HOW TO MAKE BOSTON CREAM PIE CROISSANTS:

STEP-BY-STEP INSTRUCTIONS:

Step 1: Make the Pastry Cream
Start by warming up the milk and vanilla extract in a saucepan over medium heat, just until it begins to steam—don’t let it boil. Meanwhile, in a separate bowl, whisk together the egg yolks, sugar, cornstarch, and salt until the mixture turns pale and smooth.

Now slowly pour the hot milk into the egg mixture, whisking constantly to temper the eggs (you don’t want scrambled eggs here!). Once combined, pour the mixture back into the saucepan and cook over medium heat, whisking constantly until it thickens—this should take about 2 to 3 minutes. When it’s ready, the cream should coat the back of a spoon.

Remove from heat and stir in the butter until smooth and glossy. Transfer the pastry cream to a bowl, cover the surface directly with plastic wrap (this prevents a skin from forming), and chill for at least an hour. You can even make it the night before.

Step 2: Slice and Fill the Croissants
Once your pastry cream is nice and chilled, it’s time to prep the croissants. Use a serrated knife to gently slice them in half horizontally, just like you’d cut a sandwich bun. Spoon or pipe a generous amount of pastry cream onto the bottom half of each croissant, then replace the top half.

Step 3: Make the Ganache
Now for the fun part—the chocolate topping. Heat the heavy cream in a small saucepan until it just begins to simmer, then pour it over the chocolate chips in a bowl. Let it sit for a minute, then stir until smooth and velvety.

Step 4: Assemble and Serve
Spoon or drizzle the warm ganache over the tops of the filled croissants. Let it set for a few minutes, or dig in while the chocolate is still gooey. A light dusting of powdered sugar adds a lovely touch if you’re feeling fancy.

HELPFUL TIPS:

  • Use fresh croissants. Day-old croissants can work, but the fresher they are, the better the texture will be—flaky on the outside, soft in the center.

  • Chill the pastry cream thoroughly. This gives it time to firm up so it doesn’t ooze out when you slice into the croissant.

  • Ganache too thick? Add a splash of warm cream to loosen it up.

  • Make it your own. Add a touch of espresso to the ganache or swap in a hint of almond extract in the pastry cream for a unique flavor twist.

FREQUENTLY ASKED QUESTIONS:

Can I use store-bought pastry cream?
Absolutely. While homemade pastry cream adds that extra special touch, store-bought can work in a pinch.

Can I make these ahead of time?
You can assemble them a few hours in advance and refrigerate, but for best texture, add the ganache just before serving.

Can I freeze them?
It’s best not to, as the texture of the pastry cream can change once frozen and thawed. These are meant to be enjoyed fresh!

STORAGE INSTRUCTIONS:

Store any leftover filled croissants in an airtight container in the fridge for up to 2 days. For best results, bring them to room temperature before serving. Avoid microwaving, as it can make the pastry soggy.
