistent and convenient as they are today. They hold the ingredients together, enhance the taste and texture of the cake, and ensure that the results are similar each time. So, while, yes, cake mix is essentially the same mixture of flour and sugar than one might expect to find in a regular cake, there is a bit of science involved to help make sure it’s a bit easier each time!
