Silky smooth and luxuriously light, this pistachio cream filling is simply divine! Though it requires an advance technique, this pistachio cream is so worth the effort. It’s a perfect filling for pistachio macarons, but it also pipes beautifully on cupcakes and cakes!

I think I’ve mentioned one too many times that I’m not really a big fan of classic American buttercream with powdered sugar. That’s why I don’t hesitate to take an extra step to make a batch of Swiss Meringue buttercream. Or if I’m short on time, my go-to frosting is this easy cream cheese frosting.

And today I’m going to share with you another wonderful buttercream recipe that you’ll fall in love from first bite.

Ready to expand your buttercream experience?

Meet silky smooth, luxuriously light French buttercream. And with pistachio paste, this pistachio cream becomes an ultimate frosting/filling of all times!

WHAT IS THE DIFFERENCE BETWEEN FRENCH BUTTERCREAM AND SWISS BUTTERCREAM?

Swiss (or Italian) meringue buttercream recipes are based on meringue made with egg whites and sugar syrup. French buttercream, on other hand, is made with egg yolks and sugar syrup, and then butter added into the mix later.

Frankly, this is not a simple recipe, in fact it requires an advanced technique: sugar syrup! BUT it’s totally worth the effort. This pistachio cream is rich and luxuriously creamy.

Since the original recipe makes bigger batch than I need for my basic macaron shells recipe, I adapted the amounts to make just enough filling for my macaron recipe. But if you need more filling for cupcakes, for example, feel free to double the recipe.

As I mentioned above, this recipe requires an advance technique and precision for success! But equipped with proper tools and constant attention, this pistachio cream filling comes together quite quickly.

FRENCH BUTTERCREAM SUCCESS TIPS:

  • Make sure to cook the sugar syrup to proper temperature. Cook it too short and your buttercream won’t set properly. Cook it for too long and you’ll end up with a rock sugar instead of buttercream. Sugar syrup should reach firm ball stage, which is 245-250°F. And make sure it doesn’t go over 250°F, or it’ll start turning amber color.
  • It’s best if your mixer is placed near the stove, as you’ll work simultaneously on cooking the syrup to correct temperature and whipping the egg yolks.
  • Stand mixer is highly recommended. It’s much easier to work with stand mixer, because we need to pour hot sugar syrup into whipped egg yolks very slowly while the mixer is running!
  • It’s important to pour the sugar syrup in a very thin stream. If poured too much, sugar syrup hardens as it hits the bowl and turns into a rock candy.
  • Soften the butter to room temperature. It shouldn’t be too soft, or about to melt. Here’s what room temperature butter means.

Remember, speed and attention is key to success.

And now, here are step by step photos to guide you through the process.

For accuracy, use a candy or any thermometer to monitor the temperature of the sugar syrup.

Whip the egg yolks until it’s doubled in size and tuns into pale yellow mixture.

Be very careful when you pour hot syrup into the beating egg yolks. Decrease the speed to medium low, and pour into the side of the bowl, instead of whisk, to prevent splattering. And remember, very thin stream, especially in the beginning!

Once all the syrup poured in, increase the speed and whip until the mixture is cooled down. And then add butter a little bit at a time.

If you add the butter into too warm mixture, your filling will turn into a soup, because butter will melt.

Also, let me share couple tips to get that beautiful vibrant green color.

  1. Use quality pistachio paste. I know, it’s not cheap. But you can save some $$ if you  make this simple homemade pistachio paste.
  2. Add a tiny bit of food coloring. I use this gel food coloring from AmeriColor.

TROUBLESHOOTING COMMON ISSUES:

Issue: The sugar syrup turned into rock candy when poured into egg yolks.

Fix:

  1. Make sure the sugar syrup wasn’t over-cooked, meaning it didn’t go over 250°F. When in doubt, remove from heat when it reaches 245°F. And immediately pour it into the egg yolks.
  2. Make sure to pour sugar syrup in a very thin stream, especially at the beginning.
  3. Make sure egg yolks are at room temperature and whipped till light pale.

Issue: My French buttercream is too runny.

Fix:

  1. Make sure to cook the sugar syrup reaches at least 245°F (118°C). If it doesn’t reach firm-ball stage, buttercream won’t set properly.
  2. Make sure to whip the egg yolks with sugar syrup until it reaches at least 104°F (40°C) before adding butter. If the mixture is too hot, butter melts and creates a runny buttercream.

Pistachio Cream Filling

This pistachio cream filling is silky smooth and luxurious! It's subtly sweet and ultra-creamy. It's a perfect filling for French macarons but pipes beautifully on cupcakes and cakes too.

Ingredients

  • 1/3 cup (65g) granuated sugar
  • 2 tablespoons (30ml) water
  • 2 egg yolks at room tempeature
  • 2 oz (55g) unsalted butter softened
  • 3 teaspoons (20g) pure pistachio paste (I used my homemade version)
Note: I test all my recipes with both measurements for the most precise and accurate result!

