French buttercream, also known as pâté à bombe, is a rich and decadent frosting made from egg yolks, sugar, and butter. It’s a popular choice among bakers and pastry chefs due to its smooth, creamy texture and rich flavor. However, achieving the perfect consistency can be a challenge, and many bakers find themselves struggling with a runny French buttercream. In this article, we’ll explore the reasons behind a runny French buttercream and provide tips and tricks for achieving the perfect consistency.
Understanding the Science Behind French Buttercream
Before we dive into the reasons behind a runny French buttercream, it’s essential to understand the science behind this type of frosting. French buttercream is made by whipping egg yolks and sugar together until they become light and airy, then slowly adding in melted butter. The egg yolks provide structure and emulsification, while the sugar adds sweetness and helps to strengthen the egg yolks. The butter adds richness and flavor, but it also plays a crucial role in determining the consistency of the frosting.
The Importance of Temperature
Temperature is a critical factor in determining the consistency of French buttercream. If the butter is too warm, it can cause the frosting to become too thin and runny. On the other hand, if the butter is too cold, it can cause the frosting to become too thick and stiff. The ideal temperature for making French buttercream is between 70°F and 75°F (21°C and 24°C). This temperature range allows the butter to melt slowly and evenly, creating a smooth and creamy frosting.
The Role of Egg Yolks
Egg yolks play a crucial role in determining the consistency of French buttercream. If the egg yolks are not whipped enough, they can cause the frosting to become too thin and runny. On the other hand, if the egg yolks are over-whipped, they can cause the frosting to become too thick and stiff. The ideal consistency for egg yolks is when they become light and airy, but still hold their shape.
Common Reasons for a Runny French Buttercream
Now that we’ve explored the science behind French buttercream, let’s take a look at some common reasons why your French buttercream may be runny.
Over-Whipping the Egg Yolks
Over-whipping the egg yolks can cause them to become too light and airy, leading to a runny frosting. This is because the egg yolks are no longer able to hold their shape, causing the frosting to become too thin.
Using the Wrong Type of Butter
Using the wrong type of butter can also cause your French buttercream to become runny. European-style butters, which have a higher fat content than American-style butters, are ideal for making French buttercream. If you’re using a lower-fat butter, it may not provide enough structure and richness to the frosting.
Not Using Enough Sugar
Not using enough sugar can also cause your French buttercream to become runny. Sugar helps to strengthen the egg yolks and provide structure to the frosting. If you’re not using enough sugar, the frosting may become too thin and runny.
Adding the Butter Too Quickly
Adding the butter too quickly can cause the frosting to become too thin and runny. This is because the butter is not able to melt slowly and evenly, causing the frosting to become too warm and thin.
Tips and Tricks for Achieving the Perfect Consistency
Now that we’ve explored the common reasons behind a runny French buttercream, let’s take a look at some tips and tricks for achieving the perfect consistency.
Using a Thermometer
Using a thermometer can help you to achieve the perfect temperature for making French buttercream. By monitoring the temperature of your butter and egg yolks, you can ensure that they are within the ideal range for making French buttercream.
Whipping the Egg Yolks to the Right Consistency
Whipping the egg yolks to the right consistency is crucial for achieving the perfect consistency. The ideal consistency for egg yolks is when they become light and airy, but still hold their shape.
Adding the Butter Slowly
Adding the butter slowly can help to prevent the frosting from becoming too thin and runny. By adding the butter slowly, you can ensure that it melts evenly and provides the right amount of structure and richness to the frosting.
Using the Right Type of Sugar
Using the right type of sugar can also help to achieve the perfect consistency. Granulated sugar is ideal for making French buttercream, as it provides a smooth and even texture.

What is French buttercream and how does it differ from other types of buttercream?
French buttercream is a type of buttercream made with egg yolks, sugar, and butter. It is different from other types of buttercream, such as American buttercream, which is made with butter and powdered sugar. French buttercream is known for its rich, creamy texture and delicate flavor. It is often used to frost cakes and pastries, and is a popular choice among professional bakers.
