**Yields:** 10-12 servings
**Prep time:** 45 minutes
**Cook time:** 50-60 minutes

### Ingredients:

**For the Chestnut Puree:**

* 1 pound (450g) fresh chestnuts (or 1 can/jar pre-cooked chestnut puree, about 400g)
* Water (for boiling)
* 1/4 cup milk or cream (optional, for smoother puree)
* 1 tablespoon sugar (optional, to taste)

**For the Cake:**

* 8 ounces (225g) bittersweet chocolate (70% cacao or higher), chopped
* 1 cup (2 sticks or 225g) unsalted butter, softened
* 1 1/4 cups (250g) granulated sugar
* 4 large eggs, separated
* 1 teaspoon vanilla extract
* 1/2 cup (60g) all-purpose flour
* 1/4 teaspoon salt
* 1/4 teaspoon baking powder
* 1/2 cup (50g) unsweetened cocoa powder
* 1/2 cup strong brewed coffee, cooled
* 1/4 cup rum, brandy, or milk (optional, for extra moisture and flavor)

**For the Chocolate Ganache (Optional):**

* 4 ounces (115g) bittersweet chocolate, chopped
* 1/2 cup (120ml) heavy cream

### Equipment:

* Large saucepan (for boiling chestnuts)
* Food processor or potato ricer
* Two 9-inch round cake pans
* Parchment paper
* Mixer (stand or hand-held)
* Spatula
* Wire rack
* Double boiler or microwave-safe bowl

### Instructions:

**Part 1: Preparing the Chestnut Puree (If Using Fresh Chestnuts)**

1. **Score the Chestnuts:** Using a sharp knife, score an “X” on the flat side of each chestnut. This will make them easier to peel after cooking. Be careful not to cut yourself!
2. **Boil the Chestnuts:** Place the scored chestnuts in a large saucepan and cover them with cold water. Bring to a boil over medium-high heat and cook for about 20-30 minutes, or until the shells start to open up and the chestnut meat is tender when pierced with a fork.
3. **Peel the Chestnuts:** Drain the chestnuts and let them cool slightly. While they are still warm (but cool enough to handle), peel off the shells and the thin brown skin underneath. This is easiest to do while they are warm, as the skins tend to stick as they cool.
4. **Puree the Chestnuts:** Place the peeled chestnuts in a food processor and pulse until finely ground. Add milk or cream, if desired, for a smoother puree. You can also use a potato ricer for a finer texture. Add sugar to taste, if desired.

**Part 2: Making the Chocolate Chestnut Cake**

1. **Preheat the Oven:** Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. Line the bottoms with parchment paper circles for easy release.
2. **Melt the Chocolate and Butter:** In a double boiler or microwave-safe bowl, melt the chopped chocolate and butter together, stirring occasionally until smooth. Remove from heat and let cool slightly.
3. **Cream Sugar and Egg Yolks:** In a large bowl, cream together the granulated sugar and egg yolks until light and fluffy. This may take several minutes. The mixture should be pale yellow and significantly lighter in texture.
4. **Combine Wet Ingredients:** Gradually add the cooled chocolate mixture to the egg yolk mixture, mixing until well combined. Stir in the vanilla extract, coffee, and rum or brandy (if using).
5. **Combine Dry Ingredients:** In a separate bowl, whisk together the flour, salt, baking powder, and cocoa powder.
6. **Alternate Wet and Dry Ingredients:** Gradually add the dry ingredients to the wet ingredients, alternating with the chestnut puree. Begin and end with the dry ingredients. Mix until just combined. Do not overmix.
7. **Whip Egg Whites:** In a clean, dry bowl, beat the egg whites with an electric mixer until stiff peaks form. Be careful not to overwhip; the egg whites should be firm but not dry.
8. **Fold in Egg Whites:** Gently fold the whipped egg whites into the batter in two additions. Be careful not to deflate the egg whites, as this will make the cake dense. Use a spatula and a light hand to incorporate the egg whites evenly.
9. **Pour into Pans:** Divide the batter evenly between the prepared cake pans.
10. **Bake the Cakes:** Bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs. The cakes should spring back lightly when touched.
11. **Cool the Cakes:** Let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely.

