My father-in-law lives in town, and does a LOT of babysitting for us. He covers the few times during the week that Hubs' schedule and my schedule don't overlap. He loves hanging out with the tyke. They go on lots of walks together, and help each other with small projects around the yard.
FIL's birthday was over Memorial Day weekend. He rented a room at the beach, and invited us over for the day. He also hinted that he would like a Boston cream pie for a birthday cake. I was happy to oblige.

I used the Baker's Illustrated recipe found on
Annie's blog, and the cake was one of the moistest sponge cakes I've ever had. The custard, however, never set and became a runny mess. After reading the comments in the blog post, I guess I didn't cook the custard long enough. I ended up using a Martha Stewart recipe for the custard.
Boston Cream PieCake from
Annies-Eats, originally from Baking Illustrated
Pastry cream from Martha Stewart
Pastry cream:
2 c milk
½ c sugar
4 large egg yolks
2 tsp vanilla extract
Pinch of salt
6 Tbs cornstarch
In a medium saucepan, combine milk and ¼ c of the sugar over medium heat. Bring to a simmer. In a medium bowl, whisk the egg yolks and remaining sugar until well combined. Whisk in vanilla and salt. Whisk in cornstarch, 1 tablespoon at a time, until fully incorporated. Slowly add about 1 cup of the milk mixture to the egg mixture, whisking constantly to prevent the eggs from cooking. Add this back to the saucepan with the remaining milk. Continue cooking over medium heat, whisking constantly, until the mixture comes to a full boil.
Transfer mixture to a medium bowl. Cover with plastic wrap, pressing the wrap against the surface of the filling to prevent a skin from forming. Chill overnight.
Cake:
½ (2 oz)c cake flour
¼ c (1.25 oz) all-purpose flour
1 tsp baking powder
¼ tsp salt
3 Tbs milk
2 Tbs unsalted butter
½ tsp vanilla extract
5 large eggs, room temperature
¾ c (5.25 oz) sugar
Adjust an oven rack to lower-middle position. Preheat oven to 350°F. Line the bottoms of two 8-inch round cake pans with parchment paper. Grease and flour the sides of the pans; set aside.
In a small bowl, whisk together the cake flour, all-purpose flour, baking powder, and salt. In a small saucepan, combine the milk and butter and heat over medium-low heat until the butter melts. Remove from the heat and stir in the vanilla; set aside.
Separate 3 of the eggs, putting the whites in the bowl of a stand mixer. Reserve the 3 yolks plus the other 2 whole eggs in a separate bowl. Fit the mixer with the whisk attachment and beat the whites on low until foamy. Increase the mixer speed to medium and gradually incorporate 6 Tbs of the sugar. Continue beating until the whites form soft, moist peaks. Be careful not to overbeat. Transfer the egg whites to a clean mixing bowl. Add the egg yolk-whole egg mixture to the stand mixer bowl. Beat the egg mixture with the remaining 6 Tbs of sugar at medium-high speed until very thick and pale yellow in color, about 5 minutes.
Add the beaten egg mixture to the bowl of whipped egg whites. Sprinkle the flour mixture over everything in the bowl. Fold very gently with a spatula, about 12 strokes. Make a well in one side of the batter and pour the milk-butter mixture into the well. Continue folding until the batter shows no trace of flour and the eggs are evenly mixed.
Immediately divide the batter between the prepared cake pans. Bake until the tops are light brown and spring back when touched, about 16-17 minutes. Remove pans from oven and run a knife along the edges of the pan to loosen the cakes. Transfer to wire racks by inverting a wire rack onto a cake pan, flipping the pan and rack over, and removing the pan, leaving the cake on the wire rack. Repeat with other cake pan. Cool completely.
Chocolate Glaze:
½ c heavy cream
2 Tbs light corn syrup
4 oz semi-sweet chocolate, finely chopped
¼ tsp vanilla extract
Combine heavy cream and corn syrup in a medium saucepan. Warm over medium heat and bring to a simmer. Remove from heat and add the chocolate. Cover and let stand for 8 minutes. Stir in the vanilla gently until glaze is smooth. Cool until tepid, so that a spoonful of glaze slowly falls back into the pan. You can chill the glaze to speed up this process, stirring every few minutes to ensure even cooling.
To assemble the cake, place one cake layer on a serving plate. Spread custard evenly over the top. Place second cake layer on the cake. Pour glaze in the center of the cake surface. Gently spread the glaze using smooth strokes until the glaze covers the entire top surface of the cake.
