Ingredients

⅔ cup granulated sugar (130g)
¼ teaspoon fine sea salt
¼ cup cornstarch (30g)
6 egg yolks (at room temperature)
2 cups whole milk, divided (510g)
3 tablespoons unsalted butter (40g)
2 teaspoons vanilla extract (8g)
1 ½ cups all purpose flour (185g)
1 ½ teaspoons baking powder (7g)
¾ teaspoon fine sea salt (4.5g)
3 large eggs (at room temperature)
1 ½ cups granulated sugar (300g)
1 ½ teaspoons vanilla extract (6.5g)
¾ cup milk (180g)
6 tablespoons unsalted butter (85g)
½ cup heavy cream (120g)
2 tablespoons corn syrup (41g)
5 ounces bittersweet chocolate (142g)

Instructions

Step 1: In a medium heatproof bowl, whisk together the granulated sugar, salt, and cornstarch. Add the 6 egg yolks and ¼ cup of the whole milk, mixing until smooth. Set aside.
Step 2: Heat the remaining 1 ¾ cups whole milk in a saucepan over medium heat until it just begins to simmer. Remove from heat.
Step 3: Temper the egg yolk mixture by slowly pouring about ½ cup of the hot milk into it while whisking constantly. Then pour the tempered egg mixture back into the saucepan with the remaining hot milk, whisking continuously.
Step 4: Return the saucepan to medium heat and cook, stirring constantly with a wooden spoon, until the mixture thickens and bubbles, about 5 minutes.
Step 5: Remove from heat and stir in 3 tablespoons of unsalted butter and 2 teaspoons vanilla extract. For smooth pastry cream, strain through a fine mesh sieve. Cover with plastic wrap touching the surface and refrigerate for at least 2 hours.
Step 6: Preheat the oven to 325°F. Prepare two 9-inch cake pans by spraying with non-stick spray and lining with parchment rounds, then spray the parchment.
Step 7: In a small bowl, whisk together flour, baking powder, and salt. Set aside.
Step 8: In a large bowl or mixer, beat eggs with 1 ½ cups sugar for 4 minutes until the mixture falls from the beater like a slow ribbon.
Step 9: Mix in 1 ½ teaspoons vanilla extract.
Step 10: Gradually add the flour mixture, mixing on low speed until combined.
Step 11: In a microwave-safe container, combine ¾ cup milk and 6 tablespoons butter; heat until butter melts and milk steams. Slowly add this to the batter, mixing on low until just combined. The batter will be runny.
Step 12: Divide the batter evenly between the prepared pans and bake for 28–33 minutes, until a toothpick inserted in the center comes out clean.
Step 13: Let cakes cool in pans for 20 minutes, then run a knife around edges and invert onto wire racks. Cool completely.
Step 14: Remove pastry cream from the fridge about 20 minutes before assembling to soften slightly.
Step 15: Place one cake layer on a serving plate. Spread the pastry cream over it, leaving a ½-inch border around the edges.
Step 16: Top with the second cake layer, bottom side up, and gently press down to spread the cream evenly. Refrigerate while preparing ganache.
Step 17: For the chocolate glaze, heat heavy cream and corn syrup in a microwave-safe bowl until steaming. Stir in chopped bittersweet chocolate, let sit 5 minutes, then stir until smooth.
Step 18: Pour the glaze over the cake, spreading evenly and allowing some to drip down the sides. Chill the cake for at least 2 hours to set.
Step 19: Before serving, let the cake sit at room temperature for about 30 minutes. For clean slices, use a knife dipped in warm water and wipe between cuts.

Tips & Variations

For an extra smooth pastry cream, be sure to strain it after cooking to remove any lumps.
Use a kitchen scale when dividing batter for perfectly even cake layers.
If you prefer, substitute some whole milk with cream in the pastry cream for a richer filling.
Leftover chocolate glaze can be stored and used as a decadent topping for ice cream or pancakes.

Storage

Store the assembled Boston Cream Pie in the refrigerator, covered, for up to 3 days. Allow it to return to room temperature for about 30 minutes before serving for the best texture and flavor. Leftover cake can also be wrapped tightly and frozen for up to 1 month; thaw in the refrigerator overnight before enjoying.

How to Serve

The image shows a round, two-layer cake on a white cake stand with a smooth, shiny dark chocolate glaze dripping evenly down the sides. The cake itself is golden brown with a thick layer of light yellow cream filling sandwiched between the two layers, visible through the sides. The shiny chocolate glaze on top contrasts with the soft texture of the cake and cream inside. In the background, there is a blurred white cup of tea or coffee and another white container, all placed on a white marbled surface. A purple cloth is draped casually on the surface near the cake stand, and some pieces of dark chocolate are scattered nearby. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I make the pastry cream ahead of time?

Yes, pastry cream can be made up to 24 hours in advance. Cover it tightly with plastic wrap touching the surface to prevent a skin from forming, then refrigerate until ready to use.

What is the best way to get clean slices on this cake?

Use a sharp knife dipped in warm water before slicing. Wipe the blade clean between each cut to keep slices neat and prevent the chocolate glaze from smearing.
