Ganache can be a lot of different consistencies and flavors, but this white chocolate ganache for macarons is the perfect macaron filling.

It’s silky-smooth, decadent, and absolutely delicious. And the best part is that it’s made with only 2 ingredients!! It doesn’t get much easier than that.

I used this recipe to fill French macarons, but it would work great with Italian macarons or Swiss macarons too.

How to Make This White Chocolate Ganache for Macarons

This white chocolate ganache filling needs about 2 hours to set, so I recommend making it first! It can also be made up to a week in advance. I usually make it the night before.

After heating the cream and pouring it over the white chocolate, let the mixture sit for a couple of minutes.

Then mix it together with either an immersion blender or a spoon.

Once the mixture has come together and is smooth, press a piece of plastic wrap flush against the ganache and place the bowl in the fridge to chill.

Chill for at least 2 hours, if not overnight. When you’re ready to use this ganache, place it in a piping bag fit with a large round piping tip.

It should be thick enough to scoop into the piping bag and hold its shape.

Pipe a thick dollop of white chocolate ganache on one macaron shell.

Gently press a second shell on top of the ganache to create a sandwich.

Place the finished macarons in an airtight container and chill in the fridge overnight, then enjoy! Store any leftover macarons in the fridge.

Recipe Yield

This recipe makes enough ganache to fill about 25 macarons. You can double or triple this recipe to fill more macarons if needed, but it will need more time to set.

For reference, I usually pipe my macarons with a diameter of 1 3/4 inches, so they’re about the size of a standard macaron.

White Chocolate Ganache Macaron Filling – Substitutions and Swaps

As I mentioned above, this recipe is made using just two ingredients!!

Heavy Cream – Use heavy cream or heavy whipping cream, not milk or half and half. You need a high-fat percentage to allow the ganache to come together and have a smooth texture.

To make dairy-free white chocolate ganache, use coconut cream in place of the heavy cream in this recipe.

White Chocolate – Use any type of good quality white chocolate. This includes white chocolate bars, couverture, or chunks.

You can use white chocolate chips if needed but be sure to use a brand like Ghirardelli or Guittard.

Tips for Making the Best White Chocolate Ganache Macaron Filling

• Make this white chocolate ganache before you make the macaron shells. This will give it time to set.
• Measure the ingredients with a kitchen scale. You really need to be precise with this recipe.
• Use good quality white chocolate. It will make the ganache taste better and give it the best possible consistency.
• If you notice bits of unmelted white chocolate in the ganache once it’s combined, heat it in the microwave for another 15 seconds, let it rest for 30 seconds, then give it another stir. Repeat this process as needed until all the chocolate is melted and the ganache is smooth.
• If possible, use an immersion blender to make sure your ganache turns out silky smooth!
• Once you’ve filled macarons with this ganache, pop them in the fridge to help the ganache set.
• To make dairy-free white chocolate ganache, use coconut cream in place of the heavy cream in this recipe.
