Step‑by‑Step Instructions for Irresistible Homemade Vanilla Slice with Flaky Puff Pastry
Step 1: Prepare Puff Pastry
Preheat your oven to 400°F (200°C) and line two baking trays with parchment paper. Roll out the thawed puff pastry sheets on a floured surface until they are about 1/8 inch thick. Prick the pastry all over with a fork to prevent bubbling. This step is crucial to ensuring even baking for your vanilla slice.
Step 2: Bake Puff Pastry
Place the pricked puff pastry on the prepared trays and bake in the preheated oven for 35-45 minutes. The pastry should puff up and turn a beautiful golden brown. Once baked, remove from the oven and let it cool completely on a wire rack. This cooling phase is essential for achieving the perfect flaky layer for your vanilla slice.
Step 3: Trim Edges
Once cooled, carefully trim the baked pastry edges to fit an 8×8 inch pan. Use a sharp knife to create clean lines for a professional look. This step ensures that your layers will fit neatly, giving your vanilla slice an appealing presentation when assembled.
Step 4: Mix Dry Ingredients
In a medium saucepan, whisk together granulated sugar, cornstarch, and a pinch of kosher salt. Stir to combine thoroughly, ensuring there are no lumps. This mixture will form the base of your custard, allowing it to thicken beautifully when combined with the liquids.
Step 5: Warm Milk
In a separate saucepan, heat whole milk over medium heat until it’s steaming but not boiling. Keep an eye on it, as you don’t want it to scorch. This step is important to ensure the milk blends smoothly into the custard mix without clumping, giving your vanilla slice a silky texture.
Step 6: Temper Eggs
In a bowl, whisk egg yolks until smooth. Gradually pour in the warmed milk while continuously whisking, creating a tempered mixture. This process helps prevent the yolks from cooking too quickly, ensuring a velvety custard for your vanilla slice without any scrambled bits.
Step 7: Cook Custard
Return the tempered mixture to the saucepan and cook over medium heat. Stir constantly until the custard thickens and begins to bubble, about 5-7 minutes. When it’s thick enough to coat the back of a spoon, removed from heat and stir in the vanilla seeds and butter until blended.
Step 8: Assemble Dessert
In your trimmed pan, layer one sheet of puff pastry at the bottom. Pour half of the creamy custard over the pastry, spreading it evenly. Place a second layer of puff pastry on top and pour the remaining custard evenly over it, smoothing it out. Chill in the refrigerator for at least 4 hours to set.
Step 9: Slice and Serve
Once set, remove the vanilla slice from the refrigerator. Use a sharp serrated knife to carefully cut it into squares or rectangles for serving. Dust the top with powdered sugar for an elegant finish. Each slice reveals the delightful layers of creamy custard and flaky pastry, ready to be enjoyed!
How to Store and Freeze Vanilla Slice
Fridge: Store your homemade vanilla slice in an airtight container for up to 3 days. This helps maintain its creamy custard and flaky texture.
Freezer: You can freeze individual slices wrapped tightly in plastic wrap and then aluminum foil for up to 2 months. Thaw in the fridge before enjoying for the best experience.
Reheating: If you’d like to warm the dessert slightly, microwave for about 10-15 seconds. This will soften the custard without compromising its quality.
Make-Ahead: Prepare the vanilla slice a day in advance for ease, and store it in the fridge until ready to serve.

Homemade Vanilla Slice Recipe FAQs
What type of puff pastry should I use for the vanilla slice?
Absolutely! For the best results, I recommend using high-quality, store-bought puff pastry that has been fully thawed. This ensures crispiness and convenience, allowing the flaky layers to shine. If you’re feeling adventurous and have the time, homemade puff pastry can also be used, but it does require more effort.
How long does homemade vanilla slice last in the fridge?
The vanilla slice can be stored in an airtight container in the refrigerator for up to 3 days. I recommend enjoying it within this timeframe to relish the delightful contrast between the creamy custard and crisp pastry.
Can I freeze the vanilla slice?
Very! You can absolutely freeze the vanilla slice. Just wrap individual slices tightly in plastic wrap, then in aluminum foil, and freeze for up to 2 months. When you’re ready to enjoy a slice, thaw it in the fridge overnight for the best texture. If you prefer it slightly warmed, a quick zap in the microwave for about 10-15 seconds will do the trick!
What should I do if my custard doesn’t thicken properly?
If your custard isn’t thickening, no need to worry! It may help to increase the heat slightly and continue stirring constantly for a few more minutes. If it’s still too thin after cooking, you can whisk in a slurry made of 1 tablespoon of cornstarch with 1 tablespoon of cold milk. Return it to the heat and cook until bubbling and thickened.
Are there any ingredient substitutions I should consider for dietary restrictions?
Definitely! If you’re looking for a dairy-free option, you can substitute whole milk with almond milk or oat milk, understanding that it may affect the richness. For a vegan option, replace the large egg yolks with aquafaba (the liquid from canned chickpeas) in a 3:1 ratio (3 tablespoons aquafaba for each yolk). Keep in mind, the texture may differ slightly from the original recipe.
