My Quick Vanilla French buttercream is a shortcut version of my traditional French Buttercream. It’s got all the decadence and silky-smooth texture of the original formula, but is made in half the time. Using pasteurized eggs, this recipe is super quick and easy to throw together, making it excellent for those wanting to try a fancier buttercream but are new to baking.

This recipe uses the same ingredients, but except for raw eggs, we’ll use the ones that come in a carton. And there is a brief heating step, but we don't need any thermometers. The purpose is to raise the eggs' temperature just enough to dissolve all the sugar, which is not very high. I love using the microwave for this step because I can make my egg syrup in about 2 minutes. 

And if you’re wondering about the pasteurized eggs, I buy mine at my local supermarket in the egg section. Most of the time, you’ll often see pasteurized egg whites, but if you’re lucky, you’ll have pasteurized whole eggs too! I really do hope you give this recipe a try - it’s a great time saver with all the benefits of a fancy buttercream. If you’ve been meaning to try a French Buttercream but don’t want the hassle of thermometers and water baths like the traditional versions.

Did you know that you can create your own cake recipe with my Quick Vanilla French Buttercream?

I have a tool for you to try called the Cakeculator, which lets you customize cake flavors and pan sizes, and use this frosting to make a custom cake! I will list 1- and 3-cup recipes for this buttercream in the recipe card down below, but you can choose additional frosting quantities with the Cakeculator.

Some ideas to get you started:

Step by step:

Please see my step-by-step guide in the master French Buttercream Guide for now. The steps are similar, except for the heating steps. Because this recipe uses pasteurized eggs (from a carton), there is no need to bring them to 160°F/71°C with a thermometer. In fact, I just use the microwave to heat the eggs with the sugar until everything is smooth and dissolved, then move through the recipe.

Measure by weight, if possible.

Measuring by weight is the best way for you to replicate my recipes. I develop recipes using ingredients (even liquids) measured in grams, which is why you see them listed first in the recipe cards. For measurements under 5 grams, I will typically only list the volumetric measurements (teaspoons, etc.), as most home scales are not precise for such small weights.

In most cases, I have converted grams to volumetric measurements (aka US customary units) for bakers who prefer this method. However, the measurements are not as precise and may have awkward proportions. The recipes should still work, but for the ultimate precision, try to use weight.

This is the OXO scale I use daily. I also purchased this budget version of a good scale, which I keep at my Mom’s house for baking. If you’re interested in other tools I use for my baking, I’ve compiled a list here.

Use room temperature ingredients.

All my ingredients should be used at room temperature, or 65-75 °F/18-24 °C. I will always indicate if you need something outside this range. If no details are given, room temperature is the default. 

Pay attention to the ingredient descriptions.

I try not to be brand-specific, but I will always note an interesting result from a type of ingredient, be it negative or positive. 

A specific note regarding salt: I use Diamond Crystal Kosher salt for everything on this site except for frostings. In frostings, you want the salt to dissolve more easily, and kosher salt tends to leave granules behind. If you substitute table salt (more finely granulated) for recipes that list kosher salt, you must use half the volume indicated in my recipes.

Substitutions are hard.

That said, substitutions aren’t impossible but can be the toughest part of recipe development. Small swaps, like reduced-fat milk (2% fat) for whole milk (3.5% fat), usually work fine. However, bigger changes—such as replacing oil with applesauce or sour cream with Greek yogurt—can significantly impact texture and density.

Be wary of general, all-purpose substitutions in baking; I find that usually there is never a one size-fits-all solution. I carefully select ingredients for my recipes, so for the best results, start with the original recipe and modify with caution.

Read all the recipe instructions before beginning.

I’m in the “Pre-read the Chapter before Class Lecture” club... and I invite you to join! Baking new recipes can be intimidating, so let’s set you up for success. I want you to think about timeframes. Most fillings and frostings can be made ahead of time, and give you an extra day for mental space. Also, as you become a more proficient baker, you can anticipate and recognize steps. (“Oh, this has a meringue step, so I’ll need an extra clean bowl…” etc.) Ensure you go down the ingredient list and have everything at the right temperature.

Ingredients

  • 8 g (1 tablespoon) powdered sugar, unsifted, if not clumpy
  • ½ + ⅛ teaspoon vanilla extract
  • a small pinch of fine sea salt

  • 301 g (1 ⅓ cups) unsalted butter
  • 23 g (3 tablespoons) powdered sugar, unsifted, if not clumpy
  • 10 g (2 teaspoons) vanilla extract
  • ⅛ teaspoon salt (start with a pinch)

Instructions

  1. Dissolve the sugar in the eggs.
    You can use either a double boiler (bain marie) or a microwave for this step. I prefer the microwave as it’s much quicker and requires less cleanup.

    For the double boiler method:
    Find a pot that will hold a large metal bowl without touching the bottom of the pot. Fill the pot with water so the bowl is directly above the water, but not touching it. The closer the bowl is to the surface, the better, as this is where heating will be most efficient. Remove the bowl for now and heat the water to a gentle simmer.

    Add the pasteurized eggs to your metal bowl. Add the white granulated sugar, then immediately mix with a spatula until it is evenly distributed. 

    Place the bowl on top once your double boiler is at a gentle simmer. Use a spatula to gently stir periodically and heat the egg syrup until all the sugar has dissolved. No need for a thermometer, just use your fingers to feel the mixture, which should be free of sugar granules when it’s ready. Pour the egg mixture into a large measuring cup and allow it to cool to room temperature.

    For the microwave method:
    Add the pasteurized eggs to a heatproof measuring cup. Add the white granulated sugar, then mix with a spatula.

    Microwave on high (1200 watts) for 20-second intervals, stirring after each heating step. Repeat this until all the sugar has dissolved. Allow to cool to room temperature.
  1. Prepare the frosting butter.
    Add the slightly softened butter to the stand mixer bowl. With the whisk attachment, mix on high speed for about 2 minutes, scraping down the sides at least once. After mixing, the butter will be lighter in color, smooth, soft, and will form a ball inside the whisk.

    Add the powdered sugar, vanilla extract, and a small pinch of salt to the butter, then whisk again at medium-high speed for 1-2 more minutes.

  2. Combine the cooled egg syrup with the butter.
    Ensure your egg syrup is at room temperature, then add 4 to 5 additions, whipping for about 30 seconds after each. Once all the egg syrup has been added, mix for an additional minute on high speed.
  3. Flavor and smooth the frosting.
    The whisk attachment introduced many air pockets, so switch over to the paddle attachment and mix on low speed for at least a few minutes to smooth out the frosting. Give the frosting a taste and adjust for vanilla and salt, if needed.

Adriana's Notes

*Egg products sold in cartons here in the US require USDA pasteurization protocols, which heat the eggs over extended periods of time. This kills disease-causing bacteria, making the product safe to consume straight from the container. The temperature is not quite high enough to coagulate (or solidify) the eggs, so they remain liquid. Therefore, they are safe to use in this frosting without the high-heat safety steps of traditional French Buttercreams that use raw eggs.
