How to Make Boston Cream Cake
- Bake cake as directed on box. Grease and flour the bottom only of a 13 x 9 inch pan. Pour cake into prepared pan and bake according to directions.
- When cake is done baking, cool on rack for 5 minutes. Meanwhile, prepare the pudding as directed on the box. With the handle of a wooden spoon, poke many holes in the warm cake. Spread all the pudding over the cake with a spatula, carefully pressing the pudding into the holes. You will still have a layer of pudding on top of the cake. Cover and refrigerate for at least an hour.
- Uncover the container of chocolate frosting. Microwave for approximately 20 seconds. Stir well and pour over the pudding layer. Spread to the edges and refrigerate another hour before serving.
