Ingredients
Dry Ingredients
- 1 cup almond flour or 3/4 cup all-purpose flour
- 3 tablespoons cornstarch
- 4 tablespoons erythritol or stevia (granulated sugar-free sweetener)
- 1 teaspoon baking powder
- A pinch of salt
Wet Ingredients
- 4 eggs, separated
- 1/2 cup milk or unsweetened almond milk
- 3 tablespoons melted butter
- 1 teaspoon vanilla extract
Directions
1. Prepare the Oven and Pan
Preheat the oven to 160°C (320°F). Line a round or square baking pan with parchment paper to prevent sticking and ensure even baking.
2. Mix the Egg Yolks and Liquid Ingredients
In a medium bowl, combine the egg yolks, sugar-free sweetener, melted butter, milk, and vanilla. Whisk until the mixture becomes smooth and slightly pale.
3. Add the Dry Ingredients
Add the flour of your choice, cornstarch, baking powder, and salt to the yolk mixture. Mix gently until just combined, avoiding overmixing to keep the batter light.
4. Beat the Egg Whites
In a clean, dry bowl, beat the egg whites with an electric mixer until stiff peaks form. The mixture should hold its shape firmly when the beaters are lifted.
5. Fold the Egg Whites Into the Batter
Gently fold one-third of the whipped egg whites into the batter to loosen it. Then fold in the remaining whites carefully using slow, sweeping motions to maintain maximum airiness.
6. Pour and Level the Batter
Pour the batter into the prepared pan and tap it lightly on the counter to release any large air bubbles.
7. Bake to Perfection
Bake for 35–45 minutes, or until the top is golden, the cake is springy to the touch, and a toothpick inserted in the center comes out clean.
8. Cool Slowly
Remove the cake from the oven and let it cool gradually in the pan. Slow cooling prevents the delicate structure from collapsing and keeps the texture light and fluffy.
Tips for Best Results
- Room-temperature eggs whip more easily and give better lift.

- Avoid opening the oven during the first 20 minutes to prevent sinking.

- Allow the cake to cool completely before slicing for clean cuts.

FAQ
1. Is this cake safe for diabetics?
Yes. It contains no added sugar and uses diabetic-friendly sweeteners. Always check with your nutritionist for personal suitability.
2. Can I make this cake with only almond flour?
Yes. Almond flour creates an even softer, lighter texture and keeps the cake lower in carbs.
3. Why did my cake collapse?
Overmixing, opening the oven early, or rapid cooling can cause deflation. Follow the folding method carefully and cool slowly.
4. Can I double the recipe for a larger cake?
Yes. Double all ingredients evenly and add 5–10 minutes to baking time.
