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. Placing the pastry sheets on trays and covering them with another sheet of parchment along with a second tray helps keep them flat while baking.

Step 2: Bake the Puff Pastry

Bake for about 35-45 minutes or until golden brown and crisp. It’s essential to keep an eye on them after around the 30-minute mark! Once they’re golden, set aside and let them cool completely.

Step 3: Trim the Edges

Using a serrated knife, carefully trim the edges of the pastry so they fit perfectly into an 8×8-inch square pan. This step ensures that each slice looks neat and tidy when served!

Step 4: Mix the Dry Ingredients

In a medium saucepan, whisk together the granulated sugar, cornstarch, and kosher salt. Add in those luscious egg yolks and whisk until everything is well combined. This mixture is key for creating that smooth custard texture.

Step 5: Warm the Milk

In another saucepan over medium heat, warm your whole milk until it starts steaming—but don’t let it boil! This step helps integrate flavors without curdling your custard.

Step 6: Temper the Eggs

Now comes the fun part! Slowly pour in one cup of warm milk into your egg mixture while whisking continuously. This gradual process prevents scrambling the eggs. Then gradually whisk this mixture back into the saucepan with the remaining milk.

Step 7: Cook, Then Add Butter

Keep cooking over medium heat while constantly whisking until it thickens and bubbles—about 5-7 minutes more! Remove from heat and stir in vanilla seeds along with cold cubed butter until melted. This makes your custard rich and creamy!

Step 8: Assemble, Then Chill

Line your square pan’s bottom and sides with aluminum foil for easy removal later. Place one piece of puff pastry at the bottom then pour that fabulous warm custard on top—smooth it out evenly! 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.

Step 9: Slice Then Serve!

Once chilled, gently lift out your delightful slice using the foil overhang. Transfer to a cutting board and use a serrated knife to cut into squares—either larger or smaller depending on your preference! Dust generously with powdered sugar before serving.

Enjoy every bite of this irresistible Creamy Vanilla Slice with Flaky Puff Pastry!

Pro Tips for Making Creamy Vanilla Slice with Flaky Puff Pastry

Making a perfect Creamy Vanilla Slice can be a delightful endeavor, and these tips will help you succeed with ease!

  • Use cold ingredients: Make sure your butter and egg yolks are at the right temperature. Cold butter ensures a flakier pastry, while room-temperature egg yolks blend better into your custard.

  • Whisk constantly: When cooking the custard, keep whisking to prevent lumps and ensure even cooking. This helps achieve that smooth, velvety texture we all love in a vanilla slice.

  • Chill thoroughly: Allow the dessert to chill for at least 4 hours or overnight if possible. This helps the layers set properly and makes slicing easier.

  • Sift powdered sugar: When dusting your finished slices, use a fine sieve to sprinkle powdered sugar evenly over the top. This not only looks beautiful but also prevents clumping.

  • Experiment with flavors: Feel free to infuse other flavors into your custard, such as lemon zest or almond extract, for a fun twist on the classic vanilla flavor.

How to Serve Creamy Vanilla Slice with Flaky Puff Pastry

Presenting your Creamy Vanilla Slice can be just as enjoyable as making it! Here are some ideas to make it look spectacular on your table.

Garnishes

  • Fresh berries: A handful of strawberries or blueberries on the side adds a pop of color and freshness that complements the creamy texture.

  • Mint leaves: A few sprigs of fresh mint not only enhance presentation but also provide a refreshing contrast to the rich custard.

Side Dishes

  • Whipped coconut cream: Light and fluffy coconut cream serves as a dairy-free alternative that pairs beautifully with this dessert. It’s creamy yet light enough not to overpower the vanilla slice.

  • Fruit salad: A simple mix of seasonal fruits can add a burst of freshness and acidity that balances the sweetness of the slice perfectly.

  • Chocolate sauce: Drizzling some dairy-free chocolate sauce offers a luscious contrast to the cool, creamy layers of the slice—a true indulgence!
