Making Stable Buttercream
A reliable buttercream is the backbone of any cake work. This version uses a basic American approach that avoids the instability of whipped fats, ensuring you can pipe sharp edges that hold their shape.
Temperature is your only variable
If your butter is too warm, the emulsion breaks and turns into a soup. If it is too cold, the sugar will not incorporate properly.
- Stand mixer with paddle attachment
- Large mixing bowl
- Rubber spatula
What goes in.
- 1 lbunsalted butter, softened to 65°F
- 4 cupspowdered sugar, sifted
- 2 tbspheavy cream
- 1 tspvanilla extract
- 1 pinchfine sea salt
Beating to Aeration
You are not just mixing; you are forcing air into the fat cells. Beat the butter alone until it shifts from yellow to ivory white before adding any sugar.
The method.
Cream the butter
Place the butter in the mixer on medium-high speed. Beat for 5 full minutes until the texture is light, fluffy, and significantly paler than when you started.
Incorporate sugar
Turn the mixer to the lowest setting. Add the powdered sugar one cup at a time. Wait for each cup to vanish into the butter before adding the next to avoid a cloud of dust.
Adjust consistency
Add the heavy cream, vanilla, and salt. Increase the speed to medium and beat for another 3 minutes. The buttercream should look smooth and hold a firm peak on the end of a spatula.
Remove air bubbles
Switch to the paddle attachment or use a spatula to stir the buttercream by hand in a circular motion for 1 minute. This pops the large air bubbles, creating a dense, professional finish.
Other turns to take.
Chocolate
Sift 1/2 cup of high-quality cocoa powder into the sugar before adding to the butter.
Brown Butter
Brown the butter in a pan first, then chill it until it returns to a solid, spreadable consistency before beginning step one.
When it doesn't go to plan.
Always sift your powdered sugar to avoid lumps that will clog your piping tips.
If the mixture looks curdled, the butter was likely too cold; keep beating, the friction will warm it up.
If the mixture is sliding off the cake, place the bowl in the fridge for 10 minutes and whip again.

Can I use salted butter?
You can, but the salt content varies by brand. If you use it, omit the additional pinch of salt to keep control over the final flavor.
How long can I store this?
It stays good in an airtight container at room temperature for two days, or in the refrigerator for two weeks. If refrigerated, let it come to room temperature and re-whip before use.
