Please go and have a read of my Buttercream Icing FAQ which answers a lot of the questions about this recipe asked in the hundreds of comments on this post below!

How do you make buttercream frosting?

There are four basic ingredients for this buttercream frosting and I have kept it simple and straightforward for years now:

  1. One cup of salted butter
  2. Three teaspoons of vanilla
  3. Four cups of icing sugar
  4. Four to five tablespoons of  coffee cream (18% and up)

Commonly Asked Buttercream Frosting Questions and Answers

Do I have to refrigerate a cake with buttercream frosting?

This buttercream has butter and it has whipping cream in it. I personally leave it out all day and it’s fine ( butter is always fine at room temperature) but the whipping cream? That’s a personal call for you. I have left it out overnight, but I honestly have to tell you to refrigerate it instead of leaving it out. But it’s really a personal decision. Apparently because of all the sugar you can leave a cake with buttercream frosting out for 2-3 days.

How long can you leave a cake with buttercream frosting out?

I leave mine out for a day, not in the hot sun at all and it’s fine. According to the US food and inspection agency, you can leave a cake with buttercream frosting out for 2-3 days.

What is the best butter to use for buttercream frosting?

Salted and organic butter is literally the best butter that you an use in a buttercream frosting. It is the salt that really makes this the best buttercream frosting ever. It’s actually a myth that salted butter is an inferior quality – it’s not. It’s the same quality.

How do I make buttercream frosting stiffer?

You will want to use less cream in order to make the frosting stiffer. Start out with only a small amount of cream and add it until you get the consistency that you want.

How do you thicken up buttercream frosting?

This buttercream frosting is thick to start without adding in the cream! To start, beat in the icing sugar and see what the thickness of the frosting is. Then you can add a little bit of cream, a little at a time, until you reach the desired consistency. IF you go too far, you then can add more icing sugar/powdered sugar to thicken it back up.

How do you soften buttercream icing?

This one is easy, leave it out on the counter at room temperature for 45-60 minutes and it will be soft! If that doesn’t work and your frosting is too thick, then you might have to beat it again and add some more cream.

Can you store buttercream frosting in the refrigerator?

You bet! Buttercream frosting/icing can be stored in the refrigerator for a week or two, as long as the whipping cream that you use wasn’t going to expire soon.

Can you freeze buttercream frosting?

I freeze it all the time! Simply defrost, mix and use as normal.

Tips and Tricks for the Best Buttercream Frosting

  • Always use salted butter. When I first wrote this recipe in 2010 there weren’t many people that were food blogging compared to today, so I literally couldn’t find a SINGLE buttercream frosting recipe on the internet that used salted butter! Now I am sure that if I looked there would be tons of recipes similar to this one.  Oh, how times have changed! So I had discovered that salt and sweet are a match made in heaven for icing and I never looked back. You can also read about the difference between salted and unsalted butter.
  • Whip that butter, with a paddle beater if you have it, if not, don’t worry. You can also use the beaters on your handheld mixer just fine to beat the buttercream frosting! You want the butter to be smooth and creamy before you add the icing sugar.
  • Fresh icing sugar makes all the difference. Icing sugar/powdered sugar/confectioners sugar goes stale, and you can sure taste it when it does! Crack open a fresh bag for icings, you won’t be sorry! Over the years many people have agreed that this is another trick to making great buttercream frosting.
  • You can make this frosting as light or as heavy as you want by adjusting the amount of heavy cream that you use.
  • Read this if you are looking for piping techniques.

Ingredients
  • 1 cup of salted butter
  • 3 teaspoons of vanilla
  • 4 cups of icing sugar
  • 4-5 tablespoons of coffee cream 18% and up
Instructions
  1. Get out the salted butter! Trust me and use salted butter, it's the secret ingredient!

  2. Beat the butter until it is light and creamy. This is important as you are adding the icing sugar next. If the butter isn't creamy you can get lumps in the icing.

  3. Add in the icing sugar. Again, if you are like me and can taste stale icing sugar, you will need a fresh bag.

  4. Add in the cream.. I used 4 tablespoons for my preference, you adjust to what you want.

  5. Stiffer icing = less cream. Lighter icing = more cream. Adjust the amount to your liking by adding one tablespoon at a time until the desired consistency is reached.

  6. Add the vanilla then keep mixing it until fluffy and thoroughly combined.

Recipe Notes

Using salted butter instead of adding a dash of salt ensures that you have salt added throughout the frosting.

If you want low sodium, take out the salted butter and use unsalted.

This frosting freezes very well! You can ice a cake and freeze it, or simply freeze your leftovers to use another day.

If you are making a 9x13 cake, double the recipe.

I find I can cover 16 cupcakes with one batch. How many you can ice depends on how thick you slather the icing on!

    I found the original recipe, as is, to taste too much like butter. Adding some almond extract in place of one of the tsp of vanilla seemed to solve this problem. Delicious! I also found whipping it longer made it whiter and fluffier.
