This rich and velvety Chocolate Buttercream Frosting is impossible to beat. It is so simple to make and perfectly balanced without being overly sweet. Make it in just about 5 minutes, and use it to frost all of your favorite treats.
In the bowl of a stand mixer with a whisk attachment, add the softened butter, cocoa, room-temperature heavy cream, vanilla extract, and sea salt. Add ⅓ of the powdered sugar (about 1 cup) to the bowl and begin to whip together. Use a low speed at first and increase slowly. Once the powdered sugar is worked in, add the remaining powdered sugar 1 cup at a time, scraping the sides of the bowl with a rubber spatula as needed. Mix until a smooth consistency is achieved. Taste the frosting and adjust the sweetness or salt if needed.
Store leftover frosting in an airtight container in the fridge for up to 1 week. Before use, allow frosting to come to room temperature and return it to the stand mixer to whip on medium speed until smooth.
Notes

Use fully softened butter and room-temperature heavy cream to result in a smooth and decadent frosting.
If your powdered sugar has lumps, sift it before use.
Use unsalted butter if you are sensitive to salt.
If you soften the butter overnight and it is still pretty firm, there are a few things you can do to soften it without melting it. First, I like to place the butter on the stovetop (stove is off) of a preheating oven. I rotate the sticks of butter periodically to aid the softening. Then I will take the butter and place the butter alone in the stand mixer and whip it until it is smooth. Once the butter is smooth, I proceed with the recipe.
Add the powdered sugar 1 cup at a time to avoid making a huge mess. Using the shield that comes with your Kitchenaid is also helpful.
Leftover chocolate buttercream frosting can be stored in an airtight container in the fridge for up to 1 week. Just allow it to come to room temperature before using. You can whip it again if needed.
