A cake for chocolate lovers! Death by Chocolate Cake contains four layer of rich chocolate cake frosted with decadent chocolate buttercream and topped with melted chocolate. There is such a thing as too much chocolate on a cake? Impossible. Death by Chocolate Cake This is by far one of the richest, most decadent cakes I’ve ever made. It’s chocolate overload. A dense and fudge-like chocolate cake with chocolate buttercream topped with dark chocolate ganache and decorated with all sorts of chocolates goodies. Since it’s Halloween, I’m calling it Death by Chocolate Cake! Chocolate Fudge Cake Ingredient Notes Unsweetened Chocolate : Also known as Baker’s Chocolate. This ingredient does not have added sugar, it is primarily used in brownies, mousses, and cakes. Unsweetened Cocoa Powder : There are several choices of unsweetened cocoa powder to choose from: natural cocoa, Dutch-processed cocoa, or black cocoa. For this recipe, I used natural cocoa powder from King Arthur Flour. Brown Sugar : Use either light or dark brown sugar. In a pinch, you may use granulated sugar mixed with molasses. See recipe card notes for details. All-Purpose Flour : I exclusively use King Arthur Flour all-purpose flour for consistency. However, any brand will work. For best results, weigh your ingredients using a kitchen scale. If you prefer to use volume measurements (such as cups), use the Stir and Spoon Method to measure flour. Helpful Tools and Equipment This recipe makes two 6-inch cake rounds. Use a sharp serrated cake knife to divide each cake round into two layers. You will end up with a total of four cake layers. A rotating cake turntable is highly recommended for assembling the layer cake. Step by Step Assembly Instructions Place one chocolate cake layer on rotating turn table or cake stand. Add chocolate buttercream. Use a mini offset spatula to spread buttercream into an even layer. Add second cake layer. Repeat spreading buttercream layer. Repeating adding third and fourth cake alternating with buttercream. Spread a thin layer of buttercream to crumb coat the assembled layer cake. Place in the fridge for 15-30 minutes to allow buttercream to harden. Use remaining buttercream to add a thicker coat all over chilled cake. Chocolate Ganache What is ganache? It is a simple mixture of chocolate and heavy cream. Simmered heavy cream is poured over chopped chocolate. The mixture is whisked together until smooth, shiny, and homogenous. Ingredient proportions determine the ganache consistency. This cake uses a one to one ratio of chocolate to cream. It results in a loose ganache perfect for creating chocolate drips. Topping Options This is the fun part! Top the assembled Death by Chocolate Cake with your choice of chocolate cookies, crackers, and candies. Your options and choices are limitless.
