Add the softened Country Crock Plant Butter to the bowl of a stand mixer fitted with the paddle attachment.
Whip on medium high speed for 20 full minutes. This step is very important, even if it looks ready sooner.
Slowly add the powdered sugar to the whipped butter.
Add the vanilla extract and dairy-free milk.
Continue whipping for another 4–5 minutes, scrape down the sides of the bowl as needed, until the frosting is fully incorporated, light, and smooth with no grainy texture.
Pipe onto your cakes, cupcakes or whatever dessert you're making.
You can make this buttercream in advance and store it in the fridge for a couple days or in the freezer for 3 months.
