The Science Behind Sour Cream in Baking: What Does Sour Cream Do to Cakes?
When you put sour cream in a cake, it serves several important purposes. Let’s break down the science of this versatile ingredient.
1. Moisture: The Secret to a Tender Cake
One of the primary benefits of adding sour cream to cake recipes is moisture. Cakes have a tendency to dry out, especially if you’re working with dense batters or using ingredients that don’t retain much liquid. Sour cream helps lock in moisture, resulting in a tender, moist crumb that makes every bite delicious.
Sour cream’s lactic acid content is the key. This acid softens the gluten in flour, helping to maintain a tender structure. This is particularly important in cakes like pound cakes or bundt cakes, where achieving the right balance between density and moisture is crucial.

2. Richness and Creaminess: Enhancing Cake Flavor
What does putting sour cream in a cake do beyond just adding moisture? It also boosts richness and creaminess. The fat content in sour cream makes your cake denser and adds a luxurious mouthfeel. If you want a cake that tastes rich and indulgent, sour cream is a perfect choice. This is especially true for chocolate cakes or red velvet cakes, where a creamy texture can elevate the overall experience.
In fact, substituting sour cream for milk or cream in cake recipes can result in a denser, more flavorful cake. The fat in sour cream makes the cake richer, while the tanginess enhances the sweetness of other ingredients, creating a balanced flavor profile.
3. Tanginess: Enhancing Sweet and Savory Flavors
Sour cream also brings a subtle tang to cakes, balancing the sweetness of sugar or chocolate. This tang is particularly useful in recipes that can become overly sweet, like vanilla or lemon cakes. The acidity of sour cream acts as a flavor enhancer, adding depth and complexity without overpowering the other flavors in the cake.

4. Sour Cream as a Leavening Agent
When combined with baking soda, sour cream acts as a leavening agent in your cake batter. The acid in sour cream reacts with the alkaline baking soda to produce carbon dioxide, which helps the cake rise. This reaction results in a lighter, fluffier cake texture, which is why sour cream is often included in recipes that require a soft, airy crumb.
5. How to Use Sour Cream in Your Cake Recipes
Now that you know what putting sour cream in a cake does, let’s explore how to use it effectively. Here are a few tips:
- Substitute for Milk: You can replace milk with sour cream in most cake recipes for added richness. Just use an equal amount.
- Adjust the Sugar: Because sour cream is slightly tangy, you may need to adjust the sugar in your recipe to maintain the desired sweetness.
- Don’t Overmix: Sour cream can make your batter heavy if overmixed, so be sure to fold it in gently.
How Sour Cream Affects Different Types of Cakes
One of the most fascinating aspects of sour cream is its versatility across various cake types. Whether you’re making a dense pound cake or a light chiffon cake, sour cream can adjust the cake’s texture to your preference.

Sour Cream in Pound Cakes
Pound cakes are known for their dense and buttery texture. Adding sour cream to a pound cake recipe enhances the moisture, making the cake rich without being too heavy. The lactic acid in sour cream breaks down the gluten strands in the flour, which results in a more tender crumb while still maintaining the cake’s signature density.
Here’s how to adjust your pound cake recipe to include sour cream:
- Tip: If your recipe calls for milk, substitute half the amount with sour cream to add moisture and tang. This works especially well in recipes where you want to avoid a dry, crumbly cake.
An example of this would be the classic lemon pound cake, where the tang of the sour cream complements the citrus notes beautifully. Not only does the sour cream prevent the cake from drying out, but it also balances the sweetness of the lemon glaze, providing a more complex flavor profile.
Sour Cream in Chocolate Cakes
Chocolate cakes benefit from sour cream in more ways than one. Chocolate has a tendency to dry out when baked, especially in recipes that use cocoa powder rather than melted chocolate. Adding sour cream helps keep the cake moist and enhances the chocolate flavor, as the tang from the sour cream contrasts with the bitterness of the cocoa.
In recipes for chocolate sour cream cake, bakers often use a generous amount of sour cream to create a decadent, fudgy texture. This technique works best for cakes that are layered or frosted, as the added moisture ensures the cake stays tender even after several days.
- Tip: Use sour cream in chocolate cakes that call for vegetable oil instead of butter for an extra tender crumb. The combination of fat from both the sour cream and oil produces a cake that is melt-in-your-mouth soft.

Sour Cream in Cheesecakes
Though cheesecakes are a different type of cake altogether, sour cream is a popular ingredient used to enhance their texture. In many New York-style cheesecake recipes, sour cream is mixed into the batter to create a creamy, rich filling that holds its shape well after baking. The acidity in sour cream helps to stabilize the cheesecake, preventing cracks and ensuring a smooth, dense texture.
- Tip: When using sour cream in cheesecakes, always ensure the ingredients are at room temperature before mixing. This prevents lumps and ensures a silky smooth filling.
Sour Cream’s Role in Layer Cakes and Frosting
While sour cream is widely recognized for its impact on cake batter, it can also be used in frostings and fillings, making it a versatile addition to any layer cake.
Sour Cream in Buttercream Frosting
Sour cream can be used to add a tangy flavor to buttercream frosting. By incorporating sour cream into a traditional buttercream recipe, you create a frosting that balances out the sweetness with a slight tartness, making it ideal for cakes that have a sweet base, such as vanilla or red velvet cakes.
- Tip: Start by adding a tablespoon of sour cream to your frosting, then adjust based on the level of tanginess you desire. You can also add sour cream to whipped cream frostings for a lighter option that’s still packed with flavor.
Sour Cream as a Filling for Layer Cakes
Sour cream also works well as a filling between cake layers, especially when combined with fresh fruit or jam. The creaminess of the sour cream pairs well with fruit flavors like strawberries, raspberries, or blueberries, creating a refreshing filling that contrasts with the richness of the cake.
A popular example of this is a strawberry shortcake layered with sour cream and whipped cream filling. The sour cream cuts through the sweetness of the berries and cake, making for a more balanced dessert.
How to Substitute Sour Cream in Cake Recipes
Though sour cream is a fantastic ingredient, there may be times when you need a substitute. Understanding how to substitute sour cream in baking without sacrificing quality is an important skill for any baker.
Greek Yogurt as a Substitute for Sour Cream
Greek yogurt is one of the most common substitutes for sour cream in cake recipes. It has a similar texture and tangy flavor, making it an excellent alternative when you’re out of sour cream or looking for a lower-fat option.
When substituting, use the same amount of Greek yogurt as you would sour cream. This swap works particularly well in cakes where the tanginess is a key flavor component, such as lemon or orange cakes. However, be aware that Greek yogurt may not add the same level of richness as sour cream, so the final texture might be slightly lighter.

Other Sour Cream Substitutes
- Crème fraîche: Crème fraîche is another option that offers a similar tangy flavor and creamy texture. Though it’s slightly milder than sour cream, it works well in most cake recipes.
- Buttermilk: Buttermilk can also be used in place of sour cream, though it’s much thinner in consistency. When using buttermilk, you may need to reduce the amount of liquid in the recipe to avoid making the batter too runny.
- Cottage cheese: If you blend cottage cheese until smooth, it can be used as a sour cream substitute. However, this option may alter the texture of the cake, making it less creamy than with sour cream.

Enhancing Cake Flavors with Sour Cream: Practical Tips
If you want to maximize the flavor and texture of your cakes with sour cream, consider the following tips:

- Tip #2: Bring sour cream to room temperature before adding it to the batter. This ensures even mixing and prevents lumps in the batter.
- Tip #3: Experiment with flavored sour cream. Some brands offer sour cream with hints of vanilla or other flavorings, which can add a unique twist to your cakes.
