First, get your oven ready! Preheat it to 300°F (150°C). While it's heating, boil 1-2 quarts of water to prepare for a relaxing water bath for your custards later.
Gently warm the heavy cream in a saucepan over medium-high heat. Look for small bubbles forming around the edges – that's your cue to remove it from the heat before it boils. Do not let it come to a full boil.
While the cream is warming, in a separate bowl, whisk together the egg yolks, whole egg, and confectioners' Monk fruit/Allulose blend until they are smooth and well combined.
Once the warm cream is ready, slowly pour it into the egg mixture, whisking constantly to ensure everything blends beautifully without scrambling the eggs. Stir in the pumpkin puree, pumpkin pie spice, and vanilla extract until uniform.
Divide this lovely custard mixture evenly into 6 ramekins. Place these ramekins inside a larger oven-safe baking pan. Carefully pour the boiling water around the ramekins, filling the pan about halfway up their sides.
Gently transfer the pan to the preheated oven and bake for 50-60 minutes. The crème brûlée is done when the edges are set, but the center still has a slight jiggle. Let them cool at room temperature for 15 minutes, then chill them in the refrigerator for at least 1-2 hours, or until fully set and wonderfully cold.
When you're ready to indulge, sprinkle about 2 1/2 teaspoons of granular Swerve over the top of each chilled crème brûlée. Use a kitchen torch to caramelize the Swerve until it's golden and bubbly – it'll harden into a delightful crunchy top in about 2 minutes. No torch? No problem! A broiler works too: just keep a very close eye on it for 1-2 minutes to prevent burning.
