Boston Cream Pie
The official state dessert of Massachusetts since 1996, this iconic "pie" is actually a cake that originated at Boston's Parker House Hotel in 1856. Two layers of golden sponge cake embrace silky vanilla pastry cream, crowned with a lustrous chocolate ganache.

Tips & Variations
Pastry Cream Perfection
For silkier pastry cream, strain it through a fine-mesh sieve after cooking to remove any lumps. The cream should coat the back of a spoon thickly.
Make Ahead
Pastry cream can be made up to 3 days ahead. Keep plastic wrap touching the surface to prevent a skin from forming. Whisk smooth before using.
Ganache Consistency
If ganache becomes too thick, gently rewarm over a double boiler. For a shinier finish, add an extra teaspoon of corn syrup.
Dark Chocolate Variation
Use bittersweet chocolate (70% cacao) for a more intense, sophisticated ganache that balances the sweet custard beautifully.
Mini Boston Creams
Make cupcake-sized versions by baking in a muffin tin for 18-20 minutes. Fill with pastry cream using a piping bag and dip tops in ganache.
Storage Tips
Store covered in the refrigerator for up to 3 days. The flavors actually improve after a day as they meld together.
