Boston Cream Pie
From Baking Illustrated

1 cup heavy cream
1/4 cup light corn syrup
8 oz semisweet chocolate, chopped into small pieces
1/2 tsp vanilla extract
Pastry Cream, chilled
Foolproof Sponge Cake, baked and cooled

Glaze:

Bring the cream and corn syrup to a full simmer over medium heat in a medium saucepan.
Remove from the heat and add the chocolate; cover and let stand for 8 minutes. (If the chocolate has not completely melted, return the saucepan to low heat; stir constantly until melted.)
Add the vanilla; stir very gently until the mixture is smooth.
Cook until tepid so that a spoonful drizzled back into the pan mounds slightly. (The glaze can be refrigerated to speed up the cooling process, stirring every few minutes to ensure even cooling.)

Cake:

While the glaze is cooling, place one cake layer on a cardboard round on a wire rack set over waxed paper.
Carefully spoon the pastry cream onto the cake and spread it evenly up to the edges.
Place the second cake layer on top, make sure the layers line up properly.
Pour the glaze onto the middle of the top layer and let it flow down the cake sides.
Use a metal spatula, if necessary, to completely coat the cake. Use a small needle to puncture any air bubbles.
Let the cake sit until the glaze fully sets, about 1 hour. Serve the same day, preferably within a couple of hours.

*Note: My experience was more of a Boston Cream Disaster, however I know someone who has used this recipe and had fantastic results.

Pastry Cream
From Baking Illustrated

2 cups half-and-half
1/2 cup sugar
pinch salt
5 large egg yolks
3 tbsp cornstarch
4 tbsp cold unsalted butter, cut into 4 pieces
1 1/2 tsp vanilla extract

- Heat the half-and-half, 6 tbsp of the sugar and the salt in a medium heavy-bottomed saucepan over medium heat until simmer, stirring occasionally to dissolve sugar.
- Meanwhile, whisk the egg yolks in a medium bowl until thoroughly combined.
- Whisk in the remaining 2 tbsp sugar and whisk until the sugar has begun to dissolve and the mixture is creamy, about 15 seconds.
- Whisk in the cornstarch until combined and the mixture is pale yellow and thick, about 30 seconds.
- When the half-and-half mixture reaches a full simmer, gradually whisk the simmering half-and-half into the yolk mixture to temper.
- Return the mixture to the saucepan, scraping the bowl with a rubber spatula; return to a simmer over medium heat, whisking constantly, until a few bubbles on the surface and the mixture is thickened and glossy, about 30 seconds.
- Remove from heat, whisk in the butter and vanilla.
- Strain the pastry cream through a fine-mesh sieve set over a medium bowl.
- Press plastic wrap directly on the surface to prevent a skin from forming.
- Refrigerate until cold and set, at least 3 hours or up to 2 days.

Foolproof Sponge Cake
From Baking Illustrated

1/2 cup plain cake flour
1/4 cup unbleached all-purpose flour
1 tsp baking powder
1/4 tsp salt
3 tbsp milk
2 tbsp unsalted butter
1/2 tsp vanilla extract
5 large eggs, at room temperature
3/4 cup sugar

- Preheat oven to 350F.
- Grease pan and cover bottom with parchment or waxed paper.
- Whisk the flours, baking powder and salt into medium bowl.
- Heat milk and butter in a small saucepan over low heat until the butter melts. Remove from the heat and add vanilla. Cover and keep warm.
- Separate 3 eggs, placing whites in the bowl of standing mixer, reserving the 3 yolks plus the remaining 2 whole eggs in another mixing bowl.
- Beat the 3 whites at low speed until foamy.
- Increase the mixer speed to medium and gradually add 6 tbsp of the sugar; continue to beat the whites to soft, moist peaks. (Do not overbeat.)
- Transfer the egg whites to a large bowl and add the whole-egg mixture to the mixer bowl.
- Beat the whole-egg mixture with the remaining 6 tbsp sugar.
- Beat at medium-high speed until the eggs are very thick and pale yellow color, about 5 minutes. Add the beaten eggs to the whites.
- Sprinkle the flour mixture over the beaten eggs and whites; fold very gently 12 times with a large rubber spatula.
- Make a well in one side the batter and pour the milk mixture into the bowl.
- Continue folding until the batter shows no trace of flour and the whites and whole eggs are evenly mixed, about 8 additional strokes.
- Immediately pour the batter into the prepared cake pans; bake until the cake tops are light brown and feel firm and spring back when touched, about 16 minutes for 9-inch cake pans and 20 minutes for 8-inch cake pans.
- Immediately run a knife around the pan perimeters to loosen the cakes.
- Place one pan on a towel and cover the pan with a large plate.
- Using the towel to protect your hands and catch the cake, invert the pan and remove the pan from the cake.
- Peel off the parchment.
- Reinvert the cake from the plate onto the rack.
- Repeat with the remaining cake. Cool cake layers to room temp before proceeding.
