A sweet and tangy topping for all of your favorite sweet treats! My Sour Cream Frosting comes together in minutes with a few simple ingredients. Enjoy this luscious spread with baked goods or fresh fruit!
Silky smooth and not too sweet, you’ll want to spread this sour cream icing on everything in sight.
The best part? My recipe uses just 5 ingredients that you may already have at home! Start with whipped butter, then add vanilla extract, powdered sugar, and a touch of fresh lemon juice to the star of the show.
I like to toss everything into my stand mixer, but you could use an electric hand mixer and a large bowl if needed. It’s so simple, even kids or grandkids could help!
This easy sour cream frosting is sure to become a staple in your recipe collection. Be sure to add my recipes for royal icing and fresh cherry buttercream as well.
Key ingredients & substitutions for Sour Cream Frosting
- Butter — Always using unsalted for frostings and spreads! Each brand of butter contains a different amount of salt, so it’s better to add it yourself as needed.
- Sour cream — The star of this recipe! For the best consistency, use a full-fat variety. Lighter versions have extra water, which will create a runnier consistency.
- Lemon juice — This is optional, but I highly recommend it! Along with the sour cream, it gives the frosting just the right amount of tanginess — tastes just like cream cheese frosting!
- Vanilla extract — Adds warmth and a touch of caramel sweetness. If you prefer your icing to not be too yellow, use clear vanilla instead.
- Powdered sugar — Be sure to sift well before adding to your mixer. This is notorious for having tiny little clumps that aren’t easily broken up with a whisk or when blended.
How to Make Sour Cream Icing
Bring the butter and sour cream to room temperature before starting the recipe. You’ll get smoother results, and the mixture will come together much faster.
STEP 1 | Whip the butter
Add the softened stick to a stand mixer and beat for several minutes. It should lighten in color to a very pale yellow and have a fluffy, airy texture.
STEP 2 | Add the remaining ingredients
Starting on low, incorporate the sour cream, lemon juice, and vanilla (plus a pinch of salt) until well blended. Then, mix in the powdered sugar a few spoonfuls at a time.
Once it has all been added, scrape down the bowl and whip on medium until creamy — it should take less than a minute.
STEP 3 | Decorate your goodies
Spread onto baked goods using an offset spatula or knife, or transfer the icing to a piping bag fitted with a decorating tip.
tips
- If the sour cream frosting is runny, add more powdered sugar — a couple of tablespoons at a time — until the desired consistency is reached.
- Alternatively, adding 1 to 2 tablespoons of heavy cream (or even water) will thin out icing that is too thick.
- For a chocolate version, omit the lemon juice and mix in 1-2 tablespoons of unsweetened cocoa powder with the sugar.
Frequently asked questions
There are several reasons, actually! First, it helps prevent that cloying, “hurts your teeth” sweetness that can occur in simple buttercreams. It also enhances the added flavors — in this case, vanilla and lemon.
Yes! While whipped butter is stable at room temperature, the addition of other dairy ingredients requires it to be chilled. Keep well covered or in an airtight container for up to 5 days and re-whip for a minute or two before using.
Technically, yes, but the consistency can get tricky. You could substitute margarine, shortening, or a combination of both if you prefer.
Also, keep in mind that the flavor may be slightly different and icings tend to be sweeter when made with shortening. Give it a taste and blend in an extra pinch of salt if needed.
Serving suggestions
Spread this delicious sour cream icing over cupcakes, cookies, brownies, and more! It would even be delicious as a sweet dip for fresh berries and fruit or spooned into the center of whoopie pies.
You can also add a drop or two of food coloring (the gel kind works best) to match any holiday or special occasion. If you’ll be making this ahead of time, know that the color will continue to deepen the longer it sits.
