History of Boston Cream Pie
The dessert was first created at the Parker House Hotel in Boston in the late 1800s.

How to Make Boston Cream Pie
Step 1: Preparing the Pastry Cream
The first step in making a Boston Cream Pie is preparing the pastry cream. It needs time to chill and set, so make this before you start on the cake.
- Heat the milk until it is just about to boil.
- Whisk the egg yolks, sugar, and cornstarch in a separate bowl until smooth.
- Slowly pour the hot milk into the egg mixture, whisking continuously.
- Return the mixture to the pot and cook over medium heat, whisking until thickened.
- Once thick, stir in the butter and vanilla. Let it cool, and then cover with plastic wrap, placing it in the fridge.

Step 2: Baking the Sponge Cake
- Preheat your oven to 350°F (175°C).
- In a bowl, sift together the flour, baking powder, and salt.
- In a large bowl, beat the eggs and sugar until pale and fluffy.
- Slowly add the sifted flour mixture into the egg mixture and fold gently.
- Heat the milk and butter, then stir it into the batter.
- Pour the batter into a prepared cake tin and bake for about 30 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cake to cool completely before assembling.
Step 3: Making the Ganache
- Heat the cream in a saucepan until steaming but not boiling.
- Pour the cream over the chopped chocolate and let sit for 5 minutes.
- Stir until smooth and glossy. If you prefer an extra shiny ganache, add a tablespoon of corn syrup.
Step 4: Assembling Boston Cream Pie
- Once the cake has cooled, slice it horizontally into two layers.
- Spread the cooled pastry cream on the bottom layer, leaving about an inch from the edges to prevent spilling.
- Place the second layer of cake on top and gently press down.
- Pour the warm chocolate ganache over the top of the cake, letting it drip down the sides for a rustic look.
Place the assembled cake in the refrigerator for at least an hour to set before serving.
Tips for the Perfect Boston Cream Pie
- Use room temperature ingredients for the cake to ensure even mixing and a smooth batter.
- Chill the pastry cream for at least 2 hours before assembling the cake. This helps prevent it from becoming runny.
- For a clean cut, use a warm knife to slice the cake, wiping the blade after each cut.
