Chocolate Bundt Cake with Sour Cream Chocolate Glaze

I have found my go-to birthday cake. At last. This chocolate cake is ridiculous. You make it in a bundt pan and it’s dark and rich and moist and not too sweet to make room for the dark chocolate glaze, which is more of a pourable frosting, cut with sour cream. I could go on…

Ingredients

For the cake:

  • 1 1/4 cups plus 1 tablespoon brewed coffee
  • 3/4 cup cocoa powder
  • 2 1/4 cups sugar
  • 1 1/4 teaspoons kosher salt
  • 2 1/2 teaspoons baking soda
  • 2 whole eggs
  • 1 egg yolk
  • 1 1/4 cups plus 1 tablespoon buttermilk (You can make buttermilk substitute like I did: put 2 tablespoons white vinegar or lemon juice in a 2 cup measuring cup and fill to the 2 cup line with milk. Let sit for 10 minutes and stir vigorously; use buttermilk amount recipe calls for.)
  • 1 cup plus 2 tablespoons canola oil
  • 1 1/2 teaspoons vanilla extract
  • 2 1/2 cups, plus 2 tablespoons all-purpose flour, sifted
  • undefined

For the glaze:

  • 6 ounces unsweetened chocolate
  • 3/4 cup unsalted butter
  • 3 cups powdered sugar
  • 1/2 cup sour cream, at room temperature (you can substitute Greek-style yogurt)
  • 1/4 cup brewed coffee, cooled
  • undefined

Preparation

Pre-heat the oven to 350°F.  Grease and flour a 10-inch bundt pan.  

To make the cake batter: Put the brewed coffee and cocoa powder in a small saucepan and bring to a boil, whisking frequently. Remove from the heat and let come to room temperature.  

In the bowl of a stand mixer fit with a whisk attachment, mix together the sugar, salt, baking soda, eggs and egg yolk on low speed for about 1 minute. Add the buttermilk, oil and vanilla extract and mix on low again for another minute.  

Add the flour and mix on medium speed for 2 minutes. Add the cooled cocoa mixture and mix on medium speed for 3 minutes. The batter will be very loose. Pour into the prepared cake pan and bake for 1 hour, or until a cake tester inserted in the cake comes out clean.  

Let the cake cool completely in the pan and then invert onto a cooling rack.  

To make the glaze: Chop the chocolate into small pieces; put them in a heatproof bowl (or a double boiler) and set the bowl over a pot of barely simmering water. Be sure that the bottom of the bowl does not touch the boiling water. Remove the bowl from the heat when all of the chocolate bits have melted.  

Melt the butter in the microwave or on the stove. Whisk the melted butter into the melted chocolate until thoroughly incorporated. Sift in half of the powdered sugar. Add the sour cream and whisk to combine. Sift in the remaining powdered sugar and whisk until smooth. The glaze should be thick and shiny. Lastly, add the coffee and whisk to create a glossy glaze.  

Pour the glaze over the bundt cake, covering it completely. Leave at room temperature until ready to serve.
