Butter should be at room temperature. Beat the butter on high speed for 10 minutes until double in volume. By then it should be airy and fluffy and light in color.

Add sweetened condensed milk and vanilla powder and beat at high again for 10 minutes.

Buttercream frosting is ready.

Apply on the cake and refrigerate it.
