This recipe is featured in Episode 6 of Drunk Dish (Boston Cream Pie & Communism). This is the very recipe first published by Betty Crocker in 1950.
2 large eggs
1 1/2 cups milk
1/3 cup granulated sugar
2 tablespoons cornstarch
1/8 teaspoon salt
2 teaspoons vanilla
Baking spray with flour to grease pan
1 1/4 cups all-purpose flour or 1 1/2 cups cake flour
1 cup granulated sugar
1/3 cup butter or margarine, room temperature
3/4 cup milk
1 1/2 teaspoons baking powder
1 teaspoon vanilla
1/2 teaspoon salt
1 large egg
3 tablespoons butter or margarine
3 oz unsweetened baking chocolate
3 to 4 tablespoons water
1 cup powdered sugar
3/4 teaspoon vanilla
1. Separate the whites and yolks from two eggs. Beat the yolks with a whisk until well mixed. Stir in the milk for the icing.
2. In a saucepan, stir in the rest of the cream filling ingredients(except for vanilla). Add egg mixture gradually. Cook on medium, stirring constantly until it thickens. Boil and stir for 1 minute, then remove from heat and add in the vanilla extract. Chill between 2 and 24 hours.
3. Preheat the oven to 350°F. Spray just the bottom of a 9-inch round cake pan with the baking spray.
4. Mix all ingredients for cake until well-mixed. Pour into cake pans.
5. Bake about 35 minutes. Use the toothpick test. Cool cakes for at least 20 minutes on a cooling rack. Wait another hour or so before frosting.
6. Melt 3 tablespoons butter and the chocolate over low heat, stirring occasionally. In a separate container, heat water. Remove chocolate mixture from heat. Stir in the powdered sugar and 3/4 teaspoon vanilla. Stir in 3 tablespoons hot water. Keep adding water until icing is smooth.
7. This part is tricky. You’ve got to cut the cake horizontally in half. If you have one of those fancy cake cuter things, use it! Otherwise, mark the center with toothpicks around the perimeter of the cake, and use that as a guide while cutting by hand. To split cake horizontally in half, mark middle points around side of cake with toothpicks.
8. Assemble cake as it was cut–with the cut sides on the inside. Spread cream in the middle.
9. Spread glaze to the ends of the cake. Let it drizzle around the edges.
10. Refrigerate whatever you don’t stuff down your gob.
