If you are looking for a very chocolaty experience in cake form, that happens to be easy to make, this Low FODMAP Blackout Cake is the perfect choice. Moist cake with a rich pudding that you use for the filling and the frosting.
For the Pudding: Place the cornstarch in a medium-sized saucepan. In a large measuring cup, combine the milk and cream. Drizzle a few tablespoons of the milk-cream mixture over the cornstarch and whisk until smooth. Pour the remaining milk-cream into the pan, then add sugar, chocolate, and salt. Cook over medium-low heat, whisking often, until the chocolate melts, then watch carefully as you bring it to a gentle boil. Whisk often as it thickens and takes on a pudding-like consistency; it should gently simmer for about 2 to 3 minutes. The pudding should be thick and glossy and leave whisk marks on top.
For the Cake: Position a rack in the middle of the oven. Preheat the oven to 350° F (180°C).
For the Assembly: Have all the components ready to use. Slice both cake layers evenly in half horizontally. Three layers will be used to assemble the cake. The fourth should be crumbled by hand into a bowl along with any scraps; this will be used for the exterior of the cake. Place one cake layer on a serving plate, bottom side down. Cover with a thick layer of pudding, top with the second cake layer and another layer of pudding. Top with the third cake layer, bottom side up. Cover the top and sides generously with pudding, which will be thick enough to stick to the cake. Use your fingers and palms to completely cover the cake top and sides with cake crumbs, pressing them into the pudding to adhere. Refrigerate for at least 2 hours and up to 2 days before serving slightly chilled.
