The cake needs to be refrigerated overnight, and two days is perfect, in order to achieve the best flavor and texture. The sweetener develops as the cake is refrigerated, but if you're not a dark chocolate lover I would recommend adding a little more sweetener. This cake makes three thin layers. Cement them together with my Fudgy Mocha Frosting or 3-4 cups of another low-carb, sugar-free frosting of your choice. THM:S, Low-carb, Sugar free, Gluten/Peanut free (allergy info for cake only)
