How to Make 4-Ingredient Baked Cream Custard Cups
This custard is baked gently to achieve a soft, silky texture.
Step 1: Preheat the Oven
Preheat your oven to 325°F (165°C).
Step 2: Mix the Custard
In a bowl, whisk together the eggs, heavy cream, melted butter, and salt until fully combined. Mix gently to avoid adding too much air, which can cause bubbles or a grainy texture.
Step 3: Fill the Cups
Pour the custard mixture evenly into greased ramekins or small oven-safe cups.
Step 4: Bake
Place the ramekins on a baking tray and bake for 40–45 minutes, or until the custards are just set with a slight jiggle in the center.
Step 5: Cool
Remove from the oven and allow the custard cups to cool. They will firm up slightly as they rest.
What Makes This Custard Zero Carb?
This recipe uses only eggs, cream, butter, and salt, all of which contain negligible to zero carbohydrates. Unlike traditional custards that rely on sugar or starch to thicken, this custard sets naturally thanks to the eggs.
Because there are no sweeteners or fillers, the carb count stays as close to zero as possible.
Texture & Flavor
These baked custard cups have a smooth, creamy, flan-like texture with a rich dairy flavor. They’re not sweet, but deeply comforting and satisfying. Many people find that the richness alone makes it feel like a complete dessert.
The butter adds extra silkiness, while the salt balances the creaminess without overpowering the flavor.
Tips for Perfect Custard Cups
Bake low and slow to avoid curdling
Don’t overmix the eggs
Remove from the oven while slightly jiggly
Let cool before serving for best texture
Overbaking can cause the custard to become firm or grainy, so keep an eye on them toward the end.

Warm from the oven

As a dessert or even a breakfast option
They’re especially popular for those following strict zero-carb or carnivore diets.

Custard is best when handled gently to preserve its texture.
