Vanilla Buttercream may seem beyond simple but I get a surprising number of questions from home bakers everywhere. So let’s set the record straight with perhaps the most ubiquitous and variable frosting there is! Let me know how you enjoy this recipe; historically, I have found it to be a crowd pleaser.

Is buttercream or whipped frosting better?

The main difference between buttercream and whipped frosting is butter. Whipped frosting does not contain butter and is a lighter and fluffier icing. Buttercream contains a good amount of butter and has more of a rich flavor; so you be the judge! 🙂

Will buttercream melt at room temperature?

When buttercream is left out at room temperature, it will form sort of a crust on the outer layer while the inside will stay fairly smooth. If it is very warm or humid, the buttercream can loose structure. This will affect decorations you’ve pipes and may even destabilize layer cakes, causing them to sag or collapse.

How long can you leave out buttercream frosting?

You can leave out buttercream frosting for overnight if covered. If the buttercream contains cream cheese, then it should always be refrigerated for it to remain safe to eat. Buttercream that contains dairy will spoil more quickly so should be refrigerated after a few hours.

How do I thin out buttercream frosting?

If you want to thin out buttercream frosting, you’ll want to add in some extra cream or milk. I recommend mixing in a tablespoon at a time until the desired consistency is reached.

Using room temperature butter is the most important thing to do when whipping up a batch of “buttercream.” If you’re looking for a very spreadable and very smooth icing, you can add the full amount of cream in (and maybe even a bit more).

You can always substitute a fruit puree, reduction or liqueur if you wanted to spice things up, by the way. If you are doing some detailed work — like piping roses, for example — you’ll be using MUCH LESS cream.

Some people prefer the all-white buttercream that uses vanilla extract. Some people love seeing little vanilla seeds scattered throughout. If you do want to use a vanilla bean, simply split along the middle — scrape out the seeds with a knife — and allow to defuse in the cream that you’re using (or you could even add some bourbon).

For people who live in very warm climates, substituting in some vegetable shortening for the butter will help keep your confections stable. As a final note, I would always remember to sift your powdered sugar as you will never know when a clump will come back to haunt you.

Make sure to sift your powdered sugar, especially if you’re going to be using any piping tips. Those clumps will cause clogs that make decorating nearly impossible!

Steps To Make This Buttercream Frosting

How Do You Make Buttercream Frosting?

Cream the butter in a standing mixer for about 5 minutes using a paddle attachment.
Sift the confectioners sugar and slowly beat it in, in multiple batches.
Once incorporated, with the mixer running on low, you can go ahead and add the vanilla extract.
While the mixer is running on low, add in the three tablespoons of heavy whipping cream.
When your buttercream is finished, you should have a nice even and fluffy consistency.
You can place it in a piping bag, snip the tip off, and you’re ready to go!
