Hi Bold Bakers!
WHAT YOU GET: One of my most-used Bold Baking Basic recipes — Sour Cream! Knowing how to make sour cream is key for both your sweet and savory cooking and baking. So if you’re running low or just like to make everything from scratch, this recipe is for you! If you need any help, comment down on the page below. We respond to all comments!
From topping tacos and chili, to adding it to your cupcakes, rich chocolate cakes, and even my Sour Cream Banana Bread recipe, I use sour cream all the time. I always have some of my easy Homemade Sour Cream in the fridge, so using this simple method means that you too can have your own fresh sour cream on hand.
Let me tell you, too, that Bold Bakers have been asking me about Homemade Sour Cream for quite some time. Whether it’s because it’s unavailable in your region, or maybe you’re looking for an inexpensive way to get it, here it is!
And it’s so simple. You’ll just need:
- 3 Ingredients (Milk, Cream, and Lemon Juice)
- A Jar
That’s it!
How To Make Sour Cream
Before I tried this recipe, I actually had no idea how sour cream was made. Well, it turns out the name says it all because it’s literally preserved soured cream.
Unlike other homemade dairy products, this method for sour cream requires no cooking at all and very little effort. To make my homemade sour cream all you need is a nice clean jar, milk, cream, and fresh lemon juice. Oh, and a little bit of time, because you have to leave it covered on the countertop overnight. Also, make sure to use a breathable cloth (no lids or plastic wrap), as your sour cream will have a more fragrant flavor with exposure to the air. And that’s it!
After combining all of the ingredients, they will do the work for you. The acid in the lemon reacts with the cream, similar to making my Homemade Buttermilk. After a night on the counter, I give the mix a good stir, and BAM, Homemade Sour Cream. The final sour cream is thick, rich, and tangy. There is no difference between this sour cream and the store-bought stuff, making it an amazing recipe to have on hand!

If Your Sour Cream Is Thin
The consistency of your Homemade Sour Cream might be slightly looser than something store-bought, but it will provide all the same flavor and moisture to your baking. The reason for this is that there are no artificial thickeners, or gelling agents, that are often added to commercial brands of sour cream.
What you’re getting is sour cream in its purest form!
The good news is that even though it might be thinner than you’re used to, you won’t be able to tell the difference when using it in your baking. On tacos, though, it just might taste even better than store-bought!
How To Store Sour Cream
Because there is nothing in the sour cream to preserve it, you will want to store it in an airtight container in your fridge. That said, it will last for a good 2 weeks! This rarely lasts that long for me so sometimes I even double down and make a larger batch.
Just make sure it stays refrigerated and you’ll be good to go.
How To Use Sour Cream in Baking
Dairy is a really important ingredient when it comes to baking. It serves many purposes like replacing eggs, making richer cakes, and because it contains acid it tenderizes the gluten so it yields incredibly soft cakes too. This Sour Cream recipe can be used in the place of buttermilk, or even yogurt. One of my favorite ways to use it in my baking is in my Chocolate Bundt Cake. In this case, my sour cream makes all the difference, adding a very distinct richness and moist texture.
