Why you’ll love this buttercream:

So, you love pistachios? Me too!

This light and fluffy pistachio buttercream is crazy easy to make!

And you’ll love the burst of natural pistachio flavors, because we’re using pure pistachio paste to flavor this buttercream!

Plus, this buttercream doesn’t have any food coloring, thanks to the vibrant color of my homemade pistachio paste. (<- Check out the full tutorial for the secret to the vibrant green color!)

Ingredients Notes:

  • Butter – I prefer unsalted butter because that way I’m in control of how much salt goes in to my buttercream frosting. Different brands have different levels of saltiness. Especially, European butters are much saltier than American brands.
  • Pistachio paste – My DIY pistachio paste is quick and easy to make, and that’s what I typically use. Note that most store-bought pistachio paste contains sugar, but it’ll still work in this recipe.
  • Powdered sugar – Since powdered sugar (aka confectioner’s sugar) clumps easily, I highly recommend sifting it for the smoothest buttercream.
  • Salt balances the sweetness, making the icing well balanced!

How to make pistachio buttercream:

  1. Beat butter and pistachio paste until nice and fluffy.
  2. Add powdered sugar along with salt and whip it until the frosting is nice and smooth, about 2 more minutes.

Seriously, how easy is that??

Tips for Fluffy Buttercream Icing:

  • Room temperature butter is essential for making a fluffy buttercream. Leave butter out on the counter for about 1 hour prior to making the frosting.
  • Beat butter and pistachio paste until fluffy and doubled in volume. And only then add powdered sugar.

Tip

The proper butter consistency is important. You don’t want too soft, or too hard butter to make buttercream frosting. Here’s what room temperature butter means.

How to store buttercream:

  • Refrigerate the buttercream frosting in an airtight container for up to 1 week.
  • Or freeze it for up to 3 months.
  • Thaw the frozen buttercream in the fridge overnight. Bring it to room temperature and whip it again in the mixer until fluffy.

Ways to use pistachio buttercream:

This buttercream is quite versatile. It complements just about anything. Here’re a few ideas for you:

Enjoy!

    I made this today but when I blended my pistachios I struggled to get the smooth consistently you did. It still had chunks. I added more water. The result was my icing was a little runny.

    I also found the icing was a bit too buttety for my liking. I would probably change it 3/4 cup next time.

    Thanks for the recipe!!

    1. Hi, Daveenah. What kind of pistachio paste did you use? If you used a chunky paste, there’s nothing you can do to turn it into a smooth buttercream. And no, adding water won’t help at all, and it’ll just make the buttercream runny, as you had experienced. So, I’d advice to use a good pistachio paste to begin with. If you’re making it yourself, process it in the food processor really well. And if you want less butter-y buttercream, you can add more powdered sugar. Thanks for trying my recipe and reaching out!!

  2. Hello, the recipe looks great. If I put it over cupcakes, how long do you think it will last without a fridge? or will it melt? 

    1. Hi, Gina. It should be fine fore few hours. This buttercream won’t melt unless it’s in hot environment for too long.

  3. I don’t have the Pistachio paste but I’ve got pistachio flavoring, will this recipe still work with the Pistachio flavoring?

    1. Hi, Jamie. Not sure what kind of pistachio flavoring you have, but I haven’t tested this recipe with anything but pistachio paste.

    This is possibly the best buttercream I’ve ever tasted. The homemade pistachio butter absolutely seals the deal. Used it as a macaron filling and it was a hit with everyone. Thanks so much!!!

    This Buttercream recipe is perfect!  I followed it as written.  Now I practice self-control, trying not to eat the whole cake before anyone sees it. 

  6. I have used this recipe several times now. Love it! The only thing I add, is a 1/4 tsp almond extract. It just enhances the flavor of the pistachio, that much more!
