Preheat your oven to 350
Put 2 cups of heavy cream in a saucepan and bring it to barely simmering. Do NOT boil!
In a separate bowl, separate egg yolks & whisk the yolks with 1/4 cup of the sweetener and 1 tsp of vanilla.
When cream is ready, slowly add it to the egg mixture, stirring constantly until it's well blended.
Pour mixture into 4 ramekins & place in a baking dish. (A 13 x 9 would work).
Heat up 2-3 cups of water either on the stove or in the microwave to hot (not boiling).
Pour the water into the baking dish, filling until the water comes about 1/2 way up the ramekins. Do not fill past that.
Carefully place the baking dish on the center rack in the oven and bake 45 - 50 minutes before removing. (This could vary with different ovens. Adjust the time, accordingly) You want the tops to be somewhat firm and slightly golden.
Remove from oven and take ramekins out of the water & cool on the counter before covering and chilling in the refrigerator.
Once chilled, top with remaining sugar-free sweetener and place under a low broiler for 1-2 minutes to melt sweetener until golden brown. Keep an eye on them to make sure they don't burn. If using a food torch, just hold the torch over each ramekin, melting the sugar. Make sure to keep it moving.
Serve as is or top with whipped cream and enjoy!
