The Most Delicious Boston Creme Pie Cake
There is just something about Boston Creme Pie. I am not sure if it is the combination of the chocolate and creme filling or the ease of making it. Possibly it is the 2 things together. Boston creme “pie” is really a sponge cake. It is named because it turns out as light and fluffy as a sponge. The cake includes two layers filled with a creamy vanilla-flavored custard and topped with rich chocolate icing. Can you say yum? I know I can.

Something tells me that 3/4 cup of kosher salt is going to be overkill!
Oh, Joy that would have been disgusting. Thank you so very much for commenting. I have updated that just now. Kinda like the time my son called and he was making waffles for my grandkids and he thought the recipe said 1/2 cup of baking soda. I said I am sure that has to be wrong. Thank you once again!
