Marble Cake

On some weekends, when I have a little time and need something simple for my morning coffee, I make this marbled cocoa cake. It doesn't require hard-to-find ingredients and, honestly, it mixes quickly if you know the order of the steps. You don't even need a high-performance mixer. I often use regular bowls and a wooden spoon.

Quick Info

Total time: about 1 hour
Preparation time: 15-20 minutes
Baking time: 30-40 minutes
Servings: 10-12 slices (for a 25 cm round pan)
Difficulty: easy
Recipe type: homemade marbled cake, suitable for a snack or dessert

Ingredients

200 ml oil
200 g powdered sugar
100 ml milk
300 g flour
2 tablespoons cocoa
3 eggs
1 teaspoon baking powder
a few drops of vanilla extract
1 teaspoon instant coffee
honey (for serving)

Instructions

1. Separate the eggs. Place the egg whites in a clean bowl and the yolks in another container. It’s easier to do this directly over the sink to avoid waste.

2. Beat the egg whites with a mixer until you achieve a stiff foam. Gradually add the powdered sugar while continuing to mix. In the end, you should have a dense meringue that doesn’t run.

3. Turn off the mixer. Gently fold in the yolks, mixing from the bottom up with a spoon or spatula, not with the mixer. It’s enough to add them one at a time to maintain the volume of the meringue.

4. Gradually add the oil with gentle movements, then the milk. There’s no need to fully homogenize at each step.

5. Next, add the baking powder, then the sifted flour. Mix gently from the bottom up until you obtain a smooth batter.

6. Divide the mixture into two bowls as evenly as possible. In one bowl, add a few drops of vanilla extract and mix briefly.

7. In the other bowl, add the cocoa and instant coffee. The cocoa may seem hard to incorporate; don’t rush, mix well.

8. Grease the baking pan with oil. I always use one with a diameter of 25 cm, as in the recipe, but a regular tray works too if you don’t have a round one.

9. Take a spoonful of each mixture and alternate them in the pan until you finish the batter. A perfect pattern isn’t necessary – the marbling will show when you slice it.

10. Place the pan in a preheated oven at 180°C. Bake for 30-40 minutes until the cake is golden on top and passes the toothpick test.

11. Remove the cake from the oven and let it cool in the pan. Only after it has completely cooled can you take it out and slice it.

12. When serving, drizzle a little honey on top of each slice. The honey melts slightly and adds sweetness without overwhelming the cake.

Why I make this recipe often

It's the kind of cake you can make without much planning since the ingredients are at hand. I love that the result stays fluffy for several days if I keep it covered. It’s not overly sweet, which is perfect for my taste. I can easily adapt it if I want a version without cocoa or if I run out of coffee.

Tips and Variations

Tips

Egg whites really matter – if you don’t beat them enough, it won’t be fluffy.
When adding cocoa, if you see lumps, press them down with the back of the spoon and mix well.
Try not to leave the cake in the oven longer than necessary; it can dry out easily.
Let it cool before removing it from the pan, or it may break.

Substitutions

If you don’t have instant coffee, you can skip it or use regular instant coffee.
Powdered sugar can be replaced with granulated sugar, but it’s a bit harder to beat into the egg whites.
Oil can be substituted with melted butter, but the cake will be slightly denser.
Milk can be plant-based for those avoiding dairy.

Variations

You can add a pinch of cinnamon to the cocoa mixture if you want a slightly different flavor.
If you prefer more cocoa, use 3 tablespoons instead of 2 and reduce the flour a bit.
The honey for serving can be swapped with jam if that’s what you have on hand.

Serving Ideas

It pairs well with coffee or tea.
It can be packed for later since it doesn’t crumble easily.
It’s good on its own, but you can sprinkle a little powdered sugar on top if you don't want honey.

Frequently Asked Questions

Do I have to use a round pan, or can I use a regular tray?
Any pan works, but in a pan that’s too large, the cake will come out thinner and bake faster.

Can I use only cocoa, without instant coffee?
Yes. The coffee adds a subtle flavor, but it’s not essential.

If I don’t have a mixer, can I beat the egg whites with a whisk?
Yes, but it will take longer and you’ll need to ensure you achieve a stiff foam.

Can the cake be frozen?
I don’t recommend it. The texture becomes moist after thawing and it won’t be as good.

How long does it stay fluffy?
If kept covered, it stays good for 2-3 days.

Values may vary depending on the added honey and the size of the eggs.

Storage and Reheating

It can be stored at room temperature, covered, for 2-3 days without issues. It’s best enjoyed at room temperature and doesn’t reheat well; if you want to keep it longer, it’s best to slice it and store it in an airtight container. The cake remains soft if not left uncovered.
