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 helps prevent unwanted puffing during baking. Placing one tray on top of another will keep them flat while they bake.
Step 2: Bake the Puff Pastry
Bake the puff pastry for about 35-45 minutes until golden and crisp. Keep an eye on them starting around the 30-minute mark; they should be beautifully browned and flaky when done. Let them cool completely before moving on.
Step 3: Trim the Edges
Using a serrated knife, carefully trim any uneven edges so that your baked pastry fits perfectly in an 8×8-inch square pan. This step not only tidies up your slice but also ensures even portions when cut later.
Step 4: Mix the Dry Ingredients
In a medium saucepan, whisk together the granulated sugar, cornstarch, and kosher salt. Adding six large egg yolks at this point creates a smooth base for our custard—make sure everything is thoroughly combined!
Step 5: Warm the Milk
In another saucepan over medium heat, warm up your whole milk until it starts steaming but doesn’t boil. This gentle heating helps bring all those lovely flavors together without curdling.
Step 6: Temper the Eggs
Now it’s time to combine everything! Slowly pour one cup of warm milk into your egg mixture while whisking constantly—this technique is called tempering and prevents scrambling. Then gradually add this mixture back into the remaining milk in its saucepan.
Step 7: Cook, Then Add Butter
Continue cooking over medium heat while whisking constantly until it thickens and bubbles—a sign that your custard is ready! Once thickened, remove from heat and stir in those heavenly vanilla seeds along with cold cubed butter until fully melted and mixed in.
Step 8: Assemble, Then Chill
Line your square pan fully with aluminum foil for easy removal later on. Place one piece of cooked puff pastry at the bottom, pour in that luscious warm custard, smoothing it out evenly. Top it off with another piece of pastry before pressing down gently. Cover tightly and refrigerate for at least four hours or overnight if possible; patience pays off!
Step 9: Slice Then Serve!
When you’re ready to enjoy, gently lift out your slice using the foil overhang. Transfer it to a cutting board and use a serrated knife to cut into squares—scoring first can help keep things neat! Dust generously with powdered sugar before serving up this delightful treat!
And there you have it—a beautiful Creamy Vanilla Slice with Flaky Puff Pastry that’s sure to become a favorite in your home! Enjoy every buttery 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 a bit of patience. Here are some tips to ensure your dessert turns out beautifully every time!
-
Use chilled ingredients: Keeping your butter and puff pastry cold helps create that flaky texture we all love. Warm ingredients can lead to a soggier pastry, so make sure everything is nice and chilly!
-
Don’t skip the pricking: Pricking the puff pastry with a fork before baking prevents it from puffing too much. This helps maintain an even layer for your custard filling, ensuring each bite has the right balance of pastry and creaminess.
-
Sift the dry ingredients: Sifting together the sugar, cornstarch, and salt not only removes lumps but also ensures an even distribution of sweetness and thickening power in your custard, resulting in a smoother texture.
-
Be patient while cooking the custard: Cooking the mixture over medium heat and whisking constantly allows it to thicken slowly without burning. Rushing this step can lead to a grainy custard, so take your time for the best results.
-
Let it chill overnight: While you can technically serve it after four hours, letting your vanilla slice chill overnight allows the flavors to deepen and makes slicing easier. Trust me, good things come to those who wait!
