Vanilla Buttercream Frosting
This classic American buttercream is creamy, sweet, and pipes beautifully onto cakes, cupcakes, and cookies alike. The technique behind it—using truly softened butter and sifting the powdered sugar—separates a silky, bakery-quality frosting from a grainy, stiff one.
Equipment
- Stand mixer or electric hand mixer - Essential for achieving proper fluffiness
- Large mixing bowl - If using a hand mixer
- Fine mesh sifter or sieve - For sifting powdered sugar
- Rubber spatula - For scraping down the bowl
- Measuring cups
- Measuring spoons
- Piping bags and piping tips - Optional, for decorating
- Offset spatula - For spreading
Ingredients
- 1 cup unsalted butter - 227 g / 2 sticks, softened to room temperature
- 3 cups powdered sugar - 360 g, sifted (up to 4 cups / 480 g)
- 3 tablespoons heavy whipping cream - 45 ml, or whole milk for a lighter version (up to 4 tablespoons / 60 ml)
- 2 teaspoons pure vanilla extract - 10 ml
- 0.25 teaspoon fine sea salt - 1.5 g
Instructions
- Remove the butter from the refrigerator 1-2 hours ahead of time. It should be soft enough to leave an indent when pressed, but not greasy or melted.
- Place a fine mesh sifter over a large bowl and sift 3-4 cups of powdered sugar in batches, pressing any clumps through with a spoon.
- Place softened butter in a stand mixer fitted with the paddle attachment. Beat on medium-high for 3-5 minutes until pale, fluffy, and almost white in color. Scrape down the bowl once or twice.
- With the mixer on LOW speed, add sifted powdered sugar one cup at a time, allowing 15-20 seconds of incorporation between additions. After all sugar is added, increase to medium and beat for 1 minute. Scrape down the bowl.
- With the mixer on low, add vanilla extract and fine sea salt. Mix on medium speed for 30 seconds until fully combined.
- With the mixer on low, add heavy cream one tablespoon at a time. After each addition, increase to medium and beat for 20-30 seconds. Use 3 tablespoons for spreadable consistency or 2 tablespoons for stiffer piping consistency.
- Increase speed to medium-high and beat for a final 2 minutes until lighter and fluffier. Taste and adjust with more powdered sugar, vanilla, or a pinch of salt as desired. Scrape down the bowl before using or storing.
Notes
- Use real unsalted butter: Margarine or butter substitutes produce a greasy, inferior frosting with a strange aftertaste. Unsalted butter gives you full control over the salt level.
- Never use cold butter: Cold butter will not cream properly no matter how long you mix it, and you'll end up with lumps and a dense, stiff frosting.
- Sift your powdered sugar every time: Powdered sugar clumps during storage, and even small lumps will remain in the finished frosting if you skip sifting.
- Add cream slowly: It's easy to add too much liquid and make the frosting too soft. Add it one tablespoon at a time and check the texture between additions.
- Beat longer than you think you need to: The extended mixing time is what gives the frosting its light, fluffy texture. Don't rush it.
- If your frosting looks curdled, it's usually because the butter was too cold. Keep mixing on medium-high and it will come together.
- If your frosting is too sweet, a small extra pinch of salt or a tiny squeeze of fresh lemon juice will cut through the sweetness beautifully.
- Avoid making frosting in a very humid kitchen. Humidity can make buttercream soft and weepy. If this is unavoidable, use a tiny bit less cream than usual.
- Storage: Store leftover frosting in an airtight container in the refrigerator for up to 2 weeks or freeze for up to 3 months. Bring to room temperature and re-whip before using.
- Flavor variations: Try brown butter, lemon, strawberry, chocolate, almond, salted caramel, or cream cheese variations by adding complementary ingredients to the base recipe.
