1. In a saucepan, combine the heavy cream, almond milk, and powdered erythritol. Heat the mixture over medium heat until it starts to simmer, stirring occasionally.
2. In a separate small bowl, sprinkle the gelatin over 1/4 cup of cold water. Let it sit for a few minutes to bloom.
3. Once the cream mixture is simmering, remove it from the heat and stir in the vanilla extract.
4. Microwave the bloomed gelatin for about 10 seconds until it becomes liquid. Pour the gelatin into the cream mixture and whisk until well combined.
5. Divide the mixture evenly among four ramekins or dessert glasses.
6. Place the ramekins in the refrigerator and let them set for at least 4 hours or overnight.
7. Once set, you can serve the panna cotta as is or garnish with fresh berries if desired.
