Chocolate Dump-It Cake by Amanda Hesser - Recipe Print View

Preheat the oven to 375°F, and place a baking sheet on the lowest rack, to catch any drips when the cake bakes. Put the sugar, unsweetened chocolate, butter and 1 cup of water in a saucepan. Place over medium heat and stir occasionally until all of the ingredients are melted and blended. Remove from the heat and let cool slightly. Meanwhile, sift together the flour, baking soda, baking powder and salt. In a small bowl, stir together the milk and vinegar. Grease and flour a 9-inch tube pan. (If you prefer, you can grease it, line it with parchment and then grease and flour it. This is not necessary, but parchment does make getting the cake out easier.) When the chocolate in the pan has cooled a bit, whisk in the milk mixture and eggs. In several additions and without overmixing, whisk in the dry ingredients. When the mixture is smooth, add the vanilla and whisk once or twice, to blend. Pour the batter into the tube pan and bake on the middle rack until a skewer inserted in the center comes out clean, about 30 to 35 minutes. Let the cake cool completely, then remove from the pan and cool on a rack. (This can be tricky – if someone is around, enlist them to help. Place a ring of wax paper on top of the cake so you have something to grab onto when turning it out.) Meanwhile, melt the chocolate chips in a double boiler, then let cool to room temperature. It is very important that the chocolate and sour cream be the same temperature, otherwise the icing will be lumpy or grainy. (Test it by stirring a little of the sour cream and chocolate together in a bowl; if it mixes smoothly, it’s ready.) Stir in the sour cream, 1/4 cup at a time, until the mixture is smooth. Taste some! It’s good. Cut the cake into two layers. Lay the top layer, top-side-down onto a cake plate (or whatever serving platter you like). Spread with icing. Top with the bottom layer, setting the bottom-side-up. This will give you a straighter edge (see photo of finished cake). Ice the top, sides, and center. (If you like a lot of icing, use 2 cups chocolate chips and 2 cups sour cream). My mother uses any leftover icing to make flowers on top. She dabs small rosettes, or buttons, on top, then uses toasted almond slices as the petals, pushing them in around the base of the rosette.
