Give your baked goods a rich, silky glow-up with this quick and easy recipe for frosting that drizzles and spreads like a dream!
I love cake. But it’s really just a delivery system for frosting. That fluffy layer of sweetness takes an already great dessert to the next level of deliciousness. My go-to choice used to be buttercream, but sometimes that icing is just too cloyingly sweet.
Enter this sour cream frosting recipe. It’s the glow-up your desserts never saw coming! I mean, sour cream isn’t an ingredient most of us associate with sweets. But it brings umami depth and a bit of tang to the flavor profile of this icing, the way adding a dash of sea salt enhances the richness of caramel or dark chocolate. Then vanilla extract brings in a creamy note to balance everything out.
Plus, the combo of sour cream and butter in this recipe delivers a silky texture you cannot get with, say, cream cheese. Simply adjust the amount of powdered sugar to get the exact consistency you prefer, depending on whether you plan to spread or drizzle it.
And because it takes just 10 minutes, this frosting is perfect for home baking. Use it on cakes, cupcakes, cookies, cinnamon rolls—anything that could use a little something extra. You can even add a couple drops of food coloring for a festive touch!
Handling the heat: sour cream vs. buttercream frosting
This sour cream frosting can handle the heat better than buttercream. So if your goal is drizzling over hot cinnamon rolls, this recipe is your hands-down go-to! Why? Sour cream frosting has more moisture and slightly less fat than straight buttercream, which makes it naturally softer and more pourable at room temperature. When heated by freshly baked rolls or pastries, it becomes even more fluid, allowing you to spoon or drizzle it over warm treats without it instantly sliding off or separating.
Additionally, the tangy, cultured base of sour cream helps the frosting maintain a creamy, glossy texture—rather than melting into grease puddles or seeping away—because the combination of acid and sugar creates a smooth emulsion that stays stable atop warm surfaces for a longer window. It will still slowly soften as it warms, but it coats pastries in a decadent, slightly set layer that soaks into the cracks and crevices, rather than pooling at the bottom.
How do I store leftovers?
Refrigerate leftover sour cream frosting within 2 hours of mixing it to prevent spoilage. It’ll keep in an airtight container in the fridge for up to 3 days. When you’re ready to use it, let it sit at room temp for 15–30 minutes, then whip or stir gently to restore its creamy texture.
Freezing is possible but not ideal, as the combination of butter and sour cream can separate once thawed. However, if you need the longer storage time, place the frosting in a freezer-safe airtight container, press a piece of plastic wrap against the surface, and freeze for up to 1 month. Thaw overnight in the fridge and beat briefly before using to smooth out the texture.
Serving suggestions
Serve your sour cream frosting atop a wide array of baked goods. If you’re not into mascarpone, sub it in for the frosting on this Creamsicle Cake for a lighter yet still dreamy version. Slather it on The Best Homemade Cinnamon Rolls while they’re still hot, or use it to elevate these Simple Vanilla Cupcakes. Let guests help themselves to a side of this frosting for slices of Spiced Applesauce Bread or Delicious Coffee Cake, paired with strong coffee.
Sour Cream Frosting
Ingredients
- 1/2 cup unsalted butter softened to room temperature
- 1/4 cup sour cream warmed to room temperature
- 1 teaspoon pure vanilla extract
- 3 to 4 cups powdered sugar sifted
Instructions
- In a large mixing bowl or stand mixer fitted with the paddle attachment, beat the butter on medium speed for 2–3 minutes until it’s light and fluffy.
- Add the sour cream and vanilla extract. Beat on medium speed just until combined and creamy.
- Reduce the mixer speed to low and gradually add the sifted powdered sugar, 1/2 cup at a time. Scrape down the sides of the bowl as needed.
- Once the sugar is incorporated, increase the speed to medium and beat for 1–2 minutes until the frosting is smooth and fluffy. If the frosting seems too thick, blend in 1 tablespoon of sour cream (or milk) at a time until spreadable. If it’s too thin, add more powdered sugar, 1/4 cup at a time, until you reach the right consistency.
- Use immediately to frost cakes, cupcakes, or cookies.
