Boston Cream Cruffins
If you are a fan of Boston cream pie, then you will love Boston cream cruffins. They are buttery, flaky pastries filled with luscious vanilla custard and dipped in a rich chocolate ganache- the iconic American dessert in cruffin form. To make this recipe, follow our instructions for homemade cruffins, skipping the final step of coating in cinnamon sugar.
You can prepare the pastry cream and the chocolate ganache up to a few days in advance, or while waiting for the cruffins to proof or bake. If prepared in advance, reheat the ganache briefly before dipping the cruffins.

Ingredients
- 6 homemade cruffins, baked, not coated in cinnamon sugar
Cruffins
- 300g (about 1 ¼ C) Whole milk
- 1/2 Vanilla bean
- 4 Egg yolks
- 77g (¼ C plus 2 Tbsp) Sugar
- 10g (1 tbsp + 1 tsp) Cornstarch
- 10g (1 tbsp + 1 tsp) Flour
- pinch of salt
Pastry Cream
- 100g (about 1 C) Semisweet or bittersweet chocolate, chopped
- 80g (about ⅓ C) Heavy cream
Chocolate Ganache
Instructions
- Make the pastry cream: Add the milk and about half of the sugar (38g) to a medium saucepot. Split the vanilla bean half down the center to expose the inside. Scrape out the seeds and add the seeds along with the pod to the pot of milk. Heat over medium-low heat. Meanwhile, in a medium bowl, whisk together the sugar, cornstarch, flour, and salt. Then add the egg yolks and whisk thoroughly until no lumps remain. Once the milk comes to a gentle boil, remove from the heat and remove the pod. Slowly pour the milk into the egg mixture, whisking continuously. Return the mixture to the saucepot and cook over medium-low heat, whisking continuously until the mix thickens. Once it comes to a gentle boil, continue whisking for 1 more minute. Be careful not to overheat, as it can cause the mixture to curdle. Remove from the heat, pour the custard into the dish, cover with plastic, and refrigerate until cool.
- Make the ganache: Place the chopped chocolate into a small bowl. In a small saucepot, heat the cream over low heat. Once it has just begun to simmer, pour the cream over the chocolate. Allow the mixture to sit for about a minute to melt the chocolate. Whisk until completely smooth and fully incorporated.
- Fill the cruffins: Using a small pairing knife, make a small hole in the top of each cruffin. Fit a piping bag with a long piping nozzle and fill with the pastry cream. Pipe the filling into the top of each cruffin. (You may have some pastry cream leftover.)
- Dip the cruffins: Once all the cruffins are filled, dip the tops in the ganache.
