Cracked Macarons: Why They Happen and How to Fix Them

If you’ve ever pulled a fresh batch of macarons out of the oven and saw ugly cracks, you’re not alone. Cracks are one of the most common frustrations for bakers, but they’re not a death sentence. Below you’ll find straight‑forward reasons why cracks appear and easy steps to keep your shells smooth.

What Causes Cracks?

First, know the usual suspects:

• Under‑mixing the batter. If the batter isn’t smooth and glossy, the shells won’t hold together properly.
• Over‑mixing. Too much mixing breaks down the air bubbles, making the shells dry and prone to splitting.
• Oven temperature. Too hot or too cool can make the top set too fast or too slow, leading to cracks.
• Humidity. High moisture in the air stops the shells from forming a firm crust.
• Improper cooling. Leaving the tray in the hot oven can cause sudden temperature changes that crack the shells.

Spotting the exact cause helps you tweak the right step.

Simple Fixes Before You Bake

Here are three quick adjustments you can make right now:

1. Test your batter consistency. When you lift the spatula, the batter should flow slowly and form a thick ribbon that disappears after a few seconds. If it’s runny, keep folding; if it’s stiff, stop.
2. Set a reliable oven thermometer. Most home ovens run a few degrees off. Aim for 300°F (150°C) for most French‑style macarons.
3. Use a dry day or lower the humidity in your kitchen. A dehumidifier or an air‑conditioner can make a big difference.

These tweaks usually stop cracks before they start.

Rescuing Cracked Shells

If you already have cracked shells, don’t toss them. You can still turn them into tasty treats:

• Make a crust. Crush the cracked shells, mix with a bit of melted butter, and press into a pan for a quick tart base.
• Layer them. Use the cracked pieces in a layered dessert, like a macaron parfait with fruit and cream.
• Turn them into crumbs. Pulse in a food processor, then sprinkle over ice cream or use as a topping for mousse.

All three ideas give you a tasty use for shells that didn’t survive the first round.

Finally, keep a small notebook of the temperature, mixing time, and humidity for each batch. Over time you’ll see patterns and nail the perfect, crack‑free macaron every time.

With these tips, cracked macarons become a learning step, not a failure. Happy baking!
