- To make the filling, sprinkle the gelatin in a small bowl filled with 1 tbsp of water and set aside. 
- In a medium saucepan, heat the heavy whipping cream and macadamia milk over a medium-high heat. 
- While it’s heating, place the egg yolks into a bowl together with the sweetener, vanilla and salt. Using a hand mixer, mix until frothy and well combined. 
- Once the cream mixture starts simmering and foam starts to form, remove from the heat. Use a ladle to gradually add the hot mixture into the egg mixture. Keep whisking constantly or the mixture will turn into scrambled eggs. 
- When the eggs have been tempered, place the mixture into the saucepan. 
- Whisk continuously and cook over a medium heat until it starts to thicken, about 2 minutes. Cook for another 3 to 4 minutes. 
- Remove from the heat and add the bloomed gelatin. Then stir in the butter. 
- Pour the mixture into a container and let it cool to room temperature.  
- Cover with a lid and refrigerate for at least 3 hours or overnight. You can make this one week ahead of time.
