Growing up, this was my favorite dessert. I especially loved it when my mom would get it for me for my birthday. On the last day of culinary school for me I made this in celebration of my accomplishment! Brought me right back to my childhood. Now, with baking I usually have to convert to high altitude and low altitude, but I didn’t for this! The egg whites act as a leavening agent and make the cake airy and fluffy, not at all dense or dry!
Boston Cream Pie
1-9x9 round cake pan
Ingredients
Cake:
1 C plus 2 TBSP cake flour, sifted
⅔ C sugar
1 ½ tsp baking powder
¼ tsp salt
½ C milk
¼ C vegetable oil
2 egg yolks
1 tsp vanilla extract
2 egg whites
¼ tsp cream of tartar
Pastry Cream:
2 C milk
⅓ C sugar
3 egg yolks
2 whole eggs
5 TBSP cornstarch
⅓ C sugar
2 TBSP butter
1 TBSP vanilla extract
Ganache:
1 C semi sweet chocolate chips
1 C heavy cream
Cake:
Preheat oven to 350°F.
In a medium bowl combine flour, sugar, baking powder, and salt. Make a well in the flour mixture. Add milk, oil, egg yolks, and vanilla. Beat on low to medium speed until combined. Increase the speed to high and beat and additional 3 mintues, set aside.
In a large mixing bowl, beat egg whites and cream of tartar on medium speed, increasing to high speed until soft peaks form.
Pour the egg yolk mixture over the egg white mixture and gently fold in. Pour the batter into a 9-inch greased cake pan. Bake for 25 to 30 minutes or until the top springs back and when you insert a toothpick it comes out clean.
Allow to cool completely on a wire rack.
Once cooled, cut in half horizontally.
Pastry Cream:
While your cake is cooling you can make your pastry cream.
Combine milk and first sugar together in a saucepan. Bring to a scald (scald- heating milk to just about boiling).
In a medium sized bowl, whisk the cornstarch and second sugar until combined. Add the yolks and whole eggs and whisk until light in color.
Slowly add the scalded milk and sugar mixture to the eggs and starch mixture, continuing to whisk so that the eggs do not scramble.
Return the mixture to the saucepan and whisk constantly over medium heat until it comes to a boil. Allow to boil for one minute to activate the starch and thicken the custard. Immediately remove from the heat.
Whisk in the vanilla extract and butter.
Pour onto a clean sheet pan and cover with plastic wrap to prevent a skin from forming.
Refrigerate immediately until cool.
Ganache:
Bring heavy cream to a boil in a saucepan. Stir constantly so it doesn't burn on the bottom.
Place chocolate chips in a medium bowl.
Pour hot cream over chocolate chips and let it sit for 5 minutes before stirring.
After 5 minute, whisk to combine and ganache becomes smooth and glossy.
Assembling:
Take one half of the cake and spread cooled pastry cream evenly over the whole half of the cake. Place the other half of the cake on top.
Spread the ganache over the cake.
Refrigerate 20 minutes to allow it to set.
