Smart Cake

The first time I made the smart cake, I was a bit skeptical about the final texture. The mixture before baking looked more like a thin soup than the classic cake batter. However, the result is exactly as it should be – three distinct layers, with a dense cream in the middle. I liked that it doesn’t require a lot of dishes or special techniques, and if you follow the steps, it comes together on its own in the oven.

Quick Info

Total time: about 1 hour and 30 minutes
Preparation time: 20-30 minutes (depending on how quickly you move)
Baking time: 1 hour
Servings: 10-12, depending on the size of the pieces
Difficulty: medium
Recipe type: homemade dessert, suitable for occasions

Ingredients

8 eggs
300 g sugar
2 packets of vanilla sugar
2 tablespoons of water
250 g butter
225 g flour (ideally sifted)
1 liter of lukewarm milk
zest of one lemon (or to taste)
a pinch of salt
powdered sugar for finishing

Instructions

1. Prepare the butter. Cut the butter into pieces and melt it over low heat or in the microwave. Once melted, let it cool to room temperature.

2. Separate the eggs. Place the yolks in a large bowl. Keep the egg whites separate for later.

3. Beat the yolks. Add the sugar, vanilla sugar, and the two tablespoons of water to the yolks. Mix everything for a few minutes until the sugar starts to dissolve and the mixture becomes creamy.

4. Incorporate the butter. Pour the melted and cooled butter over the yolk mixture. Mix well until combined.

5. Add the flour. Gradually incorporate the sifted flour, mixing after each addition to avoid lumps. In the end, you should have a smooth mixture.

6. Pour in the milk. Add the lukewarm milk (not hot) in a thin stream while continuously stirring. The mixture will thin out significantly, which is normal. Also, add the grated lemon zest.

7. Prepare the egg whites. In a separate bowl, beat the egg whites with a pinch of salt until you achieve a firm but not dry foam. This step should be left for last to prevent the foam from deflating.

8. Incorporate the egg whites. Gently fold the egg white foam into the mixture with yolks and milk. Mix lightly with a whisk or spatula, just enough to distribute the egg whites throughout the mixture. You don't need to fully homogenize it, as the layers form precisely because of this difference in texture.

9. Prepare the baking pan. Line a baking pan with parchment paper. Pour the mixture into the pan. The consistency should be liquid, which is how it should be.

10. Bake the cake. Place the pan in the preheated oven at medium heat (about 170°C, if you need a reference). Bake for 1 hour. In the end, the edges should be slightly golden, and the center should feel firm to the touch but not dry.

11. Cool and portion. Let the cake cool completely in the pan, then dust with powdered sugar. It cuts best after sitting in the refrigerator for at least a few hours.

Why I make this recipe often

I love it because it doesn’t involve many complicated steps. The ingredients are easy to find. You don’t need experience for it to turn out well if you follow the steps in order. Plus, the texture, with the cream layer in the middle, is something special compared to other quick cakes. It holds up well the next day, if there’s any left.

Tips and Variations

Tips

- Beat the egg whites only at the end, just before incorporating them.
- Use milk at room temperature or slightly warm, not cold from the fridge.
- Don’t over-mix after adding the egg whites – the differences in density help form the layers.

Substitutions

- The lemon zest can be replaced with torn or crushed mint leaves for a different flavor.
- Vanilla sugar can be substituted with vanilla extract.

Variations

- For an extra flavor boost, add a tablespoon of vanilla or orange liqueur to the milk.
- You can use whole or semi-skimmed milk; the result will be slightly different in density.

Serving Ideas

- The smart cake is served cold, cut into squares. It can be enjoyed plain or with a little powdered sugar on top.
- It’s perfect as a dessert at the table or with coffee.

Frequently Asked Questions

Should the cake mixture be liquid before baking?
Yes, before placing the pan in the oven, the mixture is very fluid, almost like a soup. During baking, the cake will settle into layers.

What happens if I don’t beat the egg whites well?
Insufficiently beaten egg whites won’t provide volume, and the layers won’t form correctly. It’s important for them to be a firm foam but not dry.

Why do layers sometimes not form?
Possible causes include: the oven being too hot, the egg whites being over-mixed into the mixture, or the milk being too cold.

Can I make the cake with whole wheat flour?
I wouldn’t recommend it, as the texture will be denser, and it may alter the structure of the layers.

What type of pan is suitable?
Ideally, a classic rectangular pan lined with parchment paper. Avoid using pans with removable bottoms, as the mixture is too liquid.

Nutritional Values

Approximately, per serving (out of 12):
Calories: 300-340 kcal
Protein: 6-8 g
Carbohydrates: 35-40 g
Fats: 16-18 g

The values are indicative, depending on how much cake is cut per serving and the type of milk or butter used. It’s a rich dessert, with many eggs and sugar, making it quite energizing.

Storage and Reheating

The smart cake is best stored in the refrigerator, covered, for up to 3 days. I don’t recommend reheating it – it’s served cold, and the cream maintains its consistency and flavor. If left at room temperature for too long, it may release some liquid. The safest way is to cut it and keep it portioned to avoid it falling apart when removed from the pan.