The key to making French buttercream is to cook the egg yolks and sugar together until they reach a temperature of 160°F to 180°F. This process, known as tempering, helps to thicken the mixture and give it a smooth, creamy texture. Once the egg yolks and sugar have been tempered, they are slowly whipped together with softened butter until the mixture becomes light and fluffy.
Why is my French buttercream runny?
There are several reasons why your French buttercream may be runny. One common reason is that the egg yolks and sugar were not cooked to a high enough temperature during the tempering process. If the mixture is not heated enough, it will not thicken properly, resulting in a runny buttercream. Another reason may be that the butter was too soft or melted when it was added to the egg yolks and sugar. This can cause the mixture to become too thin and runny.
To fix a runny French buttercream, you can try refrigerating it for about 10 minutes to firm it up. Then, re-whip the buttercream until it becomes light and fluffy again. If the buttercream is still too runny, you can try adding a small amount of powdered sugar to thicken it. However, be careful not to add too much sugar, as this can affect the flavor and texture of the buttercream.
How do I prevent my French buttercream from becoming too runny?
To prevent your French buttercream from becoming too runny, it’s essential to cook the egg yolks and sugar to the correct temperature during the tempering process. Use a candy thermometer to ensure that the mixture reaches a temperature of 160°F to 180°F. Also, make sure to use room temperature ingredients, including the butter and egg yolks. This will help the mixture to come together smoothly and evenly.
Another tip is to add the butter to the egg yolks and sugar slowly and gradually. This will help to prevent the mixture from becoming too thin and runny. You can also try whipping the buttercream for a longer period to incorporate more air and make it lighter and fluffier. By following these tips, you can create a smooth and creamy French buttercream that is perfect for frosting cakes and pastries.
Can I fix a runny French buttercream by adding more butter?
While it may be tempting to add more butter to a runny French buttercream, this is not always the best solution. Adding more butter can actually make the buttercream even thinner and more runny. This is because butter is a liquid at room temperature, and adding more of it can dilute the mixture and make it harder to whip.
Instead of adding more butter, try refrigerating the buttercream for about 10 minutes to firm it up. Then, re-whip the buttercream until it becomes light and fluffy again. If the buttercream is still too runny, you can try adding a small amount of powdered sugar to thicken it. However, be careful not to add too much sugar, as this can affect the flavor and texture of the buttercream.
How do I store French buttercream to prevent it from becoming runny?
To store French buttercream and prevent it from becoming runny, it’s essential to keep it refrigerated. Place the buttercream in an airtight container and refrigerate it at a temperature of 40°F or below. Before using the buttercream, allow it to come to room temperature and re-whip it until it becomes light and fluffy again.
You can also freeze French buttercream for up to 3 months. Simply place the buttercream in an airtight container or freezer bag and store it in the freezer. When you’re ready to use the buttercream, thaw it in the refrigerator overnight and re-whip it until it becomes light and fluffy again.
Can I make French buttercream ahead of time?
Yes, you can make French buttercream ahead of time. In fact, making it ahead of time can help to allow the flavors to meld together and the buttercream to become even more smooth and creamy. To make French buttercream ahead of time, simply cook the egg yolks and sugar together until they reach a temperature of 160°F to 180°F. Then, slowly whip in the softened butter until the mixture becomes light and fluffy.
Once the buttercream has been made, you can store it in the refrigerator for up to 3 days or freeze it for up to 3 months. Before using the buttercream, allow it to come to room temperature and re-whip it until it becomes light and fluffy again. This will help to restore the buttercream’s smooth and creamy texture.
What are some common mistakes to avoid when making French buttercream?
One common mistake to avoid when making French buttercream is not cooking the egg yolks and sugar to a high enough temperature during the tempering process. This can result in a runny or grainy buttercream. Another mistake is adding the butter too quickly or in large chunks, which can cause the mixture to become too thin and runny.
To avoid these mistakes, make sure to use a candy thermometer to ensure that the egg yolks and sugar reach a temperature of 160°F to 180°F. Also, add the butter slowly and gradually, whipping constantly to incorporate it smoothly into the mixture. By following these tips, you can create a smooth and creamy French buttercream that is perfect for frosting cakes and pastries.
