Step‑by‑Step Instructions for Creamy Vanilla Slice with Flaky Puff Pastry
Step 1: Prepare Puff Pastry
Preheat your oven to 400°F (200°C) and roll out two sheets of thawed puff pastry to approximately 9×9 inches on a lightly floured surface. Prick the dough with a fork to prevent rising, then cover each sheet with parchment paper and place another baking tray on top. This will keep the pastry flat as it bakes to create a delightful crunch.
Step 2: Bake
Place the prepared puff pastry in the preheated oven and cook for 35-45 minutes, checking for that golden color around the 30-minute mark. The pastry should puff up beautifully and become crisp to the touch when done. Once baked, take them out and allow the pastry sheets to cool completely on a wire rack.
Step 3: Trim Edges
Once the puff pastry has cooled, gently remove it from the baking trays. Use a serrated knife to carefully trim the edges of the baked puff pastry to fit an 8×8 inch pan. This step ensures perfect layering for your creamy vanilla slice, allowing for an even distribution of custard later.
Step 4: Mix Dry Ingredients
In a medium saucepan, combine the granulated sugar, cornstarch, and kosher salt. Whisk these ingredients together until they are well mixed. Then, add the egg yolks to the dry mixture, whisking until the mixture is smooth and homogeneous. This will be the foundation for your rich custard filling.
Step 5: Warm Milk
Pour the whole milk into a separate saucepan and heat it over medium-low until steaming but not boiling, about 5 minutes. Watch closely as you want it to warm through without reaching a boil which could cause the milk to curdle. This step is crucial for creating a creamy texture in your vanilla slice.
Step 6: Temper Eggs
Slowly pour the warm milk into the egg mixture while continuously whisking to avoid scrambling the eggs. Once combined, return the mixture to the saucepan. This gradual process helps to gently cook the eggs and yields a silky custard to complement the flaky puff pastry.
Step 7: Cook Custard
Over medium heat, whisk the mixture continuously until it thickens and bubbles, which should take about 5-7 minutes. You want the custard to be thick enough to coat the back of a spoon. Once it reaches this consistency, add in the scraped vanilla and cold cubed butter, stirring until fully incorporated and smooth.
Step 8: Assemble and Chill
Line your 8×8 inch pan with aluminum foil for easy removal later. Begin by placing one sheet of baked puff pastry at the bottom, then pour the warm custard on top, smoothing it evenly. Place the second layer of pastry on top, cover with plastic wrap, and refrigerate for at least 4 hours, or preferably overnight, to set.
Step 9: Slice and Serve
After chilling, use the edges of the aluminum foil to lift the creamy vanilla slice out of the pan. Trim the edges if desired for a clean look, and dust the top with powdered sugar for that final touch. Slice into squares and serve this delectable treat to your friends and family, savoring each creamy bite!

Expert Tips for the Best Creamy Vanilla Slice
- Temperature Matters: Ensure your egg yolks are at room temperature; this helps them blend smoothly into the custard, creating a better texture.
- Avoid Sogginess: Let your custard cool slightly before pouring it onto the warm puff pastry. This prevents the layers from becoming soggy.
- Keep It Clean: Use a sharp serrated knife to slice the vanilla slice, which will help maintain clean edges and showcase the beautiful layers.
- Be Patient: Chill your assembled vanilla slice for at least 4 hours, or overnight for best results—this allows the custard to set perfectly.
- Check Your Pastry: Ensure your puff pastry is fully baked and golden to achieve that perfect crispy layer that contrasts beautifully with the creamy filling.

Creamy Vanilla Slice with Flaky Puff Pastry Recipe FAQs
How do I choose the best puff pastry for my vanilla slice?
Absolutely! Look for high-quality, all-butter puff pastry as it tends to yield the flakiest layers with a rich flavor. Ensure that the pastry is well-thawed and pliable but not overly sticky. If it has any dark spots or tears, it might not bake as evenly.
How should I store leftover vanilla slice?
Very! Store your vanilla slice in an airtight container in the refrigerator for up to 3 days. It’s essential to keep it sealed to avoid drying out and to maintain the creamy custard’s freshness. Make sure to place parchment between layers to prevent sticking.
Can I freeze creamy vanilla slice? How?
Absolutely! You can freeze individual slices by wrapping them tightly in plastic wrap, followed by aluminum foil. This method prevents freezer burn and keeps the flavors intact. They can be frozen for up to 1 month. To enjoy, simply transfer to the fridge overnight to thaw before serving.
What if my custard doesn’t thicken properly?
Oh no! If your custard doesn’t thicken, it could be due to not cooking it long enough or the heat being too low. Continue whisking over medium heat until you see bubbles, and it coats the back of a spoon. If it’s too thin, whisk in a little cornstarch mixed with cold water into the pot and cook for another minute to improve consistency.
Are there any dietary restrictions I should consider with this recipe?
Very! For those with dairy allergies, you can substitute whole milk with almond or oat milk, though the texture might alter slightly. If you’re accommodating gluten intolerances, look for gluten-free puff pastry options. Always check your ingredients for any allergens, especially for guests or family members with dietary restrictions!
