In this video, you’ll see how to make vanilla pastry cream and ganache for Boston Cream Pie. If you like, you can use boxed yellow cake mix for the cake itself—because, after all, Boston cream pie is just a pastry cream and ganache delivery system! (It's not actually a pie at all!) Chef John also shows you how to build the “pie,” sandwiching the vanilla pastry cream between two rounds of cake and slowly pouring the chocolate ganache over the top so it slides over the edges here and there. Oh yeah, it’s wicked good! Get the recipe for Chef John’s Boston Cream Pie.
