Can I use boxed cake mix for the layers?

Technically? Sure. But honestly? Don't. The homemade version is so much better, lighter texture, richer flavor, and it's really not much harder than a box mix. If you're pressed for time, bake the cake layers a day ahead and store them wrapped at room temperature.

My custard turned lumpy. What now?

First, don't panic! Strain it through a fine-mesh sieve while it's still warm, this catches any eggy bits. If it's already chilled, whisk vigorously or blend briefly (careful not to overdo it). Next time, remember to whisk constantly while cooking and temper those eggs properly!

Can I make this gluten-free?

Absolutely! Swap the all-purpose flour for a 1:1 gluten-free blend, just make sure it contains xanthan gum. The custard and glaze are naturally gluten-free, so you're golden there.

Why did my glaze crack when I cut the cake?

Ah, the chocolate was probably too cold when you sliced. Let the assembled pie sit at room temp for 20-30 minutes before cutting, that slight softening prevents cracks. Also, use that hot knife trick I mentioned earlier!

Can I freeze assembled Boston cream pie?

I wouldn't recommend it, the custard gets weepy after thawing. Instead, freeze the cake layers separately (wrapped tightly) and make fresh custard when you're ready to assemble. The glaze comes together in minutes anyway!

Help! My glaze won't drip nicely down the sides.

Two likely culprits: either your glaze was too thick (add a teaspoon of warm cream) or your cake layers weren't completely cool (warm cake melts the glaze unevenly). For perfect drips, pour when the glaze is just warm, not hot, and let gravity do its thing.

Can I use milk chocolate for the glaze?

You can, but it'll be much sweeter and won't set as firmly. I prefer bittersweet for that grown-up contrast to the sweet custard. If you must use milk chocolate, reduce the cream to 1/3 cup so it thickens properly.

¾ cup granulated sugar
¼ cup cornstarch
5 large egg yolks (room temperature)
3 tablespoons unsalted butter (cold and cubed)
1 ½ teaspoons vanilla extract

For the Cake:

1 ¾ cups all-purpose flour
1 ¾ teaspoons baking powder
½ teaspoon salt
1 ¾ cups granulated sugar
3 large eggs (room temperature)
2 teaspoons vanilla extract
1 cup whole milk (heated to 165–170°F)

For the Chocolate Glaze:

¾ cup finely chopped bittersweet chocolate (60% cacao)
½ cup heavy cream
1 tablespoon corn syrup
½ teaspoon vanilla extract

Instructions

Make the Pastry Cream: Heat milk until scalding (170-180°F). In a bowl, whisk sugar, cornstarch, and egg yolks. Slowly temper with warm milk, then return to heat and cook, whisking constantly, until thickened. Stir in butter and vanilla. Cover with plastic wrap pressed onto the surface and refrigerate for 2-4 hours.
Make the Cake: Preheat oven to 350°F (175°C). Grease and flour two 9-inch round pans. Whisk flour, baking powder, and salt. Beat eggs, sugar, and vanilla until fluffy. Add warm milk and melted butter, then fold in dry ingredients. Divide evenly and bake for 25-30 minutes. Cool completely.
Make the Chocolate Glaze: Pour hot cream over chopped chocolate and let sit for 2 minutes. Stir until smooth. Add corn syrup and vanilla, then cool slightly until thickened but pourable.
Assemble: Place one cake layer on a plate, spread pastry cream on top, then add the second layer. Pour chocolate glaze over the top, letting it drip down the sides. Chill until set, slice, and serve.

Notes

To prevent lumps in your pastry cream, whisk constantly while cooking and strain it through a fine mesh sieve before chilling.
This ensures a perfectly smooth filling every time!