Instructions

  • In a small saucepan, combine sugar and water. Bring it to a boil over medium heat, stirring it constantly until sugar is completely dissolved. Then continue to cook until the syrup reaches 250°F (120°C), about 5 minutes.
  • Simultaneously, start beating egg yolks in a mixing bowl with whisk attachment until it’s doubled in size and becomes pale in color, about 2 minutes.
  • While the mixer is running on low speed, slowly pour the hot syrup into the egg yolks. Pour the syrup into the side of the bowl, instead of the whisk, so that it doesn’t splatter.
  • Increase the speed to medium high, and beat the mixture until it cools down to 104°F (40°C). The mixture will become smooth and white.
  • Stir in butter one tablespoon at a time.
  • Then add pistachio paste and food coloring, if desired. Continue to beat the cream until nice and smooth.

    This is the best buttercream I’ve ever had! I used it to fill the pistachio macarons I made using your recipe. It was my first time making macarons and they turned out to be the best I’ve ever had as well! Thank you so much for sharing your recipes and for making them so easy to follow!!!
    Now I want to try this buttercream for a cake. I’ll probably end up trying it on just about everything eventually.
    This was my first time making french buttercream and I was wondering: Does it freeze well like Swiss and Italian meringue buttercreams? Just in case I accidentally or intentionally make more than I need for the cake.
    Thank you, in advance, for any assistance you can offer me.

    Fantastic buttercream! Love the richness and smoothness of it….and of course the taste. But since I live in Australia where is hot and humid, I noticed that the buttercream does not mantain its firmness when I use it to fill macarons. Could I add some cornstarch to it to stabilise it a bit more in the scorching Aussie summer?

    Hi!

    I made this and it was amazing. Just wanted to double check – you wrote 4 oz of butter but 55g, but isn’t 4 oz butter around 110g? I used 110g.

    Thanks!

      Hi AT. OMG, good catch!!! Thank you so much for letting know. I use 55g of butter, so 2oz. But I’m sure your turned out just fine with a little more butter. Ugh, I feel so bad for my mistake and I can’t thank you enough for your comment.

    If you are making Macarons then you must make this filling – the perfect way to use up those left over egg yolks and makes the Macarons twice a good!! (And even more all the effort😅😅)

    Please include in the ingredients list that the eggs have to be room temperature. I didn’t see that until reading the troubleshoot part and am now unsure if my cream is safe to eat as my eggs were cold. My syrup didn’t turn into rock candy though… please help

      Hi, Valeriya. Your buttercream is safe to eat. Egg yolks would have come to room temperature while it’s beating. And especially since your syrup didn’t turn into rock candy, it indicates that there was no big temperature shock.

    Wow this recipe was phenomenal. Thank you! Perfect for my pistachio macs. Instructions were spot on and clear and I got the result in the picture. I always use salted butter though. Preference. I think it was room temp by the time I incorporated and it was still perfect.

    Hi Shinee,

    Thank so much for this delicious recipe! What is the correct consistency for the resulting cream? I piped this onto a few macarons but even after putting them in the freezer overnight, the filling never solidified. And if I brought them out to room temp, the filling would likely melt. I suspect my pistachio cream filling is more liquid than yours.

    Thanks!
    Mel

      Hi, Mel. I’d say this buttercream is slightly on the softer side, but it definitely hardens when frozen. Did you bring your sugar syrup to 250°F?

        Hi Shinee. I’ve made this recipe twice. The first time I did not reach 250°F, and so I figured I didn’t evaporate enough of the water in the sugar syrup. The 2nd time, I made sure to reach 250°F (I used my thermoworks mk4 to measure) before pouring into the bowl with the whipped egg yolks. This time I got a thicker consistency but it still didn’t solidify in the freezer. Do you recommend using a special kind of butter? I’m using regular unsalted butter.

          Hi, Mel. I don’t use any special butter. Land O Lake’s unsalted butter is my go-to.

    Hi, 

    I was wondering if I can make the pistachio fillings the day before I use it in my macaroons. And if so, do I need to take out of the fridge the next day and let it get to room temp before filling. 

    Thank you for all your helpful tips and recipes.

      Hi, Jana. Yes, you will need to bring it to room temperature, otherwise it’ll be on a firm side. And you may also need to give it a quick whip to make it fluffy. Hope you’ll love them. Let me know how they turn out.

    Hi!

    Wondering what commercial brands you’d recommend for pistachio paste? I’m sure home made has just as good a flavor, but I’m worried about any graininess in the buttercream.

    Thanks in advance!

    THIS WAS AMAZING! I didn’t have paste so I used finely ground pistachios. Audience favorite. I plan on applying this dreamy French buttercream base to other flavors.
