This super creamy Russian Buttercream comes together in about 10 minutes and requires just a few ingredients for a quick and easy frosting that your family will love!

It’s perfect for decorating cakes, cupcakes, or just indulging with a spoon (no judgment!).
Ingredients for Russian Buttercream
1 cup unsalted butter, softened
Butter is going to give you the best flavor and texture for this frosting. I prefer unsalted butter so that I can control the sodium level myself. This helps ensure that the sweetness from the sugar shines through without being overly salty. If you’re in a pinch, you can substitute with margarine, but you’ll lose that rich, buttery taste that makes this frosting shine. The butter should be softened and at room temperature, this means you’ll want to set it out about 30-60 minutes before you start for the best results!
1 can (14 oz) sweetened condensed milk
This is the secret ingredient that makes Russian Buttercream so unique and delicious! The sweetened condensed milk adds an ultra-creamy texture and sweetness that traditional buttercream just can’t compete with. If you’re looking for alternatives, you might be able to use evaporated milk with added sugar, but honestly just go for the condensed milk. It’ll work wonders here!
Optional flavorings (vanilla extract, cocoa powder, or coffee)
While the basic buttercream is mouth-wateringly good on its own, you can easily customize it! A couple of teaspoons of vanilla extract elevates the flavor to a whole new level, turning your buttercream into a dreamy experience. Feeling adventurous? Add a tablespoon of cocoa powder for a chocolate version, or a teaspoon of coffee for a delicious mocha twist. Fresh or frozen flavorings work well; you can even toss in some almond extract if you’re feeling fancy.

How to Make Russian Buttercream
1. Beat the Butter
In a large mixing bowl, combine the softened butter and sweetened condensed milk. Using an electric mixer, beat on medium speed for about 5-7 minutes until the mixture is fluffy and light, as light as a cloud! You’ll want to scrape down the sides of the bowl every now and then to make sure everything is incorporated. Just think, fluffy buttercream, how can you say no?
2. Flavor It Up
This is where the fun starts! Now, if you’re adding in optional flavorings, sprinkle in your extras: maybe a splash of vanilla or that chocolate powder. Turn your mixer back on and give it a good mix for another minute or two, just until it’s completely combined.
3. Use or Store
You can use the buttercream immediately frost that cake, cupcake, or even dip some fruit in it, but if you want to make it ahead of time, store it in an airtight container in the fridge. Just remember to whip it again for about a minute before using to get that lovely fluffy texture back!
4. Enjoy!
Now, spread this beautiful buttercream like it’s nobody’s business. And trust me, it’s hard not to lick the bowl clean. Who could resist?
