What Is Sour Cream Chocolate Cake
Sour cream chocolate cake is a classic chocolate cake that uses sour cream in the batter instead of, or alongside, milk or buttermilk. The sour cream adds fat and acidity, which improves texture and enhances the chocolate flavor.
The cake is known for being:
- Extra moist
- Soft and tender
- Rich without being heavy
- Easy to slice and frost
It works well as a layer cake, sheet cake, bundt cake, or even cupcakes.
Why Sour Cream Makes Chocolate Cake Better
Sour cream is a powerful baking ingredient.
Here’s what it does:
- Adds fat for moisture and richness
- Adds acidity to activate baking soda
- Softens gluten for a tender crumb
- Balances sweetness with a slight tang
Unlike yogurt or milk, sour cream is thick, which helps create a dense yet soft structure that stays moist for days.
Flavor Profile You Can Expect
This cake doesn’t taste sour. Instead, it tastes deeply chocolatey, smooth, and balanced.
You’ll notice:
- Strong cocoa flavor
- Soft, velvety texture
- No dryness or crumbling
- A cake that pairs well with many frostings
It’s the kind of chocolate cake people ask for again.

Step-by-Step Sour Cream Chocolate Cake Recipe
This version makes a moist two-layer cake or one 9×13-inch cake.
Ingredients:
- 1 3/4 cups all-purpose flour
- 3/4 cup unsweetened cocoa powder
- 2 cups sugar
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1 teaspoon salt
- 1/2 cup oil or melted butter
- 2 large eggs
- 1 cup sour cream
- 1 teaspoon vanilla extract
- 3/4 cup hot water or hot coffee
Instructions:
Preheat oven to 350°F (175°C). Grease and line cake pans. In a large bowl, whisk flour, cocoa powder, sugar, baking soda, baking powder, and salt. Add oil, eggs, sour cream, and vanilla. Mix until smooth. Slowly stir in hot water or coffee. Batter will be thin. Pour into pans and bake 30 to 35 minutes for round pans or 35 to 40 minutes for a sheet cake. Cool completely before frosting.
Why the Batter Is Thin
A thin batter is normal and important.
It helps:
- Create a moist crumb
- Bake evenly
- Prevent dryness
Do not add extra flour to thicken it.
Best Frostings for Sour Cream Chocolate Cake
This cake pairs well with many frostings.
Top choices:
- Chocolate buttercream
- Cream cheese frosting
- Chocolate ganache
- Sour cream chocolate frosting
- Whipped chocolate frosting
Cream cheese frosting works especially well with the slight tang from the cake.
Tips for a Perfect Texture
To get the best result:
- Measure flour correctly, don’t pack it
- Use room-temperature eggs and sour cream
- Mix just until combined
- Do not overbake
- Let cake cool fully before frosting
Overmixing and overbaking are the biggest texture killers.
Common Mistakes to Avoid
Even simple cakes can go wrong.
Avoid these:
- Using low-fat sour cream
- Skipping the hot liquid
- Overmixing the batter
- Baking at too high a temperature
- Frosting while warm
Full-fat sour cream gives the best moisture and flavor.
Can You Substitute Greek Yogurt
Yes, but with adjustments.
If using Greek yogurt:
- Use full-fat
- Thin with 1 to 2 tablespoons milk
- Expect slightly denser texture
Sour cream still gives the best result.
Making It Extra Chocolatey
If you want deeper chocolate flavor:
- Use hot coffee instead of water
- Add 1/2 teaspoon espresso powder
- Use dark cocoa powder
- Add chocolate chips to the batter
These additions boost richness without changing texture.
Turning It Into a Bundt Cake
This recipe works well in a bundt pan.
Bundt tips:
- Grease pan thoroughly
- Bake 45 to 50 minutes
- Cool for 15 minutes before turning out
The cake slices cleanly and stays moist.
Cupcake Version
For cupcakes:
- Fill liners 2/3 full
- Bake 18 to 22 minutes
- Cool before frosting
They stay soft even after refrigeration.
Making It Ahead of Time
This cake is excellent for advance baking.
Make-ahead tips:
- Bake layers one day early
- Wrap tightly and store at room temperature

Flavor often improves overnight.
Storage Instructions

Refrigerator:
- Up to 5 days in an airtight container
Freezer:

Thaw at room temperature before frosting.
Gluten-Free Version
To make it gluten-free:
- Use a 1:1 gluten-free flour blend

- Let batter rest 5 minutes before baking
Texture will still be moist and tender.
Dairy-Free Option
You can make it dairy-free with swaps:
- Dairy-free sour cream alternative

- Dairy-free chocolate for frosting
Flavor remains rich and chocolatey.
Why This Cake Stays Moist for Days
