Ingredients

• 1.75 cups all-purpose flour
• 2 cups granulated sugar
• 0.75 cups unsweetened cocoa powder (Dutch-processed preferred)
• 1.5 teaspoons baking powder
• 1.5 teaspoons baking soda
• 1 teaspoon salt
• 2 eggs (large)
• 1 cup whole milk
• 0.5 cups vegetable oil
• 2 teaspoons pure vanilla extract
• 1 cup boiling water
• 8 ounces dark chocolate (chopped, for ganache)
• 1 cup heavy cream (for ganache)
• 1 tablespoon unsalted butter (optional, for ganache)

Directions

Step 1

Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans or line them with parchment paper circles.

Step 2

In a large mixing bowl, sift together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.

Step 3

Add the eggs, milk, oil, and vanilla extract to the dry ingredients. Mix using a hand or stand mixer on medium speed until well combined, about 2 minutes.

Step 4

Reduce the mixer speed to low and carefully add the boiling water to the batter. The batter will be thin—this is normal.

Step 5

Divide the batter evenly between the prepared pans. Bake in the preheated oven for 30–35 minutes, or until a toothpick inserted into the center of the cakes comes out clean.

Step 6

Let the cakes cool in the pans for 10 minutes, then remove them from the pans and transfer to a wire rack to cool completely.

Step 7

To make the ganache, place the chopped dark chocolate in a heatproof bowl. Heat the heavy cream in a small saucepan over medium heat until it just begins to simmer (do not boil).

Step 8

Pour the hot cream over the chocolate and let it sit for 2 minutes. Stir gently until the chocolate is fully melted and the ganache is smooth. If desired, stir in 1 tablespoon of butter for added gloss.

Step 9

Set the ganache aside to cool at room temperature until it thickens to a spreadable consistency, about 20–30 minutes.

Step 10

Once the cakes are completely cool, place one layer on a serving plate. Spread a generous amount of ganache on top. Place the second cake layer on top and spread the remaining ganache over the top and sides of the cake.

Step 11

Slice and serve the cake. Store any leftovers in an airtight container at room temperature for up to 2 days or in the refrigerator for up to a week.
