What Goes Into Homemade Boston Cream Pie?

While the word ‘pie’ conjures up a different visual, Boston cream pie appears more like a cake. You’ll have to forgive the Bostonians responsible for its creation, for back then, cakes and pies were made in the same pans, resulting in the confusion.

Boston cream pie needs two distinct layers of spongey vanilla cake. It requires a bit of patience as the cake layers have to cool first before the middle layer of rich, creamy custard goes in. And of course, the pièce de resistance, the chocolate ganache, must be poured over to finish it off.

Boston cream pie is a little complex, but we’ve made the recipe easy to follow so you can make it from scratch. It’s an impressive dessert that will surprise and delight your friends and family, so let’s get baking!

Chopnotch Tips

  • Use a mixer to make your cake batter to simplify things and get it blended faster.
  • A fine-mesh strainer is the key to getting the perfect custard filling.
  • You can make the two layers of cake a day or two in advance to save yourself some time. After that, it becomes very easy to assemble your prepared custard.
  • The ganache is best made right before you serve Boston cream pie. If you must make it beforehand, warm it up, and then add it on top just prior to serving.
