Instructions

  1. Step 1: In a medium saucepan, whisk together 2 cups unsweetened almond milk, 3 large eggs, 1/2 cup vanilla protein powder, and 1/4 cup erythritol sweetener until smooth.
  2. Step 2: Place the saucepan over medium-low heat and cook, stirring constantly, until the mixture thickens slightly and reaches about 160°F, about 8 minutes — do not let it boil to avoid curdling.
  3. Step 3: Remove from heat and stir in 1 tsp pure vanilla extract, 1 tsp ground cinnamon, 1/4 tsp ground nutmeg, 1/2 cup heavy cream, and a pinch of salt until fully combined and smooth.
  4. Step 4: Transfer the eggnog to a bowl, cover, and chill in the refrigerator for at least 2 hours to allow flavors to meld and the eggnog to thicken further.
  5. Step 5: Serve chilled with a sprinkle of additional cinnamon or nutmeg on top if desired.
