Condensed milk buttercream, also called Russian buttercream, is made with only two ingredients: butter and sweetened condensed milk. It is light, silky, fluffy, incredibly delicious, and pipes beautifully. Most importantly for any home, hobby, or even savvy baker, it is very easy to make.

Guest blogger Sasha Nary, self-taught baker, confectionery artist and a creator of Instagram page @SashaCakesChicago, says that she was practically born eating Russian buttercream from a bottle. So, today she is sharing her best tips and tricks for making it come out perfectly every time.

  • Make sure the butter is soft but not too soft.
    • If the butter is too soft, you may see your Russian buttercream start to separate. Don’t panic! Simply pop your mixer bowl with separated Russian buttercream into the refrigerator for 10 minutes and then re-whip again.
    • If the butter is too cold, this frosting may not whip up all light and fluffy; in that case, just place half of it into a microwave save bowl, warm up for 5-10 seconds, and re-whip with the other half.

  • Whip the butter on high speed for no less than 8 minutes, scraping the side of the bowl every few minutes. That’s how it gets so light and fluffy.
  • Add room temperature sweetened condensed milk carefully in small portions while mixing on medium speed. This prevents the butter and condensed milk mixture from becoming runny and separating.

There are so many possible ways to use this frosting:

Russian buttercream also takes color beautifully – my suggestion is to always use gel food colorings [paid link].

Storing Russian Buttercream

I highly recommend using Russian Buttercream within just few hours of making it. (Since it’s so easy to make, there’s no need to whip up large amounts!)

However, if you do have leftovers or had to make it in advance, store your freshly whipped buttercream in an airtight container, refrigerated for up to 7 days, or frozen for up to 30 days. Let it come to room temperature and then re-whip it before using.


While this recipe is delicious as written, many people add salt, vanilla, or other flavorings to this frosting. It’s a personal preference.

  • 1 cup unsalted butter room temperature
  • 14 ounces sweetened condensed milk room temperature


  • In a bowl of a mixer fitted with a whisk attachment, whip butter until it has tripled in volume and is light and fluffy (approximately 8 minutes). Stop to scrape the bottom of the bowl a few times.
  • Add one third of the sweetened condensed milk while mixing on medium speed. Whip for about 8-10 seconds. Then, stop and scrape down the bowl. Repeat for the next third of the sweetened condensed milk and the final third. Stop mixing 8 seconds after adding the final third. Do not overmix.


It is VERY important to follow the recipe exactly as written. If you don't mix the butter long enough or don't add the sweetened condensed milk while mixing, the frosting may end up separated and too soupy. 
Different brands of sweetened condensed milk are different colors. I've found that Nestle is much lighter than Eagle Brand. Keep this in mind if you prefer a lighter looking frosting.
This recipe frosts 12 cupcakes with a large swirl or 24 cupcakes with a small swirl.
While this recipe is delicious as written, many people add salt, vanilla, or other flavorings to this frosting. It's a personal preference.