**Part 3: Making the Chocolate Ganache (Optional)**

1. **Heat the Cream:** In a saucepan, heat the heavy cream over medium heat until it just begins to simmer. Do not boil.
2. **Pour Over Chocolate:** Pour the hot cream over the chopped chocolate in a heatproof bowl. Let it sit for a minute to soften the chocolate.
3. **Stir Until Smooth:** Stir the chocolate and cream together until smooth and glossy. If necessary, gently heat the mixture over a double boiler or in the microwave in short intervals, stirring frequently, until the chocolate is completely melted.

**Part 4: Assembling the Cake**

1. **Level the Cakes (Optional):** If the cakes are uneven, use a serrated knife to level the tops.
2. **Ganache (Optional):** If using ganache, place one cake layer on a serving plate or cake stand. Spread a generous layer of chocolate ganache evenly over the top. Place the second cake layer on top of the ganache.
3. **Dust with Cocoa Powder or Powdered Sugar (Optional):** Dust the top of the cake with cocoa powder or powdered sugar for a simple and elegant finish. Alternatively, you can frost the entire cake with ganache or your favorite frosting.
4. **Serve and Enjoy:** Slice the cake and serve. This cake is delicious on its own or with a dollop of whipped cream, a scoop of vanilla ice cream, or a sprinkle of chopped nuts.

## Tips for Baking the Perfect Chocolate Chestnut Cake

* **Use High-Quality Chocolate:** The quality of the chocolate will significantly impact the flavor of the cake. Choose a bittersweet chocolate with a high cacao percentage (70% or higher) for the best results.
* **Don’t Overmix the Batter:** Overmixing the batter will develop the gluten in the flour, resulting in a tough cake. Mix the wet and dry ingredients until just combined.
* **Gently Fold in the Egg Whites:** Be careful not to deflate the egg whites when folding them into the batter. This will help keep the cake light and airy.
* **Use a Cake Tester:** Use a cake tester or toothpick to check for doneness. Insert it into the center of the cake; if it comes out clean or with a few moist crumbs, the cake is done.
* **Let the Cakes Cool Completely:** Let the cakes cool completely before frosting or serving. This will prevent the frosting from melting and the cake from crumbling.
* **Chestnut Options:** If fresh chestnuts seem daunting, opt for high-quality canned or jarred chestnut puree. Make sure it’s unsweetened or adjust the sugar in the recipe accordingly.
* **Coffee Boost:** The coffee enhances the chocolate flavor. Don’t skip it!
* **Alcoholic Enhancement:** The rum or brandy is optional, but it adds a depth of flavor that complements the chestnut and chocolate beautifully. You can substitute with milk for a non-alcoholic version.

## Variations and Adaptations

* **Add Nuts:** Add chopped walnuts, pecans, or almonds to the batter for extra texture and flavor.
* **Spice it Up:** Add a pinch of cinnamon, nutmeg, or cloves to the batter for a warm, spiced flavor.
* **Citrus Zest:** Add orange or lemon zest to the batter for a bright, citrusy note.
* **Chocolate Chips:** Fold in chocolate chips to the batter for extra chocolatey goodness.
* **Gluten-Free Option:** Substitute the all-purpose flour with a gluten-free flour blend.
* **Vegan Option:** Substitute eggs with applesauce or flax eggs. Use plant-based butter and milk alternatives.

## Storing Your Chocolate Chestnut Cake

* **Unfrosted Cake:** Store the unfrosted cake in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 5 days.
* **Frosted Cake:** Store the frosted cake in the refrigerator for up to 3 days.
* **Freezing:** Wrap the cake tightly in plastic wrap and aluminum foil and freeze for up to 2 months. Thaw overnight in the refrigerator before serving.

## Serving Suggestions

* **With Whipped Cream:** Serve with a dollop of freshly whipped cream.
* **With Ice Cream:** Serve with a scoop of vanilla or chocolate ice cream.
* **With Fruit:** Serve with fresh berries or a compote of cherries or raspberries.
* **With Coffee or Tea:** Enjoy a slice of cake with a cup of coffee or tea.
