## Homemade Torta de Trufa de Chocolate Recipe

**Preparation:** 30 minutes
**Cooking:** 60 minutes
**Servings:** 10 people

### Ingredients

**Chocolate Sponge**

- 3 cups of all-purpose flour
- 3 eggs
- 1 1/2 cups of oil
- 1 1/2 cups of buttermilk
- 1 teaspoon of vanilla
- 1 cup of unsweetened cocoa
- 1 cup of sugar
- 1 teaspoon of baking soda

**Chocolate Truffle**

- 500 g (17.6 oz) of semisweet chocolate
- 300 g (10.5 oz) of heavy cream
- Sprinkles

### Instructions

1. Preheat the oven to 180 C (356 F) for at least 10 minutes. Oil a cake pan about 25 cm (10 in) across, line it with parchment, oil the paper, and dust it with flour or cocoa so the cake does not stick.

1. In a large bowl, whisk the eggs, oil, buttermilk, and vanilla. In a second bowl, combine the sifted flour, baking soda, and cocoa, pour in the wet mixture, and stir well with a spoon.

1. Add all the sugar at once and mix quickly. Pour the batter into the pan and bake for about 1 hour, or until a toothpick inserted in the center comes out clean. Let it cool completely at room temperature before unmolding.

1. Melt the chocolate in a double boiler, heat the cream to just below boiling, add it, let it sit for a couple of minutes, and stir until creamy. Unmold the sponge, cut it into two layers, and fill and cover the cake with the truffle cream. Decorate with sprinkles or chocolate shavings if you like.

## Additional Tips

### Make your own buttermilk

If you do not have buttermilk, add 1 tablespoon of white vinegar to the same amount of whole milk and let it stand for 10 minutes.

### Firmer ganache

Use 250 g of cream instead of 300 g, or chill the ganache longer before spreading.

### Cool completely

Let the sponge cool fully before cutting so the layers do not crumble.

| Original ingredient | Substitute | Ratio | Flavor note |
| --- | --- | --- | --- |
| Semisweet chocolate | Milk chocolate | 1:1 | Sweeter, less intense |
| Buttermilk | Milk with vinegar | 1 tbsp per cup | Same result |
| Oil | Melted butter | 1:1 | Richer, firmer crumb |
| Sprinkles | Chocolate shavings | To taste | More elegant |

## Frequently Asked Questions (FAQs)

### 1. Can I use milk chocolate?

Yes, but the truffle will be sweeter and less intense. You can also combine both types.

### 2. How do I get a firmer texture?

Use less cream (250 g instead of 300 g) or chill the ganache longer before using it.

### 3. How should I store truffle cake?

Keep it refrigerated for up to 4 days, covered with plastic wrap or in an airtight container.

### 4. Why add the sugar last?

Adding the sugar at the end and mixing quickly keeps the batter from being overworked, for a moister crumb.
