How to fix oily ganache
?
Visible oil pooling around a grainy or separated mixture usually means your ganache has split. This can happen after overheating or when the balance of chocolate and liquid is unsuitable. A normal, even shine is different from separate droplets or puddles of fat.
Do not throw it away immediately. A split batch can often be brought back together, although badly scorched chocolate cannot be restored by repairing the texture.
How to fix oily ganache
Stop heating first. If the mixture is very hot, let it cool slightly before attempting a repair.
For a small test portion, try adding a teaspoon of warm drinking water and stirring thoroughly. Add further small amounts only as necessary, stopping when the mixture becomes smooth again.
The water should be warm, not boiling. Avoid pouring in a large quantity at once, as this can make the finished result too soft.
This method adds liquid without introducing more fat. Read King Arthur Bakingâs explanation of how to fix broken ganache for the technique and its reasoning.
Can a hand blender help?
An immersion blender can help create a fine, even mixture. Use a suitable deep container and keep the blender head submerged to avoid incorporating unnecessary air.
Valrhona uses immersion blending in its professional ganache methods to refine the emulsion. Blending is a useful technique, but it does not remove the need for an appropriate recipe and temperature.
Avoid lifting the running blades through a warm mixture, which can cause splashes.
Should you drain off the oil?
Draining the oil is not our recommended first step. It removes part of the recipe rather than bringing the ingredients back together, making the final result less predictable.
Chilling may make the mixture appear firmer, but firmness alone does not demonstrate that the separation has been corrected.
Let your repaired sample settle and check its texture before treating the whole batch.
How do you rescue split white chocolate ganache?
Use particular care with white chocolate. Start with a recipe designed for the chocolate you are using rather than substituting it directly into a dark chocolate formula.
Professional recipes use different proportions and working temperatures for white, milk and dark varieties. There is no single temperature or ratio that suits every batch.
If it separates, avoid repeated strong heating. Try the repair on a small portion first and assess the cooled result before proceeding.
Can you use a rescued batch to cover a cake?
Possibly, but check how it sets before covering your cake.
Spread a small amount on a plate or spare cake board and allow it to reach the temperature at which you intend to work. Check that it:
- Spreads smoothly.
- Holds its shape sufficiently for the design.
- Does not release visible oil.
- Has the flavour and texture you need.
Adding liquid changes the original recipe. A successful repair may therefore suit a filling or sauce better than a firm coating beneath sugarpaste.
For an important order, allow time to remake the batch if the test is unsatisfactory.
How can you prevent it happening again?
Use a tested recipe and weigh the ingredients carefully. Note the chocolate brand and type so you can repeat a successful result.
When softening a chilled batch, use gentle heat and stir between short heating intervals. For the full method, read our guide to reheating ganache without overheating it.
Keep a brief record of any adjustments. Recording the recipe, chocolate and result is more useful than relying on memory when preparing the next cake.
Does repairing it change its storage life?
Restoring a smooth texture does not establish that a batch is safe to eat or extend its storage life.
Follow suitable guidance for the recipe and its handling history. If you have changed the ingredients, do not assume the original shelf life still applies.
For help checking your ingredients, read our guidance on double cream use-by dates.

Glad it wasn’t wasted! Googled ‘how to fix oily ganache and found this quoted
Fortunately, it was easily fixed, thanks to the advice in Chocolates and Confections. First, we tried simply re-warming it and stirring. When that failed, we added some warm milk, bit by bit, to increase the amount of water in the mix. Slowly, the ganache came back together. When it no longer seemed oily, we poured it into a frame and continued with the recipe. It worked perfectly, providing further proof that a broken emulsion isnât the end of the world!
It is always good to learn from someone else’s mistakes. I will watch carefully how I heat the cream!
OH MY GOSH! thank you SO much! You have just saved my ganache by posting this đ xo
Unfortunately I didn’t see this post and threw out 400 grams of ganache which had split (ouch! talk about pouring money down the drain). I’ve always believed there was no way back once that happened, now I know different, so thank you very much for this very useful piece of information.
Ouch is right! What a shame. I always google mistakes just in case it has happemed to someone else who rectified it. Trouble is that always leads you to other interesting facts. Still I’m often full of useless, sometimes useful information hence you often hear me say ‘ooh I’ve read something about that’.

I Â overheated my white chocolate ganache the other day and almost threw it out as it was awful and oily. I then decided to let it cool a bit and added cold double cream slowly while whisking . It came back together and became all creamy and lovely again. Â I must remember not to rush white chocolate!
Thank you all, I had the bin lid open and was about to throw my mixture away, it was all grainy and swimming in oil. I used a combination of your answers, I drained off the extra oil and added some warm milk and I didn’t have to throw it in the bin. Everything came together in the end. Thank you
Oh my ganachness you wonderful lovely peeps!!! You have just saved me soooooo much money! I was going to throw out my bowl of oily yuckiness when I thought, no, wait a mo someone will know something about this!!! And you did, and now, after spooning off some of the oil and adding some warmed milk – YEAH ALL IS GOOD AGAIN!!!!!!!!!!!! Thank you so much!!!
Your tip just saved my ganash as well Thankyou so much xxx
Great job!
I’ve just made ganache for the second time. First time it was perfect, this time it looked a little different (grainy) so added some extra warmed up cream and it split. Urgh. I am glad I came here and read these tips so thank you. My ganache may be saved after all. And my purse! đ
Have to be careful how corn syrup or glucose is used in ganache as it can cause it to seize.
Thank you so much – finally an answer to my problematic white ganache. Added the cold cream and it worked!!!
Yeh
I didn’t believe it!,, I too slit my choc. Ganache and thanks to you lovely ladies I have managed to save a full batch of now lovely smooth not grainy choc. Ganache. I spooned of the oil as best I could and added a little warmed cream first, then just kept adding bit by bit some warmed milk. YES YES YES it’s great. Saved a fortune.
Thank you all again.
