Why You’ll Love This Low Carb Baked Custard
Only Three Main Ingredients
Some desserts require long ingredient lists and specialty items. This recipe keeps things simple. You only need eggs, cream, and sweetener to create a rich, satisfying dessert.

Eggs provide natural protein while adding richness and structure, making this dessert more filling than many traditional sweets.
Perfect for Meal Prep

Customizable
Add spices, extracts, toppings, or flavor variations while maintaining the recipe’s simplicity.
Ingredients
This recipe makes approximately 6 individual servings.
Main Ingredients
4 large eggs
Eggs form the foundation of the custard. They provide richness, texture, and the creamy structure that makes custard unique.
2 cups heavy cream
Heavy cream creates an ultra-smooth, velvety consistency. The higher fat content helps deliver that classic luxurious texture.
1/2 cup granulated sugar substitute
Choose a low-carb sweetener such as:
- Erythritol
- Monk fruit sweetener
- Allulose
- Erythritol-monk fruit blends
Optional Additions
- 1 teaspoon vanilla extract
- Pinch of nutmeg
- Pinch of cinnamon
- Tiny pinch of salt
- Fresh berries for garnish
Equipment You’ll Need
Preparing baked custard requires very little equipment.
- Medium mixing bowl
- Whisk
- Measuring cups
- Individual ramekins or foil tins
- Large baking dish for water bath
- Oven
Using individual baking dishes creates beautiful portion control while helping the custard bake evenly.
Understanding Why Custard Works
Custard may seem fancy, but it’s actually a very simple science.
Egg proteins gently coagulate during baking, creating structure while remaining soft and creamy. Heavy cream adds fat, which contributes to the smooth texture.
The secret is gentle heat.
Bake too hot and the eggs scramble.
Bake slowly and carefully, and you get silky perfection.
That’s why many custard recipes recommend using a water bath—it helps regulate temperature and creates an even cooking environment.
How to Make Low Carb 3-Ingredient Baked Egg Custard
Step 1: Preheat the Oven
Set your oven to:
325°F (165°C)
Lower temperatures help ensure the custard cooks gently and evenly.
Step 2: Prepare the Custard Mixture
Crack the eggs into a medium bowl.
Add the sugar substitute.
Whisk until smooth and fully combined.
Slowly pour in the heavy cream while whisking continuously.
If using vanilla extract, add it now.
Avoid whisking too aggressively because incorporating excess air can create bubbles in the finished custard.
The mixture should appear smooth and creamy.
Step 3: Portion the Custard
Divide the mixture evenly among:
- Ramekins
- Small baking dishes
- Foil tins
- One larger casserole dish
Individual portions generally bake more evenly and look elegant when serving.
Step 4: Create a Water Bath (Highly Recommended)
Place your ramekins inside a larger baking pan.
Carefully pour hot water into the outer pan until it reaches halfway up the sides of the ramekins.
This extra step creates a gentler cooking environment that dramatically improves texture.
Benefits include:
- Smoother custard
- Fewer cracks
- More even baking
- Silkier texture
Step 5: Bake Until Slightly Jiggly
Bake for:
35–45 minutes
You’ll know the custard is done when:
- The edges look set
- The center jiggles slightly
- A knife inserted near the edge comes out mostly clean
Remember: residual heat continues cooking the custard after removal from the oven.
Overbaking is the fastest way to lose creaminess.
Step 6: Cool Before Serving
Remove from oven carefully.
Allow the custards to cool for about 20 minutes.
Serve warm or refrigerate for several hours for a firmer texture.
Chilled custard develops even more flavor.
Tips for Perfect Custard Every Time
Use Room Temperature Eggs
Cold eggs can create uneven mixing.
Allow eggs to sit at room temperature for about 20 minutes before starting.
Strain for Extra Smoothness
For restaurant-quality texture, pour the mixture through a fine mesh strainer before baking.
Don’t Skip Gentle Heat
High heat creates rubbery custard.
Low and slow is best.
Watch Closely Near the End
Every oven behaves differently.
Begin checking around 30 minutes.
Flavor Variations
One of the best things about this recipe is how adaptable it is.
Cinnamon Custard
Sprinkle cinnamon over the top before baking.
Vanilla Bean Version
Use vanilla bean paste for stronger flavor.
Coffee Custard
Add a teaspoon of espresso powder.
Nutmeg Custard
Classic and comforting with warm spice notes.
Citrus Twist
Add a small amount of lemon or orange zest.
Serving Suggestions
This dessert works beautifully in many situations.
Serve Warm For Comfort

Chill for a Firmer Texture
