Macarons, the delicate French meringue-based confections, can be a joy to make and a delight to eat. However, for many bakers, the process of crafting these intricate treats can be a source of frustration, particularly when they turn out flat and hollow. If you’re struggling to achieve the perfect, chewy-on-the-inside, crispy-on-the-outside macaron, you’re not alone. In this article, we’ll delve into the common causes of flat and hollow macarons and provide you with practical tips to help you overcome these issues and achieve macaron success.
Understanding the Anatomy of a Macaron
Before we dive into the reasons behind flat and hollow macarons, it’s essential to understand the anatomy of a well-structured macaron. A perfect macaron consists of two main components: the shell and the filling. The shell is the outer, meringue-based layer that provides the macaron’s signature crunch and chew. The filling, typically made from buttercream, ganache, or jam, adds flavor and moisture to the macaron.
A well-structured macaron shell should have a smooth, rounded top, a delicate “foot” at the bottom, and a crisp, chewy interior. The shell should be sturdy enough to hold its shape, yet delicate enough to yield to a gentle bite.
The Role of Meringue in Macaron Structure
Meringue is a critical component of macaron shells, providing structure, texture, and stability. Meringue is made from whipped egg whites and sugar, which are combined to create a stiff, glossy mixture. When meringue is baked, the air bubbles trapped within the mixture expand, creating a light, airy texture.
However, meringue can be finicky, and its behavior is influenced by a range of factors, including temperature, humidity, and technique. If the meringue is not prepared correctly, it can lead to a range of issues, including flat and hollow macarons.
Common Causes of Flat and Hollow Macarons
So, why do macarons turn out flat and hollow? Here are some common causes:
Overmixing the Batter
Overmixing the batter is a common mistake that can lead to flat and hollow macarons. When the batter is overmixed, the meringue becomes deflated, and the air bubbles are pushed out of the mixture. This results in a dense, flat macaron that lacks the characteristic “foot” and chewy interior.
To avoid overmixing, it’s essential to fold the meringue and almond flour mixture gently and briefly, until just combined. This will help preserve the air bubbles in the meringue and ensure a light, airy texture.
Incorrect Oven Temperature
Incorrect oven temperature can also cause macarons to turn out flat and hollow. If the oven is too hot, the meringue will cook too quickly, causing it to puff up and then collapse. On the other hand, if the oven is too cold, the meringue will not cook properly, resulting in a dense, flat macaron.
To ensure that your macarons are baked at the correct temperature, invest in an oven thermometer. This will help you achieve a consistent temperature, which is essential for baking perfect macarons.
Insufficient Resting Time
Macaron batter needs time to rest and mature before baking. This allows the shells to form a skin, which helps them retain their shape and structure. If the batter is not rested for long enough, the shells may not develop properly, resulting in flat and hollow macarons.
To ensure that your macarons have sufficient resting time, allow the batter to sit at room temperature for at least 30 minutes before baking. This will help the shells to form a skin and develop a smooth, rounded top.
Humidity and Weather Conditions
Humidity and weather conditions can also affect the texture and structure of macarons. If the air is too humid, the meringue will absorb moisture, causing it to become sticky and dense. On the other hand, if the air is too dry, the meringue will become brittle and prone to cracking.
To minimize the impact of humidity and weather conditions, bake your macarons on a dry, cool day. If you live in a humid climate, consider using a dehumidifier to control the moisture levels in your kitchen.
Troubleshooting Flat and Hollow Macarons
If you’re struggling with flat and hollow macarons, don’t despair. Here are some troubleshooting tips to help you identify and fix the problem:
Check Your Meringue
If your macarons are turning out flat and hollow, the first thing to check is your meringue. Is it stiff and glossy, or is it soft and weepy? If your meringue is not stiff enough, it may not be holding its shape properly, resulting in flat macarons.
To fix this issue, try increasing the sugar content of your meringue or using a higher ratio of egg whites to sugar. This will help to strengthen the meringue and improve its texture.
Adjust Your Baking Time
If your macarons are turning out flat and hollow, it may be due to incorrect baking time. If the macarons are not baked for long enough, they may not be developing properly, resulting in a dense, flat texture.
To fix this issue, try increasing the baking time by 1-2 minutes. This will help to ensure that the macarons are cooked through and have developed a crispy exterior and chewy interior.
