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. Pricking them all over with a fork prevents puffing during baking—this step helps achieve those lovely layers we love! Place the pastry sheets on the trays and cover them with another sheet of parchment and a second tray to weigh them down. If you don’t have enough sheet pans, just repeat as needed.
Step 2: Bake the Puff Pastry
Bake for 35-45 minutes until golden and crisp. It’s important to keep an eye on them after about 30 minutes; we want them beautifully golden brown! Once they’re done, set them aside to cool completely.
Step 3: Trim the Edges
Using a serrated knife, carefully trim the edges of each pastry sheet so they fit an 8×8-inch square pan perfectly. This will help create neat slices later on!
Step 4: Mix the Dry Ingredients
In a medium saucepan, whisk together your granulated sugar, cornstarch, and kosher salt until well combined. Adding your egg yolks next will bring everything together smoothly—this mixture will form our delicious custard base.
Step 5: Warm the Milk
In another saucepan over medium heat, warm your milk until it begins to steam but does not boil. This step ensures that our custard thickens properly when we combine it later.
Step 6: Temper the Eggs
Slowly pour in about one cup of warm milk into your sugar and egg mixture while whisking constantly—that’s key! Gradually add this tempered mixture back into the saucepan with the remaining milk and whisk until fully mixed.
Step 7: Cook, Then Add Butter
Continue cooking over medium heat while whisking constantly until it thickens and bubbles begin to form—this should take around 5-7 minutes. When it’s ready, remove from heat and stir in those lovely vanilla seeds along with cold cubed butter until fully melted and mixed in.
Step 8: Assemble, Then Chill
Line your square pan with aluminum foil so there’s plenty of overhang for easy removal later on. Place one piece of cooked puff pastry on the bottom and pour that luscious warm custard on top—it’s okay if you run it through a sieve first for extra smoothness! Gently press down another piece of puff pastry on top before covering tightly with plastic wrap or foil. Refrigerate for at least four hours or overnight if you can wait!
Step 9: Slice Then Serve!
When ready to serve, gently lift out your slice using that handy foil overhang. Transfer it onto a cutting board and use a serrated knife to cut into squares—scoring first can help make clean cuts. Wipe your knife clean between cuts if you’re aiming for neat slices! Finally, dust generously with powdered sugar before diving in!
And there you have it—a stunning Creamy Vanilla Slice with Flaky Puff Pastry that’s sure to win hearts at any table! Enjoy every decadent bite!
Pro Tips for Making Creamy Vanilla Slice with Flaky Puff Pastry
Making a perfect Creamy Vanilla Slice is all about attention to detail, and I’ve got some tips to help you get that flawless finish!
-
Use cold ingredients: Starting with cold butter and room temperature egg yolks helps create a smoother custard and perfectly flaky pastry. This combination ensures your custard thickens beautifully without curdling.
-
Sift the dry ingredients: Sifting your sugar and cornstarch together eliminates lumps that could affect the texture of your custard. A smooth mixture will yield a creamier final result.
-
Keep stirring: When cooking the custard, constant whisking prevents it from sticking to the bottom of the pan and ensures even cooking. This is vital for achieving that luscious, creamy consistency!
-
Cool completely before slicing: Allow your assembled slice to chill in the fridge for at least 4 hours, or overnight if possible. Chilling helps the layers set, making it much easier to cut clean slices.
-
Score before cutting: Lightly scoring the top pastry can guide your knife when slicing, helping you achieve neat squares without squishing the layers inside.
How to Serve Creamy Vanilla Slice with Flaky Puff Pastry
Presentation is key when serving this delightful dessert! Here are some ideas on how to make your Vanilla Slice look as good as it tastes.

- Mint leaves: A couple of fresh mint leaves can elevate your dish visually while adding a hint of aromatic flavor.
- Chocolate shavings: Lightly sprinkle chocolate shavings on top for an elegant touch that enhances both taste and appearance.
Side Dishes

- Fruit salad: A simple mix of seasonal fruits provides a refreshing contrast to the richness of the Vanilla Slice. Choose vibrant fruits for an eye-catching display!
- Coffee or tea: Serving a cup of freshly brewed coffee or herbal tea alongside your dessert creates a lovely balance and enhances its flavors.
- Ice cream: For an extra treat, serve with a scoop of vanilla or almond milk ice cream. The cold contrast against the creamy slice is simply divine!
