- 2 cups (480ml) whole milk
- 1/2 cup (100g) granulated sugar
- 4 large egg yolks
- 3 tablespoons cornstarch
- 1 tablespoon unsalted butter
- 2 teaspoons vanilla extract
- Pinch of salt
For the Chocolate Glaze
- 1/2 cup (85g) semi-sweet chocolate chips
- 1/4 cup (60ml) heavy cream (or whole milk)
- 1 tablespoon butter (optional, for extra shine)
Optional toppings:
- Chocolate sprinkles
- Powdered sugar dusting
Preparation Time
- Prep time: 20 minutes
- Cooking time: 10 minutes (pastry cream)
- Bake time: 28–35 minutes
- Chill time: 45–60 minutes (for best slicing)
- Total time: About 2 hours
Step-by-Step Instructions
Step 1: Make the Pastry Cream
In a saucepan, warm milk until steaming (not boiling).
In a bowl, whisk sugar, egg yolks, cornstarch, and salt until smooth. Slowly whisk in warm milk.
Return mixture to the saucepan and cook over medium heat, whisking constantly, until thick (about 4–6 minutes).
Remove from heat and stir in butter and vanilla.
Cover with plastic wrap directly on the surface and chill while you prep the loaf.
Step 2: Prep the Pan
Preheat oven to 350°F (175°C). Grease a 9×5-inch loaf pan and line with parchment (optional but helpful).
Step 3: Layer the Croissant Dough
Unroll crescent dough and press seams together to form flat sheets.
Place one sheet in the bottom of the loaf pan, allowing dough to slightly climb the sides.
Spread half of the chilled pastry cream evenly over the dough.
Add a second layer of dough, then spread the remaining pastry cream.
Top with the final layer of dough (use extra dough scraps to cover gaps if needed).
Brush the top lightly with melted butter.
Step 4: Bake
Bake for 28–35 minutes, until puffed and deep golden brown.
If the top browns too quickly, tent with foil for the last 8–10 minutes.
Step 5: Cool and Chill
Cool loaf in the pan for 20 minutes, then lift out and cool completely.
For clean slices, chill the loaf for 45–60 minutes before glazing and slicing.
Step 6: Make the Chocolate Glaze
Heat cream until hot (microwave 30–45 seconds). Pour over chocolate chips and let sit 1 minute.
Stir until smooth. Add butter if using for extra shine.
Drizzle glaze over the loaf and let set for 10–15 minutes.
Step 7: Slice and Serve
Slice into thick pieces and enjoy the flaky layers, creamy vanilla filling, and chocolate topping.
Serving Suggestions
- Serve chilled for the cleanest slices and “Boston cream” donut vibe.
- Pair with coffee or espresso for a true Dunkin-style treat.
- Add fresh strawberries or raspberries to balance the richness.
- Warm slices slightly and spoon extra pastry cream on top.
- Make it dessert-ready with a scoop of vanilla ice cream.

- Want extra flakiness? Use croissant dough sheets if you can find them.
