Each ingredient in this recipe plays a crucial role in building the cake’s incredible flavor, moisture, and texture. The combination is simple, but every component is essential to achieve that deeply satisfying chocolate experience.
- 1 cup butter (softened): Provides richness and a creamy texture to the cake batter.

- 4 large eggs: Bind the ingredients and contribute to the cake’s structure.
- 1 Tablespoon vanilla extract: Enhances all the flavors with a classic aromatic touch.
- 2 2/3 cups all-purpose flour: Forms the base of the cake and gives it body.
- 3/4 cup unsweetened cocoa powder: Brings an intense, rich chocolate flavor.
- 3 teaspoons baking soda: Helps leaven the cake for a tender crumb.
- 1/2 teaspoon salt: Balances sweetness and enhances chocolate notes.
- 1 1/3 cups sour cream: Adds wonderful moisture and a slight tang that brightens flavors.
- 1 1/3 cup boiling water: Intensifies the cocoa’s flavor and ensures a smooth batter.
- 1/2 cup butter (for frosting): Creates a rich base for the chocolate frosting.

How to Make Sour Cream Chocolate Cake Recipe
Step 1: Get Your Oven and Pan Ready
Start by preheating your oven to 350 degrees Fahrenheit. Prepare a 10×15 inch glass baking dish by greasing it thoroughly with non-stick cooking spray to ensure your cake doesn’t stick and comes out perfectly every time.
Step 2: Cream Butter and Sugar
In a large mixing bowl, cream the softened butter and packed brown sugar together until the mixture is light and fluffy. This step helps incorporate air for a lighter cake texture. Then, add the eggs one at a time, beating well after each to create an well-emulsified batter.
Step 3: Flavor Base
Stir in the vanilla extract gently to infuse the batter with that warm, inviting aroma that’s essential to all great cakes.
Step 4: Mix Dry Ingredients
Sift together the flour, cocoa powder, baking soda, and salt in a separate bowl. Whisk these ingredients well to ensure even distribution and to prevent clumps from forming in the batter.
Step 5: Combine Wet and Dry
Add the wet mixture and the sour cream to the sifted dry ingredients. Beat everything with an electric mixer just until the mixture is well blended. Be careful not to overmix, as that can lead to a dense cake.
Step 6: Add Boiling Water
Pour in the boiling water and stir gently until combined. This hot water step helps bloom the cocoa powder, enriching the chocolate flavor and keeping the batter silky smooth.
Step 7: Bake the Cake
Pour the batter evenly into your prepared baking dish. Place it in the preheated oven and bake for about 45 minutes, or until a toothpick inserted into the center comes out clean. This is the moment when your kitchen starts smelling absolutely heavenly!
Step 8: Cool Before Frosting
Once baked, set the cake aside to cool completely. This step is crucial to ensure the frosting glides on smoothly instead of melting into the cake.
Step 9: Prepare the Chocolate Frosting
While the cake cools, melt the 1/2 cup butter in a microwave-safe bowl until just melted. Add in both the chopped unsweetened and semi-sweet baking chocolates. Microwave in 30-second bursts, stirring after each, until the chocolate mixture is perfectly melted and glossy.
Step 10: Finish the Frosting
In a large bowl, combine the melted chocolate mixture with powdered sugar, sour cream, and vanilla extract. Beat with an electric mixer until the frosting is smooth and creamy, ready for slathering over the cake.
How to Serve Sour Cream Chocolate Cake Recipe

Garnishes
A dusting of cocoa powder or a sprinkle of finely chopped nuts can add a beautiful contrast to your cake. Fresh berries, such as raspberries or strawberries, bring a fresh tartness that pairs delightfully with the rich chocolate.
Side Dishes
This cake pairs wonderfully with a scoop of vanilla ice cream or a drizzle of caramel sauce. For adults, a cup of robust coffee or a glass of bold red wine enhances the chocolate’s depth perfectly.
Creative Ways to Present
Try serving individual slices with a dollop of whipped cream and a sprinkle of chocolate shavings for an elegant touch. Cutting the cake into bite-sized squares and serving on a platter makes for a fantastic option at parties or potlucks.
Make Ahead and Storage
Storing Leftovers
Wrap any leftover cake tightly in plastic wrap or store in an airtight container to keep it fresh for up to 4 days at room temperature. Refrigerating it will extend its freshness but may slightly dry the cake if not wrapped well.
Freezing
You can freeze the cake, either frosted or unfrosted. Wrap it securely with plastic wrap, then aluminum foil, and freeze for up to 3 months. Thaw overnight in the refrigerator, then bring to room temperature before serving.
Reheating
If you prefer your cake slightly warm, microwave individual slices for 10–15 seconds. This will revive the softness and melt the frosting slightly, giving you a cozy, fresh-baked feel every time.
FAQs
Can I substitute sour cream with something else?
Yes! Greek yogurt or crème fraîche are excellent alternatives that provide similar moisture and tang, keeping the cake tender and flavorful.
Is this cake gluten-free?
Not as written, since it uses all-purpose flour. However, you can experiment with a gluten-free flour blend, but the texture might vary slightly.
What type of baking chocolate should I use?
The combination of unsweetened and semi-sweet baking chocolates balances bitterness and sweetness perfectly. Using only one type might make the frosting too sweet or too intense.
Can I make this cake into cupcakes?
Absolutely! Just reduce the baking time to around 20–25 minutes and check doneness with a toothpick. The moist crumb works wonderfully in cupcake form.
How long will the cake stay moist?
Thanks to the sour cream, this cake stays moist for several days if stored properly. For best results, consume within 3–4 days or freeze for longer storage.
