It spreads beautifully, pipes well, and works on almost anything, including chocolate cake, vanilla cake, cupcakes, brownies, and sheet cakes. If you usually find buttercream too sweet, this chocolate sour cream frosting is the one to try. It has that rich chocolate flavor you want, without the heavy, overly sugary finish.

Baking Tips
- Using a kitchen scale is a total game changer for baking. It makes measuring ingredients super precise, so your recipe comes out perfect every single time. Plus, fewer measuring cups means less cleanup, and who doesn’t love that? Invest in one, and you’ll wonder how you ever baked without it!
- I absolutely love baking with fine kosher salt, it gives the perfect balance of flavor. Table salt, on the other hand, can be a bit too harsh, so if you're using it, be sure to cut the amount in half to avoid over salting your treats.
- Always check your oven temperature! Ovens can be sneaky, sometimes running hotter or cooler than what the dial says, and that can really affect how your baked goods turn out. For the most consistent results, I recommend using an oven thermometer to make sure your temps are spot on every time
How to make frosting thicker or thinner
- To make it thicker: Add more powdered sugar, a few tablespoons at a time, and mix on low until incorporated. Powdered sugar thickens the frosting while keeping it sweet and smooth. This is best if you want the frosting to hold a piped shape, sit between cake layers, or stay sturdy on cupcakes.
- To make it less sweet while thickening: Add a little extra sifted cocoa powder instead of only powdered sugar. Cocoa powder helps thicken the frosting and deepens the chocolate flavor. Add it slowly because too much can make the frosting taste dry or bitter.
- To make it fluffier and more stable: Beat the frosting on medium high to high speed for a few minutes after everything is incorporated. This adds air and helps the frosting become lighter, thicker, and easier to spread.
- To make it thinner: Add a teaspoon of milk or heavy cream and mix until smooth. This loosens the frosting while keeping that tangy, creamy flavor. Add just a little at a time because milk can thin the frosting quickly.
- To make it smoother for spreading: Let the frosting sit at room temperature for a few minutes, then beat it again. Sometimes frosting feels too thick simply because the butter or sour cream is too cold.
- For piping: Keep the frosting thicker so it holds its shape. Add powdered sugar or cocoa powder slowly until it looks fluffy, sturdy, and pipeable.
- For spreading on cakes or brownies: A slightly softer frosting works best. Add a tiny bit more sour cream if needed, then mix until creamy and smooth.
Sour Cream Chocolate Frosting Ingredients
- Cocoa powder: The cocoa powder is where most of the chocolate flavor comes from, so use a cocoa powder you really love. Natural unsweetened cocoa powder works great here, but make sure it is sifted before adding it to the bowl. Cocoa powder can be very lumpy, and once those lumps are in the frosting, you will not be able to beat them out easily.
- Sour cream: Use high quality, full fat sour cream for the best flavor and texture. Do not use low fat sour cream because it can make the frosting thinner and less rich. I also recommend using a brand you already like the taste of, because the flavor does come through. Make sure the sour cream is cold before adding it to the frosting.
- Butter: Use room temperature butter so it beats smoothly into the frosting. Salted or unsalted butter both work, but I personally love salted butter in frosting because it balances the sweetness so well. If you use unsalted butter, do not skip the added salt.
- Vanilla extract: Vanilla is key because it rounds out the chocolate flavor and makes the frosting taste more finished. Even though this is a chocolate frosting, the vanilla makes a big difference.
- Powdered sugar: Make sure your powdered sugar is lump free before adding it. You can whisk it well or sift it. This helps keep the frosting smooth and prevents little sugar lumps from showing up in the final texture.
- Salt: A pinch of salt enhances all the flavors and makes the chocolate taste deeper. If you are using unsalted butter, make sure you add it. Even with salted butter, a tiny extra pinch can help bring everything together.

How to Make Easy Chocolate Sour Cream Frosting From Scratch
- Using a mixer on low speed and then increase to medium, beat the butter and cocoa powder together in a large bowl until smooth and fully combined, it will look like a thick paste.
- Add the sour cream, vanilla extract and a pinch of salt, and mix until well incorporated. Gradually add the powdered sugar, mixing on low speed as you go.
- Then continue adding the remaining powdered sugar. Beat on medium high for 1–2 minutes, until the frosting is light, fluffy, and spreadable, beating long enough also ensures the powdered sugar dissolves.
- Taste and adjust, if you prefer it a little sweeter, add a tablespoon more powdered sugar at a time, if it needs to be thinner add a little milk or sour cream, one teaspoon at a time.
Hint: After refrigerating or freezing, always mix the frosting again with a mixer before spreading or piping. This brings the texture back and makes it creamy again.
Sour Cream Icing Pro Tips
- Make sure the cocoa powder and powdered sugar are lump free: This is one of the most important steps for a smooth frosting. Sift them or whisk them really well before adding them to the bowl.
