Death By Chocolate Cake Recipe

For the Cake:

  1. Prepare Pans: Spray pans with baking spray.
  2. Prepare Cake: Combine all cake mix ingredients until just combine.
  3. Bake: Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Cool.
  4. Cut: Cut domes off cake so they are flat. Slice each cake in half, so you have 4 pieces total.

For the Frosting:

  1.  In a large bowl, cream butter, cocoa powder, and vanilla. Stir in powdered sugar a little at a time. Add heavy cream as needed to reach your desired consistency.

For the Ganache:

  1. In a small sauce pan, heat cream until steaming. Place chocolate chips in a heat proof bowl.
  2.  Pour over chocolate chips. Allow to stand one minute before stirring.

Putting It All together:

  1.  Place approximately 1 cup of frosting on top of the first layer. Spread until smooth. Repeat with remaining layers.
  2. Frost sides and top of cake as well. Place remaining frosting in a piping bag, and set aside.
  3. Place ganache into a squeeze bottle and drip down the sides (I like this tutorial).  Pour remaining ganache onto the center of the top of the cake and spread until smooth.
  4. Pipe remaining frosting around the edges, and top with chocolate curls if desired.

Frequently Asked Questions

How Do I Store Cake?

When you store the cake, be sure to store it in an air tight container. A cake stand with a lid works well.  I store this cake in the fridge to prevent the chocolate ganache from melting.

Can You Freeze Cake?
If the Death By Chocolate Cake is not going to be eaten within three to five days, you can freeze it. If you want to make it in advance the whole cake can be frozen as well.  When you are ready to freeze the Death by Chocolate Cake, you will want to freeze the cake for about 30 minutes before you cover it. Once the frosting and ganache are hard, you can wrap the cake in foil ,or store in an airtight container. This prevents the frosting and ganache from sticking to the plastic. When you are ready to thaw the cake, remove the plastic wrap while it is still frozen.

How Do You Get Smooth Frosting?
To avoid lumps in your frosting, start with softened butter. Also, be sure to use fresh powdered sugar so there are no large lumps. When the butter is softened, beat it until it is light and fluffy. Add in the sugar and liquids slowly to prevent lumps. When frosting the cake use a revolving cake plate with a offset spatula for the best results.
