The Best 3-Ingredient Low-Carb Baked Egg Custard

Creamy, Dreamy & Guilt-Free (Ready in ~40 Minutes)

This baked egg custard is smooth, rich, lightly sweet (if you want), and naturally low in carbs. It’s perfect for keto, low-carb diets, or a simple high-protein dessert that feels indulgent but stays light.


🧾 Ingredients (Only 3!)

  • 4 large eggs Egg
  • 2 cups heavy cream Heavy Cream
  • ¼ cup low-carb sweetener (monk fruit or erythritol) Erythritol

⭐ Optional Flavor Add-Ins (not required but recommended)

  • 1 teaspoon vanilla extract
  • Pinch of salt (enhances flavor)
  • ½ teaspoon cinnamon or nutmeg

🍳 Step 1: Preheat & Prepare

  1. Preheat oven to 325°F (160°C).
  2. Lightly grease 4–6 ramekins or a baking dish.
  3. Place a kettle of water to heat (for water bath).

🥄 Step 2: Mix the Custard

  1. In a mixing bowl, whisk together:
    • Eggs
    • Heavy cream
    • Sweetener
  2. Whisk until completely smooth (no streaks of egg).

👉 Do not overbeat—just blend well.


🍮 Step 3: Pour Into Ramekins

  1. Divide mixture evenly into ramekins.
  2. Tap lightly to remove air bubbles.

💧 Step 4: Water Bath (Important for Creaminess)

  1. Place ramekins in a deep baking dish.
  2. Carefully pour hot water around them (halfway up the sides).

This prevents curdling and keeps custard silky.


🔥 Step 5: Bake

  • Bake for 35–40 minutes

You’ll know it’s done when:

  • Center is slightly jiggly (not liquid)
  • Edges are set
  • Top is lightly golden

❄️ Step 6: Cool & Set

  1. Remove from oven carefully.
  2. Let cool for 15–20 minutes.
  3. Chill in fridge for best texture (optional but recommended).

🍽️ Serving Ideas

Serve warm or chilled with:

  • Cinnamon dusting
  • Sugar-free whipped cream
  • Fresh berries (low-carb friendly)
  • A drizzle of sugar-free syrup

💡 Pro Tips for Perfect Custard

✔️ Don’t overbake

Overbaking causes a rubbery texture.

✔️ Use a water bath

This is what makes it silky instead of eggy.

✔️ Sweetener choice matters

  • Monk fruit = clean taste
  • Erythritol = slightly cooling aftertaste

✔️ Strain for extra smoothness

For ultra-restaurant texture, pour mixture through a sieve before baking.


🧊 Storage

  • Refrigerator: up to 4 days
