Diabetic-Friendly Fail-Proof Egg Custard Bars
Diabetic-Friendly Fail-Proof Egg Custard Bars
Low carb • Sugar-free baked egg custard squares — 25 minutes, nine bars
These are diabetic-friendly fail-proof egg custard bars, not a sugar-set flan. Eggs, cream, allulose, and a dust of nutmeg bake into a pale square with a gold top, like the slice on the spatula. Twenty-five minutes. No sugar, no crust.
Nine bars. Bake until the center barely jiggles. Cool before you cut or the square smears.
Why you’ll love these bars
- 4g protein per bar — eggs and cream

Health notes
- Protein: Modest. These are custard bars, not a shake.
- Lower carb than sugar custard: Eggs, cream, and allulose. Close to keto-zero at 2g net.
- Nine bars: Macros are per square, not the pan.
- Sugar or a flour crust will jump the carbs. Keep it crustless.
Key element — gentle bake, just-set center, cool before you cut
A hard bake makes rubber. Whisk eggs with cream and allulose until smooth. Pour into a small dish, dust nutmeg, and bake until the edges are set and the center barely jiggles. Cool so the square lifts clean, like the photo.
Ingredients
Bars (9)
- 4 large eggs
- 1 1/2 cups unsweetened almond milk or half cream, half unsweetened almond milk
- 1/3 cup heavy cream
- 1/3 cup powdered allulose
- 1 tsp vanilla extract
- Pinch of salt
- 1/4 tsp ground nutmeg or cinnamon, for the top
- Butter, for the dish
Swaps
- All cream: Use 1 3/4 cups cream for a richer square.
- Cinnamon only: Dust the top if you are out of nutmeg.
- Sugar or a wheat crust: Skip them. That is how carbs jump.
Instructions
| 1 | Heat. Heat oven to 325 F (165 C). Butter an 8×8 dish. |
| 2 | Whisk. Whisk eggs, almond milk, cream, allulose, vanilla, and salt until smooth. Do not beat in extra air. |
| 3 | Pour. Pour into the dish. Dust nutmeg on top. |
| 4 | Bake. Bake 15 to 18 minutes until the edges are set and the center barely jiggles. |
| 5 | Cool. Cool 20 minutes, then chill 30 minutes if you want clean squares, like the photo. Cut 9 bars. One bar is one serving. |
Pro tips
- 325 F, not 400. A hot oven curdles the eggs.
- Stop when the center still has a slight jiggle. Overbaked custard is rubber.
- Cool before you cut. Hot custard smears on the spatula.
- Powdered allulose. Granules stay gritty.
- A water bath is optional. This shallow dish sets without one if the oven stays moderate.
