Homemade Sour Cream Recipe Highlights
Sour cream is a fantastic ingredient to bake with, and I use it all the time because it adds a very distinct richness and moist texture to my baked goods, like in this Eggless Chocolate Bundt Cake and my favorite Easy Eggless Coffee Cake.
However, many of you have mentioned that this ingredient is unavailable in your region. And I totally get it! In fact, when I go to Europe, it has been challenging to find it, so I decided to share a little kitchen hack to make it at home.
The final homemade sour cream is rich and tangy. It’s so easy to make, and you only need 3 simple ingredients. After my testing, I found no difference between this sour cream and the store-bought one.
So let’s get started!
What is Sour Cream?
Sour cream is preserved soured cream. It can be eaten or used as an ingredient without cooking or baking. It has a tangy, tart taste backed by a rich, thick creaminess.

Ingredients Notes & Substitutions
- Heavy whipping cream: Make sure it has at least 35% fat content.
- Lemon juice or white vinegar
- Whole milk: Don’t be tempted to use low-fat cream and milk, or the sour cream will be too thin. We need the fat for the sour cream to set properly.
Heavy Whipping Cream or Heavy Cream vs Whipping Cream
Heavy whipping cream and heavy cream are essentially the same; both must contain at least 35% or more milk fat. However, whipping cream, or light whipping cream, is slightly different since it is lighter – it contains 30% to 35% milk fat. Heavy cream and heavy whipping cream are best for this recipe.

Eggless Baking Frequently Asked Questions
You’ve asked, and I’ve answered! Read on for a handful of answers to the most frequently asked questions about eggless baking.
Would this work with the plant based versions of heavy cream and milk?
Hello Kellie! I honestly haven’t tried that yet to advise, but I think it could work fine. Just ensure that the consistency of the substitute you choose is similar to that of heavy cream. Thanks for your interest in my recipe. Please come back and let me know how it turned out =)
Why do you need a kitchen scale?
Hello SophieMae! A kitchen scale provides precision, accuracy, and consistency in your cooking and baking endeavors. It can help you achieve better results, whether you’re a professional chef, avid home cook, of just a beginner.
Can I use cold cream or all the ingredients need to be room temp?
Hello Tamanna! It will depend on what recipe you are making. I always recommend following the recipe instructions exactly.
I’m attempting to make your homemade sour cream recipe and nowhere in the recipe did it say to use chilled heavy whipping cream/whole milk or room temp, will it make a difference if I use cold to room temperature??????
Hello Royal! Thanks for giving the recipe a try. I found that it really doesn’t make a difference since you have to leave the mixture for 24 hours over the counter at room temperature. Room-temperature ingredients for homemade sour cream might help with the fermentation process. But don’t worry if your cream and milk are cold. It should still turn out great! Let me know how it goes! 😊
