Equipment

  • 6 oz ramekins
  • Baking dish
  • Mixing bowls
  • Whisk

Ingredients

  • 1/4 cup sugar-free pancake syrup
  • 1/4 teaspoon blackstrap molasses optional
  • 1 cup heavy whipping cream
  • 3 tablespoons Swerve or equivalent granulated sweetener
  • 1 teaspoon vanilla
  • 2 large eggs
  • 1 large egg yolk
  • 1/8 teaspoon salt

Instructions

  • Set the oven to 350 °F and gather three 6 oz ramekins with a baking dish that accommodates them. The ramekins should sit flat without crowding.
  • Arrange the empty ramekins in the dish, pour water around them to a depth of 1 inch, then lift them out and transfer the water-filled dish to the oven. The bath will heat while you prepare the fillings.
  • Stir the pancake syrup with the blackstrap molasses, if using. The sauce should look evenly blended.
  • Divide the sauce evenly among the three ramekins. Each bottom should have a syrup layer.
  • Stir the cream, granulated sweetener, salt, and vanilla together in a medium bowl until the sweetener dissolves. The mixture should no longer feel gritty when stirred.
  • Break up the whole eggs and extra yolk with a whisk in a separate small bowl. The whites and yolks should form a uniform mixture.
  • Gradually introduce the egg mixture into the cream while whisking gently. Stop when the custard looks consistent, without separate egg streaks.
  • Spoon the custard over the syrup in equal portions, then carefully lower the filled ramekins into the heated water bath. Syrup rising around the custard’s edges is normal.
  • Bake for 35–45 minutes, checking for a set surface with movement at the center. A gentle nudge should reveal a soft central wobble rather than liquid sloshing.
  • Leave the ramekins in the baking dish for 10 minutes after removing it from the oven. The delicate custard will begin to settle as it cools.
  • Lift the ramekins from the bath and refrigerate for at least 2 hours. Chilling gives the custard the firmness needed for unmolding.
  • Trace a thin knife around the inside wall of each ramekin when ready to serve. Keep the blade close to the dish to preserve the custard’s sides.
  • Cover each ramekin with a plate and turn the pair over together. The ramekin should now sit upside down on the plate.
  • Give the inverted ramekin a gentle jiggle, then lift it away once the flan releases and serve cold. The sauce should pool around the custard.

Notes

Texture tip: Whisk the eggs and cream gently to limit foam, and optionally pass the combined custard through a fine-mesh sieve before baking to catch any unmixed egg strands.
Doneness: Remove the flan from the oven when the outer edges are set and a gentle nudge reveals a cohesive, gelatin-like wobble in the center rather than liquid sloshing.
Serving tip: Chill the custards completely before loosening the edges with a thin blade. If the bottom refuses to release, briefly rest the bottom of the upright ramekin in warm water without wetting the custard, then invert again.
Storage: Keep chilled flans covered in their ramekins until you are ready to serve, unmold only the portions needed, and store any leftovers in a covered container in the refrigerator.
