Macaron Troubleshooting Guide

A comprehensive macaron troubleshooting guide with photos, possible causes and how to avoid the most common macaron issues!

Since 2012, I’ve made thousands of macarons in my home kitchen with many trials and errors, as well as picture-perfect macarons! And yes, I’ve had pretty much every problem imaginable!!

In the process, I’ve gained lots of tips and tricks to solve those frustrating issues and, most importantly, how to avoid them in the first place.

Remember, sometimes, macarons fail for no apparent reason and leave us scratching our heads.

But I encourage you to never give up on macarons. The joy of watching your macarons grow those ruffled feet and pulling out perfectly round macarons with shiny smooth tops is simply priceless.

I swear, every single time, when I see my macarons through the oven door puffing up and baking perfectly, I can’t help but do a little happy dance in my kitchen! Pure joy, I’m telling ya!

What’s a perfect macaron?

Perfect macaron is very subjective. To me, a perfect macaron has the following characteristics:

• Smooth shells
• Ruffles feet
• Full inside

HOW TO FIX cracked macarons:

1. Be sure to tap the baking sheet right after piping macaron shells. And use a toothpick to pop large air pockets visible on the surface.
2. When it’s too humid, the shells don’t develop good skin, which leads to the next point.
3. When the shells haven’t rested long enough to develop skin on top, steam releases from anywhere cause macarons to crack on top.
4. Take your time to make nice and sturdy meringue, especially when you’re making French meringue. Watch my video on French Meringue 101 to learn all the tips to make the most stable French meringue.
5. Too hot oven can also cause cracks in macaron shells. Make sure to get an oven thermometer to double check the temperature inside the oven without relying on what oven says.

How to prevent erupted volcano macarons:

Never touch your unbaked macaron shells with wet fingers to push down pointy end. Instead tap the baking sheet well. And if the pointy end doesn’t melt into the batter, you can either baking them as is, or scrape the batter back into a bowl and mix for a little more until the batter is at correct consistency.

How to fix hollow macaron shells:

Hollow macarons are so common, and I personally battled with this issue for a long time. Now, I consistently get full, meaty macarons straight from the oven.

Since it’s a complex issue, I dedicated a separate post on how to fix hollow macarons.

How to prevent no feet macarons:

1. When the batter is too wet, macarons don’t develop those ruffled feet. The most common causes for wet batter: excess liquids, like extracts, lemon/lime juice, liquid food coloring, too much gel food coloring, etc.
2. In some cases, especially in humid climates, aging egg whites might be beneficial. During aging, egg whites loose some of its moisture.
3. When the meringue isn’t whipped to stiff peaks, it doesn’t have strong enough structure to lift macarons. Watch my French Meringue 101 video for visual cues for proper meringue.
4. When macaron batter is over-mixed, there’s not much air bubbles left to give the shells lift during baking. Therefore, they come out flat without feet.
5. Also, if macarons weren’t rested to form a skin before baking, it could cause no feet macarons. And if the shells were rested for too long, it can also negatively affect the batter, because meringue loses its stability when sat for too long. Keep checking the shells every 15 minutes and put them in the oven as soon as they don’t stick to your fingers.
6. If the oven is not hot enough, macarons won’t rise as air bubbles in the meringue need heat to expand to lift the shells, creating that pretty feet at the base.

How to prevent soft, wrinkly shells:

Excess moisture and/or fat is the #1 cause for soft, wrinkly shells. And there’re number of culprits for excess moisture/fat in the batter:

1. Adding liquid extracts, juices or liquid food coloring
2. Adding cocoa powder, freeze-dried fruits, etc.
3. Under-mixed meringue also contains too much moisture
4. Oily almond flour, or almond flour that has been opened for too long

Cocoa powder contains fat which could potentially cause soft, brownie-like macaron shells. And freeze-dried fruits absorb moisture from the air fast and could cause soft, wrinkly shells as well.

how to fix and prevent thick batter issue:

1. Be sure to weigh the ingredients carefully. I strongly recommend weighing all the ingredients, including egg whites, with a kitchen scale.
2. Oily almond flour could cause thick batter. Make sure to use fresh almond flour and avoid processing it in a food processor.
3. Too much cocoa powder or freeze-dried fruits can throw the ratio of dry and wet ingredients.
4. When meringue is over-beaten, it gets dry, throwing off the ratio as well.

how to prevent blotchy macarons:

1. Use fresh almond flour that’s not oily. To test, squeeze some almond flour in your hand and see if it holds its shape. If it holds its shape like wet sand, then it’s too oily.
2. Make sure to pipe the shells right away, especially with French meringue batter.

And lastly, don’t dry your macarons for too long. Too thick skin may cause lopsided macarons.
