Do you like butter sponge cake? How about chocolate? Rich custard and cream? Do we have just the donut for you! National Boston Cream Pie Day celebrates one of the most divine creations ever to come out of the confectionary field, the Boston Cream Pie. Confession time though! It’s not a pie at all, it’s a cake, and in this case the cake is most definitely not a lie! So if it’s been a while since you’ve last had one of these delightful treats, National Boston Cream Pie Day is your excuse to go out and get a slice of your favorite.
