This Russian buttercream is made with just 4 ingredients!! It's secret ingredient is sweetened condensed milk, which gives it a silky smooth consistency
- 1 cup unsalted butter, room temperature
- 1 tsp vanilla extract
- ¼ tsp of salt
- 1 14 oz can sweetened condensed milk
- Powdered sugar
Whip the room temperature unsalted butter on a medium high speed with a whisk attachment of a stand mixer or hand mixer for 5-7 minutes. The butter should lighten in color as you incorporate air into it.
Add in the vanilla extract and salt, and mix on a low speed until incorporated.
Slowly mix in the sweetened condensed milk, adding ¼ of the can at a time, mixing on a medium speed.
Scrape down the sides and bottom of the bowl with a rubber spatula throughout the process. The sweetened condensed milk sometimes pools at the bottom of the bowl, so be sure to scrape all the way to the bottom.
If you frosting is broken or not stiff enough, you can add in powdered sugar, 1/2 cup at a time to thicken it and bring it together.
Use to frost layer cakes, pipe on cupcakes, or even to ice cookie. It tastes amazing on just about everything!!
