Chocolate Birthday Cake w/ Whipped Ganache Frosting

cake adapted from Alice Medrich’s Bittersweet.

This cake recipe is actually a pound cake recipe that makes the perfect amount of batter for a 6-inch layer cake…which in my opinion, is a great size cake for smaller gathering (in this case, 2 people). The crumb is fantastic, tight and dense without being heavy. The whipped ganache is about as easy as it gets and is perfect for the choco-saurus’ in your life. Use any leftover ganache to roll into light and airy truffles. Another note about this cake, it is best served at room temperature, the frosting and cake will feel dry and hard if served cold–if you make it ahead and refrigerate, just let it sit out on the counter for 30-60 minutes. 

1 cup + 2 Tablespoons sugar

1 cup all-purpose flour

1/2 cup dutch-processed cocoa powder (I used Valrhona)

3/4 teaspoon baking powder

1/4 teaspoon salt

6 Tablespoons room temperature, unsalted butter

2 large eggs + 1 egg white, cold

1 teaspoon instant espresso powder

1 teaspoon vanilla extract

1/2 cup milk

Preheat oven to 350F. Prepare 2, 6-inch round cake pans by buttering and lining bottoms with parchment. Alternatively, butter and flour a 6 cup capacity tube pan.

In a large bowl or the bowl of a mixer, combine sugar, flour, cocoa, baking powder, and salt, stir to combine.

Add the butter, egg, and white. Mix on medium-high for 2 minutes. Scrape bowl as needed. Combine milk, espresso, and vanilla. Add to the batter, mix for 2 minutes, scraping as needed. Scrape the batter into 2, 6-inch cake pans or into a tube pan.

Bake the cakes in the oven for about 25-35 minutes (it may take a little longer in the tube pan). Cool 10 minutes in the pan before unmolding to cool completely on cooling racks.

Once cooled completely, cut the cakes in half to make 4 layers.

Whipped Ganache Frosting

adapted from Martha Stewart.

1 lb. chocolate coarsely chopped, or chips (I used ghiradelli)

2 1/2 cups heavy cream

pinch of salt

Place chocolate and salt in a medium bow or bowl of a mixer, set aside.

In a saucepan, heat heavy cream just to a boil. Remove from heat and pour hot cream over the chocolate. Cover the bowl with a tea towel or plate and let sit for 5 minutes. Whisk ganache until smooth and allow to cool to room temperature.

Beat cooled ganache until fluffy. Use immediately.
