Ingredients You’ll Need

This recipe pairs buttery puff pastry with a smooth, homemade vanilla custard that sets beautifully. It’s all about balance—the right custard powder and caster sugar create that perfect creaminess, while icing sugar and a hint of water make a glossy, sweet topping that completes the slice wonderfully.

• Puff Pastry Sheets: I prefer thawed puff pastry for easy handling and lovely flakiness after baking.
• Custard Powder: This is key to getting that classic vanilla custard flavor and creamy texture.
• Milk: Whole milk works best to create a rich, luscious custard.
• Caster Sugar: Finely textured so it dissolves fully into the custard without any graininess.
• Icing Sugar Mixture: For the smoothest, sweetest glaze that sets nicely on top.
• Water: Just enough to get the icing to a spreadable consistency.
• Pink Food Colouring (optional): For that nostalgic bakery pink look—you can skip or swap colors as you like.

Variations

I love how versatile this Easy Vanilla Custard Slice Recipe is! Depending on what you have on hand or how adventurous you feel, you can change things up. I’ve experimented a bit, and trust me, every variation brings out a unique but delightful twist.

• Chocolate Drizzle: I once drizzled melted dark chocolate over the pink icing and my family went crazy for the rich flavor contrast.
• Fruit Topping: Fresh berries on top add a nice pop of color and tartness if you want to brighten it up.
• Dairy-Free: Swap regular milk with almond or oat milk and use a dairy-free custard powder to accommodate dietary needs.
• Natural Colouring: Use beet juice or raspberry powder instead of artificial pink food coloring for a natural look.

How to Make Easy Vanilla Custard Slice Recipe

Step 1: Bake the Puff Pastry Layers

Preheat your oven according to the puff pastry package directions, usually around 200°C (400°F). Line a baking tray with parchment paper, lay out your thawed puff pastry sheets, and prick them all over with a fork to prevent excessive puffing. Bake until golden and crisp, about 15-20 minutes. Pro tip: Weigh the pastry down with another baking tray or baking beads if you want a flatter layer, though I like mine puffed for extra texture.

Step 2: Prepare the Vanilla Custard

While the pastry is baking, combine the custard powder and caster sugar in a saucepan. Whisk in a little milk first to make a smooth paste, then gradually add the rest of the milk, stirring continuously. Place the saucepan over medium heat, stirring constantly until the custard thickens and just starts to bubble—this usually takes 5-7 minutes. Don’t rush this part; lumpy custard is the worst. Remove from heat and let cool slightly.

Step 3: Assemble the Layers

Place one of the cooled puff pastry sheets on your serving plate. Spoon and spread the warm custard evenly over it. Then top with the second sheet of pastry, pressing gently down to trap the custard in between. Chill in the fridge for at least 2 hours to let it set properly; this step makes slicing neat and tidy.

Step 4: Make and Spread the Pink Icing

In a bowl, mix the icing sugar with water one tablespoon at a time to get a thick but spreadable consistency. Add 1-2 drops of pink food coloring if using, and mix well. Spread this icing generously over the top puff pastry layer. Smooth it out with a spatula and pop it back in the fridge for about 30 minutes to set the icing.

How to Serve Easy Vanilla Custard Slice Recipe

Garnishes

I often sprinkle a few tiny edible pearls or a dusting of extra icing sugar on top of the set pink icing just for a fancy bakery vibe. Fresh berries like raspberries or strawberries can also add a bright contrast and a hint of tartness that cuts through the sweetness beautifully.

Side Dishes

Pair it with a cup of strong black coffee or your favorite freshly brewed tea—a perfect afternoon treat setup. For a brunch spread, I love serving it alongside fresh fruit salad or a light citrus sorbet to balance the richness.

Creative Ways to Present

For special occasions, I’ve arranged vanilla custard slices on a decorative platter dusted with edible gold leaf or sprigs of fresh mint. Cutting them into smaller bite-sized squares makes for an elegant finger food dessert that’s really fancy but so simple.

Make Ahead and Storage

Storing Leftovers

Once assembled and iced, I cover the tray tightly with plastic wrap and keep leftovers in the fridge. The custard slice holds up well for up to 3 days, though I’d wager your family will finish it quicker than that!

Freezing

Freezing puff pastry custard slices isn’t ideal as the pastry can go soggy after thawing. But if you’re careful and wrap individual slices tightly, you can freeze for up to a month—just expect a slight shift in texture.

Reheating

I don’t recommend reheating as custard is best enjoyed chilled. That said, if you prefer, you can let slices sit at room temperature for 20 minutes before serving to soften the custard slightly.
