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; this keeps them from puffing up too much while baking. Place these sheets on your trays and cover them with another sheet of parchment along with a second tray on top as a weight. If you don’t have enough pans, just repeat as needed!
Step 2: Bake the Puff Pastry
Bake those lovely sheets for about 35-45 minutes until they’re golden brown and crisp. I suggest checking them around the 30-minute mark but let them bake until they achieve that beautiful golden color. Once done, set aside to cool completely.
Step 3: Trim the Edges
Using a serrated knife, carefully trim the edges of your baked pastry so they fit perfectly into an 8×8-inch square pan. It helps to place your pan over the pastry without pressing down too hard while trimming around.
Step 4: Mix the Dry Ingredients
In a medium saucepan, whisk together your granulated sugar, cornstarch, and kosher salt until well combined. Then add in those luscious egg yolks and whisk until everything is thoroughly mixed.
Step 5: Warm the Milk
In another saucepan over medium heat, warm up your whole milk until it starts steaming—just don’t let it boil! This step helps bring out the flavors when you mix it into your custard.
Step 6: Temper the Eggs
Now comes an important step—slowly pour in one cup of warm milk into your egg mixture while whisking continuously. This process ensures that we don’t end up scrambling our eggs! Gradually pour this tempered mixture back into the saucepan containing the remaining milk and whisk again until fully integrated.
Step 7: Cook, Then Add Butter
Keep cooking over medium heat while whisking constantly until your mixture thickens and starts bubbling—this usually takes about 5-7 minutes more. Once thickened, remove from heat and stir in those fragrant vanilla bean seeds along with cold cubed butter until fully incorporated.
Step 8: Assemble, Then Chill
Line your square pan completely on all sides with aluminum foil; make sure there’s enough overhang for easy removal later on. Place one layer of cooked puff pastry at the bottom and pour your warm custard on top. Smooth it out evenly using a spatula then gently press down another layer of puff pastry on top. Cover tightly with plastic wrap or foil and refrigerate for at least four hours or overnight.
Step 9: Slice Then Serve!
Carefully lift your chilled slice out using the foil overhang and transfer it onto a cutting board. Use a serrated knife to cut into either nine larger squares or sixteen smaller ones—scoring beforehand can help keep things neat if that’s what you prefer! Dust generously with powdered sugar before serving these delectable treats.
Enjoy every bite of this luscious Creamy Vanilla Slice with Flaky Puff Pastry—it truly is an indulgent dessert that will keep everyone coming back for more!
Pro Tips for Making Creamy Vanilla Slice with Flaky Puff Pastry
Creating the perfect Creamy Vanilla Slice can be a rewarding experience! Here are some pro tips to ensure your dessert turns out beautifully.
-
Use cold ingredients: Starting with cold butter and room temperature egg yolks helps achieve that rich, velvety custard texture. Cold butter emulsifies better, giving your custard a lovely creaminess.
-
Whisk constantly while cooking: This prevents the custard from sticking to the pan and burning. Continuous whisking ensures that the mixture cooks evenly, resulting in a smooth and luscious filling.
-
Sieve the custard (optional): Running your cooked custard through a sieve before pouring it into the pastry removes any lumps, giving you an ultra-smooth texture that’s delightful in every bite.
-
Let it chill overnight: While 4 hours is the minimum chilling time, leaving it overnight allows flavors to meld beautifully and makes slicing easier. The longer chilling time also enhances the overall texture.
-
Use a serrated knife for cutting: A serrated knife allows you to slice through the flaky pastry without squishing it down. Clean cuts make for a more elegant presentation!

- Fresh berries: A handful of fresh raspberries or strawberries adds a vibrant color contrast and a tangy burst of flavor that complements the sweetness of the vanilla slice.

Side Dishes
- Whipped coconut cream: For a dairy-free option, serve your vanilla slice alongside luscious whipped coconut cream. Its lightness balances out the richness of the dessert.
- Citrus salad: A refreshing citrus salad made with orange and grapefruit segments can cut through the sweetness of the slice, offering a zesty contrast that’s delightful.
- Coffee or tea: Pairing your vanilla slice with a strong cup of coffee or herbal tea enhances its flavors and provides a warming balance after a sweet treat.