- Start the mixer on low: When adding cocoa powder and powdered sugar, beat on low first. If you start on medium or high, you will absolutely make a mess. Once the dry ingredients are mostly incorporated, then you can turn the speed up.
- Use a kitchen towel around the bowl: To avoid a cocoa powder and powdered sugar cloud, loosely wrap a clean kitchen towel around the mixer bowl while mixing on low. It helps keep everything contained.
- Whip it well at the end: Once everything is incorporated, turn the mixer up and beat the frosting on high until it is light, fluffy, and smooth. This final mixing step makes the frosting softer, creamier, and easier to spread.
- Use your favorite cocoa powder brand: Since the chocolate flavor comes mainly from the cocoa powder, this is the time to use a good one. A better cocoa powder will give you a better frosting.
- Add a pinch of salt: Salt does not make the frosting taste salty. It enhances the chocolate, balances the sweetness, and makes the frosting taste richer.
What to pair this sour cream frosting with!
- Chocolate cake: The obvious answer, but for good reason. This frosting turns a simple chocolate cake into a rich, bakery style dessert with major chocolate-on-chocolate energy.
- Vanilla cake: The contrast is so good. Soft vanilla cake gives you that classic birthday cake flavor, but a little more grown up and less sugary.
- Cupcakes: This frosting pipes beautifully once it is whipped, so it is perfect for tall swirls on cupcakes. Add sprinkles, chocolate curls, or mini chocolate chips and they instantly look party-ready.
- Brownies: If you have never frosted brownies, this is your sign. A thick layer of frosting makes brownies feel extra fudgy, rich, and almost like a little chocolate bakery bar.
- Sheet cake: This is perfect for a casual, cozy sheet cake. Spread it on thick, add sprinkles, slice it into squares, and suddenly everyone needs “just one more piece.”
- Layer cake: Because it is smooth and creamy, this frosting works so well between cake layers and around the outside. It gives the cake a rich chocolate flavor without making every bite feel too heavy.
- Yellow cake: Yellow cake and chocolate frosting are basically best friends. The buttery cake with the tangy dark chocolate frosting is nostalgic, simple, and so good.
- Banana cake: Chocolate and banana are already amazing together, but the sour cream in the frosting makes the whole thing taste extra balanced. It is cozy, rich, and a little unexpected.
- Coffee cake: A little chocolate frosting on a coffee-flavored cake is such a good move. The cocoa flavor pairs beautifully with espresso or coffee, especially if you add a pinch of instant espresso powder to the frosting.
- Sandwich cookies: Spread this between two soft cookies and you have the easiest homemade cookie sandwich. Chocolate cookies, vanilla cookies, sugar cookies, all fair game.
- Whoopie pies: This frosting makes an amazing filling for whoopie pies because it is creamy, chocolatey, and not too sweet. It gives that rich bakery-style center without feeling like straight sugar.
- Graham crackers: This is the lazy snack version, and I fully support it. Spread a little frosting on graham crackers for a quick chocolate treat that tastes like something you made on purpose.
Easy Cocoa Frosting Variations
- Add sprinkles: Add fun sprinkles on top of whatever you are frosting. This is perfect for birthdays, cupcakes, or a simple sheet cake.
- Add chocolate chips: Sprinkle mini chocolate chips or chopped chocolate on top for extra texture and even more chocolate flavor.
- Make it cinnamon chocolate: Add a little cinnamon to the frosting for a warm, cozy flavor. Cinnamon and chocolate are so amazing together, especially on chocolate cake or spice cake.
- Make it mocha: Add instant espresso powder to the frosting. Even a small amount will enhance the chocolate flavor without making it taste strongly like coffee. Add a little more if you want a true mocha frosting.
How to store sour cream and chocolate frosting
Room temperature: If you are using the frosting the same day, it can sit at room temperature for up to 4 hours, keep it covered and away from heat.
Refrigerator: Store the frosting in an airtight container in the refrigerator for up to one week. Before using it, let it sit at room temperature until softened, then mix it again with a mixer until smooth and fluffy.
Freezer: You can freeze it in an airtight container for up to 1 month. Thaw it overnight in the refrigerator, then let it soften at room temperature. Before using, beat it with a mixer to bring back the smooth, fluffy texture.
FAQs About Old Fashioned Sour Cream Chocolate Frosting
Why is my frosting grainy?
Your icing may be grainy if the cocoa powder or powdered sugar was not sifted first, because little lumps can be hard to beat out once they are mixed into the frosting. It can also happen if the butter was too cold and did not blend smoothly. For the smoothest frosting, sift or whisk the dry ingredients first, use room temperature butter, and beat the frosting on high at the end until it becomes creamy and fluffy.
Why is my frosting runny and thin?
Your icing may be runny if the sour cream was too warm, too much sour cream was added, or the frosting was not mixed long enough to become fluffy. To fix it, add more powdered sugar a few tablespoons at a time until it thickens. You can also add a little extra sifted cocoa powder to thicken it while keeping that rich chocolate flavor!
