Milk is often a key component of the original batter in many cake recipes. Because of its high water content, milk is employed as a moistening factor in the batter. In addition to this purpose, milk will interact with flour and sugar to create a cake that is more delicate but yet firm enough not to collapse.

Yet, many recipes, such as cornbread, propose using milk instead of buttermilk or sour cream. This is owing to their capacity to moisten the resultant cake batter even more.

If you want to use either, you may be asking, buttermilk versus sour cream, which is better?

What Is Buttermilk?

There are two meanings of buttermilk: one prevalent in India and one that originated in America. The American definition of buttermilk is important in this case. This variation is just ordinary milk fermented with vinegar or lemon juice. As a consequence, lactic acid bacteria are prevalent. The resultant sour milk is good for baking since it contributes to the creation of a sensitive and softer cake. This cake may have a lovely yet somewhat acidic flavor in certain situations.

All you need is vinegar. Just combine one liquid measuring cup lukewarm milk with one tablespoon and set aside for 10 to 15 minutes. The finished mixture will resemble curdled milk and may be easily substituted for ordinary milk in any cake recipe. If you’re short of milk, a suitable buttermilk replacement is watered-down plain yoghurt. Full-fat milk and lemon juice are used to produce homemade buttermilk.

What Is Sour Cream?

Sour cream, often known as soured cream, functions similarly to buttermilk. Sour cream, on the other hand, will employ milk-based cream rather than fermented milk. From here, the procedure is quite similar. The mixing of milk cream with lemon juice or vinegar produces a soured cream.

Even the method of creating sour cream is identical. Both buttermilk and sour cream are manufactured from the same material combined with the same amounts of lemon juice or vinegar. In this situation, one cup of milk cream and one tablespoon of lemon juice or vinegar.

Nevertheless, the curdling process will take longer in this case. One hour is the very least length of time necessary before it can be added to a cake batter. But, overnight in the fridge yields the finest results. If you wish to use sour cream but don’t have the essential components, you may substitute greek yoghurt.

How Are Buttermilk and Sour Cream Different?

As previously stated, buttermilk and sour cream share many similarities. These are both basically milk-based dairy products that have been fermented by the addition of lactic acid bacteria similar to those found in lemon juice or vinegar.

Moreover, by interacting with baking soda or baking powder in the recipe, both chemicals will substitute milk and function as a leavening agent. The resultant cakes will be softer and more supple, with a somewhat acidic flavor.

So, what exactly is the difference between them?

The primary distinction between buttermilk and sour cream is that the former will contain more water. Meanwhile, the latter will have a higher fat content. Because of this difference, a cake made using either will be softer, more tender, and somewhat crumbly, but the consistency will be drastically different.

If you’re looking for something creamy, sour cream is the way to go. Buttermilk will provide a lighter cake with a comparable consistency to ordinary milk. Sour cream, on the other hand, will result in a thick cake. As a consequence, most individuals prefer the outcomes provided by buttermilk. Yet, if density is important to you,

But, since baking soda has more leavening power than baking powder, you should use it instead of baking powder. In addition, sour cream or buttermilk measurements should be more cautious than standard milk measures. This is due to the fact that if utilized in excess, the cake may become excessively soft and collapse or crumble.