Experiment with Different Flavorings
Believe it or not, the flavorings you use in your macarons can affect their texture and structure. Some flavorings, such as fruit purees or extracts, can add moisture to the batter, causing the macarons to become dense and flat.
To fix this issue, try using different flavorings or reducing the amount of flavorings you use. This will help to minimize the impact of moisture on the batter and ensure that your macarons turn out light and airy.
Conclusion
Flat and hollow macarons can be a frustrating problem, but by understanding the common causes and troubleshooting tips, you can overcome these issues and achieve macaron success. Remember to check your meringue, adjust your baking time, and experiment with different flavorings to find the perfect combination for your macarons.
With practice and patience, you’ll be baking perfect, chewy-on-the-inside, crispy-on-the-outside macarons in no time. Happy baking!

What causes macarons to fall flat?
Macarons can fall flat due to a variety of reasons, including overmixing the batter, incorrect oven temperature, and insufficient resting time. When the batter is overmixed, the air bubbles that are incorporated during the mixing process are deflated, resulting in a dense and flat macaron. Similarly, if the oven temperature is not accurate, it can affect the rise of the macaron, leading to a flat or uneven shape.
To avoid this, it’s essential to mix the batter just until the ingredients are combined, and then stop mixing. It’s also crucial to invest in an oven thermometer to ensure that the temperature is accurate. Additionally, allowing the macarons to rest for the recommended amount of time can help them to develop a strong structure and rise properly.
How do I achieve the perfect ‘foot’ on my macarons?
The perfect ‘foot’ on a macaron is achieved when the shell has a smooth, rounded edge and a delicate ruffle at the base. To achieve this, it’s essential to tap the baking sheet gently after piping the macarons to remove any air bubbles. This helps to create a smooth, even surface and prevents the formation of large bubbles that can cause the foot to become misshapen.
It’s also important to ensure that the macarons are baked at the correct temperature and for the right amount of time. If the macarons are underbaked, the foot may not develop properly, while overbaking can cause it to become too dark or crispy. By experimenting with different baking times and temperatures, you can find the perfect combination to achieve the desired foot on your macarons.
What is the ideal humidity level for making macarons?
The ideal humidity level for making macarons is between 40-60%. If the humidity is too high, the macarons may not develop a strong structure and may become too sticky or chewy. On the other hand, if the humidity is too low, the macarons may become too dry and brittle.
To achieve the ideal humidity level, you can use a dehumidifier or humidifier in your kitchen, depending on the ambient humidity. You can also try making macarons at different times of the day or in different seasons to find the optimal humidity level for your environment.
Can I make macarons in a convection oven?
Yes, you can make macarons in a convection oven, but it may require some adjustments to the baking time and temperature. Convection ovens cook more evenly and quickly than traditional ovens, which can affect the rise and texture of the macarons.
To make macarons in a convection oven, you may need to reduce the baking temperature by 1-2% and the baking time by 1-2 minutes. It’s also essential to keep an eye on the macarons while they are baking, as the convection oven can cause them to cook more quickly than expected.
How do I store macarons to keep them fresh?
Macarons are best stored in an airtight container in the refrigerator to keep them fresh. The container should be lined with parchment paper or a silicone mat to prevent the macarons from sticking.
When storing macarons, it’s essential to keep them away from strong-smelling foods, as they can absorb odors easily. You can also freeze macarons for up to 3 months and thaw them at room temperature when you’re ready to serve. However, it’s best to consume macarons within 3-5 days of baking for optimal flavor and texture.
Can I make macarons ahead of time and assemble them later?
Yes, you can make macaron shells ahead of time and assemble them later. In fact, making the shells ahead of time can help to ensure that they are completely dry and ready to be filled.
To make macaron shells ahead of time, simply bake and cool them as usual, then store them in an airtight container in the refrigerator for up to 3 days or freeze them for up to 3 months. When you’re ready to assemble the macarons, simply pair the shells and fill them with your desired filling.
What is the best way to pair macaron shells?
The best way to pair macaron shells is to match them by size and shape. This ensures that the macarons are visually appealing and that the filling is evenly distributed.
To pair macaron shells, simply sort them by size and shape, then match them up. You can also use a template or a macaron pairing tool to help you match the shells more accurately. By pairing the shells carefully, you can create beautiful and professional-looking macarons that are sure to impress.
