1. Use the right powdered sugar the right way.
Use 10x finely ground powdered sugar for the silkiest smoothest buttercream. On the package of powdered sugar it often says how finely ground it is. 10x is the finest, and what you want to use in any type of frosting. 5x is more coarse, and is what you’d want to use if you’re sprinkling powdered sugar onto something as a garnish and don’t want it to melt into the food.
The right way to use powdered sugar is to ALWAYS sift it before adding it into your buttercream. Most recipes are written like this, “3 cups powdered sugar, sifted.” Which means you measure the sugar first THEN sift it before adding it in.
2. Beat, beat, beat the butter!
For buttercream that’s so velvety smooth it melts in your mouth, don’t rush beating the butter. First, start with cool room temperature butter. You don’t want it to be so warm that it’s greasy. Use an electric mixer, either hand held or standing, and beat it with the sugar until combined. Then increase the speed to medium and beat until it lightens in color and looks fluffy in texture. Give it a taste, it should melt on your tongue and not feel heavy or dense in the slightest. This will take about 3 to 4 minutes of beating.
3. You can use cream OR milk, just use the right amount.
Although it’s called buttercream, you can usually get away with using milk instead of cream if your recipe calls for it. The milk will be a little less rich and creamy, but should still work.
4. Adjust the sugar to your preference.
Add the sugar in gradually, and taste it as you go. I personally prefer my buttercream a little less sweet. So I might cut half the liquid in the recipe, or omit it altogether, in order to reduce the sugar. This will allow me to keep the same consistency without adding in so much sugar that it’s all you taste.
5. Never add too much liquid to your buttercream.
Adding additional liquid to your buttercream, such as flavorings or purees, can make it far too liquidy to come together nicely. And you don’t want to have to add a bunch of powdered sugar to thicken it up, because then it will be far too sweet. So add flavors with potent extracts, jams, or non-liquid ingredients.
This can go for food coloring as well. Gel food coloring allows for vibrant colors without adding too much extra liquid.

6. Prevent your buttercream from melting on a hot or humid day.
If you’re making a cake or cupcakes for a party or picnic that’s outside, or it’s a particularly hot or humid day, the last thing you want is melted messy buttercream. Especially if you went to the trouble of decorating with it. What I like to do is store the cake or cupcake the fridge just until you set up for the party or picnic. By the time everyone is ready for cake later in the afternoon, it should be the perfect temperature without running the risk of melting.
You can also use half shortening in your buttercream to make it more stable and less likely to melt. Check out this post the differences between butter and shortening, and why I usually opt for butter.
BONUS TIP: Make your buttercream ahead of time
Buttercream can be made ahead of time and stored in an airtight container in the fridge for 1 week, or in the freezer for 3 months. Let it come to room temperature then re-whip with an electric mixer until light and fluffy again.
