How to Make Creamy Vanilla Slice with Flaky Puff Pastry
-
Preheat Oven: Set your oven to 400°F (200°C) and line two baking trays with parchment paper. This step ensures the puff pastry bakes evenly and doesn’t stick.
-
Prepare the Pastry: Roll out the thawed puff pastry sheets slightly to about 9×9 inches. Prick all over with a fork, then place them on the trays. Cover with another sheet of parchment and weigh down with a second tray for perfect puffing.
-
Bake to Perfection: Bake for 35-45 minutes, or until golden and crisp. Check around the 30-minute mark for that beautiful color, then set aside to cool completely.
-
Trim the Edges: Using a serrated knife, carefully trim the edges of the baked pastry to fit an 8×8-inch square pan, ensuring neat slices later.
-
Mix Dry Ingredients: In a medium saucepan, whisk together ⅔ cup granulated sugar, ½ cup cornstarch, and ¼ tsp kosher salt. This mixture will form the base of your custard.
-
Warm the Milk: In another saucepan, warm 3½ cups of whole milk over medium heat until it begins to steam; keep an eye out – you don’t want it to boil!
-
Temper the Eggs: Slowly pour in 1 cup of the warm milk to the sugar and egg mixture while whisking continuously. Then, gradually mix the tempered egg yolks into the saucepan with the remaining milk until smooth.
-
Cook the Custard: Over medium heat, whisk constantly until the mixture thickens and bubbles, about 5-7 minutes. Once thickened, remove from heat and stir in the vanilla bean seeds and 4 Tbsp cold, cubed butter until perfectly blended.
-
Assemble the Slice: Line the 8×8 pan with aluminum foil, ensuring enough overhang for easy removal. Place a piece of cooked puff pastry on the bottom, pour the warm custard on top, and smooth with a spatula. Press the second pastry on top gently.
-
Chill: Cover tightly with plastic wrap or foil and refrigerate for at least 4 hours or overnight. This chilling time allows the flavors to meld beautifully.
-
Serve with Style: Lift the slice out using the aluminum foil overhang and transfer to a cutting board. Use a serrated knife to cut into 9 larger or 16 smaller squares. Dust generously with powdered sugar before serving.
Optional: Decorate with fresh berries for an extra touch of elegance.

Creamy Vanilla Slice with Flaky Puff Pastry Recipe FAQs
What kind of puff pastry should I use?
Absolutely! You can use store-bought puff pastry sheets for convenience. Just make sure they are fully thawed before rolling out. If you’re feeling adventurous, homemade puff pastry would add a special touch, but it can be time-consuming. Store-bought saves you precious time in the kitchen!
How should I store the creamy vanilla slice?
After preparing your creamy vanilla slice, keep it tightly covered in the fridge. It should stay fresh for up to 3 days. I always suggest using plastic wrap or placing it in an airtight container to maintain its lovely texture and flavor.
Can I freeze this dessert?
Yes, indeed! To freeze your creamy vanilla slice, wrap individual slices in plastic wrap and then place them in an airtight container or a freezer-safe ziplock bag. You can freeze them for up to 2 months. When you’re ready to enjoy, simply thaw overnight in the fridge or leave them at room temperature for a couple of hours. Dust with powdered sugar right before serving to make them extra inviting.
What if my custard doesn’t thicken properly?
If you find your custard isn’t thickening, it may need more heat or whisking time. Be sure to cook it over medium heat and whisk constantly. If you’re faced with a runny custard, you could try adding a bit more cornstarch mixed with a tablespoon of milk to the mixture, then return it to heat while whisking until it thickens. It requires a little patience, but you’ll get there!
Is this dessert suitable for those with allergies or dietary restrictions?
Certainly! This creamy vanilla slice contains dairy and eggs, making it unsuitable for vegans or those with dairy allergies. However, you can explore dairy-free milk alternatives and egg replacements like silken tofu or a commercial egg replacer, but the texture and flavor will differ. Always double-check labels for any potential allergens if you’re serving guests.
How can I customize the flavor of the custard?
The options are endless! For a delightful twist, consider adding a splash of almond extract, citrus zest, or even a hint of coffee to your custard mixture. Be sure to balance it with the vanilla bean for a rich, complex flavor. You could also swap the vanilla bean for other delicious extracts like hazelnut or coconut for a fun variation. Enjoy personalizing your creamy vanilla slice with flaky puff pastry!
