In a bowl, mix the egg yolks and 1/3 of the erythritol.
In a separate bowl, mix the heavy cream and vanilla.
Slowly whisk the heavy cream into the egg yolks.
Pour your cream mixture into the ramekins.
Place them in a deep casserole dish or roasting pan.
Fill the outer dish up with boiling water…but don’t get any in the ramekins!
Bake at 350F for 45 minutes. When it’s done, you’ll notice the custard is firm on the outside and a little jiggly in the center.
Allow to cool.
Spoon the rest of the erythritol onto each custard.
Using a torch (or broiler) slowly caramelize the sugar substitute.
Let it cool and harden, then enjoy!
