Ingredients

• 2 cups unsweetened almond milk
• 1/2 cup vanilla whey protein powder
• 4 large egg yolks
• 1/2 cup heavy cream
• 1/4 cup erythritol
• 1 tsp ground cinnamon
• 1/2 tsp ground nutmeg
• 1 tsp unsweetened vanilla extract
• a pinch salt
• 1/2 cup water

Instructions

1. Step 1: In a medium saucepan, whisk together 2 cups unsweetened almond milk, 1/2 cup erythritol, 1 tsp ground cinnamon, 1/2 tsp ground nutmeg, and a pinch of salt. Heat over medium-low heat until the mixture is warm but not boiling, about 3-4 minutes, stirring occasionally.
2. Step 2: In a separate bowl, vigorously whisk 4 large egg yolks with 1/2 cup water until pale and slightly thickened, about 2 minutes.
3. Step 3: Slowly temper the egg yolks by adding 1/2 cup of the warm milk mixture to the yolks while whisking constantly. Then pour the yolk mixture back into the saucepan with the remaining milk mixture.
4. Step 4: Cook over low heat, stirring constantly with a wooden spoon, until the mixture thickens enough to coat the back of the spoon, about 5-6 minutes. Do not let it boil.
5. Step 5: Remove from heat and whisk in 1/2 cup heavy cream, 1/2 cup vanilla whey protein powder, and 1 tsp unsweetened vanilla extract until smooth and fully combined.
6. Step 6: Pour the eggnog into a pitcher and chill in the refrigerator for at least 2 hours before serving. Stir well before serving and optionally garnish with additional ground nutmeg.
