The Parker House Hotel in Boston is credited with inventing this fine dessert. Traditionally, the "pie" is actually white cake with custard (or pastry cream), topped with a chocolate glaze. It's the official dessert of Massachusetts and the Boston Cream donut is the official donut. I couldn't find a Boston Cream Pie recipe that called to me, so I created one using my favorite cake, glaze, and pastry cream recipes. It was a huge hit with my family! If you want Boston Cream Cupcakes, use a pastry bag with tip to inject the cream into the cupcake before glazing. Use Bourbon (Madagascar) vanilla beans for best results. This recipe looks complex, but it's actually pretty easy. Time does not include cooling.
