Hi Victoria.
Welcome to the Scoolinary community, and thank you for your question!
I believe you’ve asked this question before, but no worries—we’re happy to share the information again.
Can you let your cake set at room temperature after applying ganache?
Yes, you can leave your cake at room temperature for the ganache to set, but the time it takes to stabilize will depend on the temperature and humidity of your environment.
Ganache setting time at room temperature
At an ideal temperature of 18-22°C (64-72°F) with low humidity, ganache usually takes 2 to 4 hours to fully set.
If the environment is warmer (above 24°C / 75°F), the process will take longer, and the ganache may stay too soft or even melt.
Tips for setting ganache without refrigeration
1. Place the cake in a cool, dry area
Avoid direct sunlight or heat sources.
If it’s too warm, keep it in a well-ventilated room.
2. Avoid condensation
If you decide to refrigerate it, cover it well with plastic wrap and let it come to room temperature before taking it out to prevent condensation.
If your climate is very warm and humid, you might need to refrigerate it briefly before decorating, but be sure to take the necessary precautions.
We hope this information helps.
Best regards!
