Ingredients

White Chocolate Ganache Filling

  • 210g finely chopped white chocolate or white chocolate chips (1 1/4 cups)
  • 95g heavy cream (1/3 cup + 1 Tbsp)

Equipment

Instructions

White Chocolate Ganache

  1. The 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.
  2. Place 210g of white chocolate in a medium-sized bowl and set aside.
  3. Pour 95g heavy cream into a heat-proof bowl and heat in 15-second intervals in the microwave until it just begins to bubble (this usually takes me about a minute). If you don't have a microwave, heat the cream over medium-high heat in a saucepan until it starts to bubble and steam.
  4. Pour the heavy cream over the white chocolate. Make sure all the white chocolate is submerged beneath the cream. Let the mixture sit for a couple of minutes.
  5. Use an immersion blender or a spoon to mix the ganache until 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.
  6. 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.
  7. 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.
  8. Place the finished macarons in an airtight container and chill in the fridge overnight, then enjoy! Store any leftover macarons in the fridge.

Notes

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.

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 your 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.
  • 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.
  • If possible, use an immersion blender to make sure your ganache turns out silky smooth!
  • 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.
  • 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.

Making This White Chocolate Ganache in Advance & Storage Tips

  • Macarons filled with this ganache should mature for a few hours or overnight in the fridge before being eaten. This gives them time to develop the best texture and taste.
  • Refrigerate macarons filled with this ganache for up to 5 days in an airtight container.
  • Freeze macarons with this filling for up to a month in an airtight container.
  • Make this ganache ahead of time too or save any leftover ganache! Store in an airtight container in the fridge for up to a week.
