Sugar-Free Keto Eggnog Ingredients
For the Eggnog Base
• Egg Yolks – Adds creaminess and helps thicken the eggnog.
• Almond Milk or Coconut Milk – Provides a dairy-free base for a lighter texture; substitute for regular milk if you prefer.
• Heavy Cream – Adds richness to the drink; for a dairy-free option, use coconut cream.
• Erythritol (or any sweetener) – Delivers sweetness without calories or carbs, making it essential for this sugar-free keto eggnog.
For the Flavoring
• Cinnamon – Infuses warmth and spice; freshly ground is best for a stronger flavor.
• Nutmeg – Essential for that classic eggnog aroma; always use freshly grated for optimal taste.
• Vanilla Extract – Rounds out the flavors and enhances sweetness, creating a well-balanced drink.
Step‑by‑Step Instructions for Sugar-Free Keto Eggnog
Step 1: Whisk the Egg Yolks
In a medium bowl, use a handheld mixer or whisk to beat together the egg yolks and erythritol until the mixture becomes light and fluffy, taking about 2 minutes. The color should transform into a pale yellow, indicating air has been incorporated, making the base creamy and luscious for your sugar-free keto eggnog.
Step 2: Heat the Milk Mixture
In a medium saucepan, combine the almond milk (or coconut milk), heavy cream, cinnamon, and nutmeg. Heat over medium heat, stirring gently until the mixture begins to simmer and small bubbles form around the edges, which should take about 5 minutes. Be careful not to let it boil, as you want a warm mixture to blend beautifully with the eggs.
Step 3: Combine the Mixtures
Slowly pour the hot milk mixture into the egg yolk mixture while whisking continuously. This important step, taking about 1-2 minutes, ensures the egg yolks don’t cook too quickly, preventing the eggnog from curdling. The end result will be a smooth, golden liquid that beautifully blends the flavors of your sugar-free keto eggnog.
Step 4: Thicken the Eggnog
Return the combined mixture to the saucepan and cook over medium heat for about 5-7 minutes, stirring constantly until the mixture thickens slightly and coats the back of a spoon. Watch for a gentle simmer, not boiling, as this will maintain the creamy texture reminiscent of traditional eggnog.
Step 5: Strain and Chill
Once thickened, strain the eggnog through a fine mesh sieve into a bowl to remove any potential curdled bits, ensuring a silky-smooth texture. Allow it to cool for a few minutes, then cover and transfer it to the refrigerator to chill for at least 30 minutes, letting the flavors meld beautifully in your rich sugar-free keto eggnog.
Step 6: Add Vanilla and Serve
After chilling, stir in the vanilla extract for that warm, comforting touch. Now, your sugar-free keto eggnog is ready to serve! Pour it into mugs, and feel free to add a dollop of whipped cream or a sprinkle of nutmeg/cinnamon on top for an extra festive flair. Enjoy this creamy holiday delight!
