This simple recipe is for an easy lemon white chocolate ganache that doesn’t require cream. Instead, the cream is replaced by fridge staples - milk and butter. Combined with the lemon, these ingredients almost create a buttermilk in your mixture.
This lemon white chocolate ganache is perfect for your icing your cakes and cupcakes or filling your chocolates or macarons. All in all, it’s versatile and delicious!
This ganache has a slightly more curd-like consistency than a true ganache, and it's still super creamy and I think this pairs brilliantly with lemon - the numero uno of the curd world.
✏️ Making a tasty and easy recipe
Cream isn’t something I usually stock in my fridge. So, if the mood strikes and I want to bake a cake (or I forgot it was someone’s birthday and needed to do some last-minute baking), then I wanted something quick and easy I could whip up.
Lemons, milk, butter and white chocolate are usually ingredients I have in my fridge and cupboard this so this works great as a last-minute cake frosting. It also works great all the time, because it really lets the zesty lemon flavour shine through.
🥘 Ingredients notes
Using good quality white chocolate for your ganache really improves the flavour. I’ve tried this before with cheap chocolate and you can definitely taste a difference! I like to use the fancy couverture white chocolate (this one by Callebaut), but any good quality white chocolate will work great.
Similarly, I recommend using real butter for this recipe rather than a baking blend of margarine or other spread.
When measuring your ingredients, I always recommend using weights rather than cups where possible for greater accuracy.
🔪 Equipment notes
Store your lemon white chocolate ganache in the fridge until ready to use.
When storing the ganache for later use, I usually leave it in the bowl I made it in, with cling film / plastic wrap over the top. Alternatively, you can transfer it to an airtight container to store in the fridge instead.
Your ganache should keep for up to 4 days in the fridge before use.
It's worth noting that the shelf life of what you put the ganache in will be limited by the ganache's freshness, so it's better to use the ganache as soon as possible.
💭 Top tips for success
- When you heat up the mix, it’s important to take it slow. Don’t be tempted to heat the mix for too long at once and cause it to boil, as you can end up burning the chocolate and won’t have a nice and smooth texture to your ganache.
- It’s likely that you’ll get a few lumps of unmelted white chocolate after you let the chocolate sit in the hot butter and milk mix for a few minutes. That’s ok, just keep beating the mix for a minute and if you still have lumps, then whack the mix into the microwave for another 10secs, or put back onto the double boiler for 30secs, and then remove from the heat and beat until it’s smooth. You can repeat this process a couple of times until you get a beautiful lump-free mix.
- When you first make your ganache, it will be quite thin as you can see in the image below. Don’t worry though, it will firm up as it sets. The time it takes to set can be quite a while, depending on whether you use the fridge or freezer, or what your room temperature is if you leave it on the side. It’s fastest to put this in the freezer for 30 mins then move this to the fridge for another 30mins.

♻️ Alternatives and substitutions
I love my lemon ganache to have quite the zesty kick, so I put 2 lemons of zest and juice into the mix. If you prefer a more subtle flavour, then try adding 1½ lemons' zest and juice instead.
Instead of lemon, you can swap this for another citrus fruit, such as lime. For this, I would use 3 limes instead of the 2 lemons.
