How to Make Creamy Vanilla Slice with Flaky Puff Pastry
Step 1: Prepare the Puff Pastry
Preheat your oven to 400°F (200°C). Line two baking trays with parchment paper. Roll out the puff pastry sheets slightly to about 9×9 inches. Prick all over with a fork to prevent puffing during baking. Place the pastry sheets on the trays, then cover with another sheet of parchment and a second tray to weigh them down.
Step 2: Bake the Puff Pastry
Bake for 35-45 minutes or until golden and crisp. Check around the 30-minute mark but allow it to cook until nicely browned. Once done, set aside and let cool completely.
Step 3: Trim the Edges
Using a serrated knife, carefully trim the edges to fit an 8×8-inch square pan. Place this pan on top of one piece of cooked puff pastry and trim around the edges without pressing down.
Step 4: Mix the Dry Ingredients
In a medium saucepan, whisk together ⅔ cup granulated sugar, ½ cup cornstarch, and ¼ tsp kosher salt. Add in 6 large egg yolks and whisk until thoroughly combined.
Step 5: Warm the Milk
In a separate saucepan over medium heat, warm 3½ cups whole milk until it begins to steam. Avoid boiling.
Step 6: Temper the Eggs
Slowly pour in 1 cup of warm milk into the sugar and egg mixture while whisking continuously until fully incorporated. Gradually add this mixture back into the saucepan with remaining milk, whisking until well mixed.
Step 7: Cook, Then Add Butter
Continue cooking over medium heat while whisking constantly until thickened and bubbling—about 5-7 more minutes. Remove from heat and stir in seeds from one vanilla bean along with cold cubed butter until fully blended.
Step 8: Assemble, Then Chill
Line an 8×8 pan completely on all sides with aluminum foil for easy removal later. Place one puff pastry layer at the bottom. Pour warm custard on top—smooth it out using a spatula if needed—then place another piece of pastry over it. Press gently down to adhere before covering tightly with plastic wrap or foil. Chill for at least four hours or overnight.
Step 9: Slice Then Serve!
Gently lift your slice out using foil overhangs. Transfer it onto a cutting board and use a serrated knife to cut into either nine larger squares or sixteen smaller ones. Dust generously with powdered sugar before enjoying!

How to Perfect Creamy Vanilla Slice with Flaky Puff Pastry
Perfecting your Creamy Vanilla Slice with Flaky Puff Pastry requires attention to detail. Here are some handy tips to ensure your dessert turns out flawlessly every time.
- 
Use cold ingredients: Make sure your butter and milk are at the right temperature. Cold butter helps achieve flaky pastry, while warm milk helps temper the eggs properly.
 - 
Whisk constantly: When cooking the custard, whisk continuously to prevent lumps and ensure a smooth texture throughout.
 - 
Bake until golden brown: Keep an eye on your puff pastry as it bakes. It should be golden and crisp, which adds a lovely texture contrast to the creamy filling.
 - 
Chill adequately: Allow sufficient time for chilling after assembly. This helps set the custard and makes slicing easier without mess.

Common Mistakes to Avoid
Making the perfect Creamy Vanilla Slice with Flaky Puff Pastry can be tricky. Here are some common mistakes to watch out for:
- Incorrect Baking Time: Not baking the puff pastry long enough can result in a soggy base. Always check for a golden brown color before removing it from the oven.
 - Not Tempering Eggs Properly: Pouring hot milk directly into cold eggs can cause them to scramble. Always add the warm milk slowly while whisking to keep the mixture smooth.
 - Skipping Cooling Time: Cutting into the slice too soon can lead to messy servings. Make sure to chill it in the fridge for at least 4 hours or overnight for best results.
 - Using Cold Ingredients: Cold ingredients can affect how well the custard thickens. Ensure your milk and eggs are at room temperature before starting.
 - Not Dusting with Powdered Sugar: Forgetting this final touch can make your dessert look less appealing. A light dusting of powdered sugar adds elegance and sweetness.
