From America's Test Kitchen Season 6: German Chocolate Cake
Most German chocolate cake recipes are similar, if not identical, to the one on the German’s Sweet Chocolate box. Our tasters found several shortcomings in this recipe. It produced a cake that was too sweet, with chocolate flavor that was too mild, and with a texture so listless that the filling and cake together formed a soggy, sweet mush. We wanted a cake that was less sweet and more chocolaty than the original, but we didn’t want to sacrifice the overall blend of flavors and textures that makes German chocolate cake so appealing in the first place.
The first order of business was to scale back the recipe by one quarter, which allowed us to fit the batter into two cake pans, thereby producing a cake with four thinner layers rather than three thicker layers. After testing, we discovered that the texture of the cake actually improved when we used whole eggs instead of laboriously separating the eggs, beating the whites, and folding them into the batter. We increased chocolate flavor with a combination of cocoa powder and good-quality semisweet or bittersweet chocolate. By adjusting the level and proportions of the sugar (both brown and white) and butter in the cake and filling, as well as toasting the pecans, we finished the necessary adjustments to create a definitely easier-to-make cake, with better texture and flavor than the original.
Serves 12 to 16
When you assemble the cake, the filling should be cool or cold (or room temperature, at the very warmest). To be time-efficient, first make the filling, then use the refrigeration time to prepare, bake, and cool the cakes. The toasted pecans are stirred into the filling just before assembly to keep them from becoming soft and soggy.
