Step‑by‑Step Instructions for Custard Slice
Step 1: Preheat and Prepare
Start by preheating your oven to 220°C (fan bake). While the oven warms up, grab a 21cm square tin and line it with baking paper—this prevents sticking and makes serving easier. This is the perfect time to prepare your flaky puff pastry, which will create a delightful base for your custard slice.
Step 2: Bake the Pastry Sheets
Take your puff pastry sheets and prick them thoroughly with a fork to prevent puffing up during baking. Place them in the preheated oven and bake for 8 minutes until lightly golden. After this initial bake, press the pastry down using a flat tray to ensure it stays flat and bake for another 8 minutes. Once done, allow the pastry to cool completely on a wire rack.
Step 3: Make the Custard Filling
While the pastry cools, prepare the custard filling. In a mixing bowl, combine custard powder, sugar, vanilla essence, and half of the milk, whisking until smooth. In another bowl, whisk the egg with the remaining milk. This two-step mixing is essential for the creamy texture of your custard slice, so ensure it’s well combined.
Step 4: Cook the Custard
In a saucepan, heat the remaining milk over medium heat until just boiling. Slowly pour in the custard mix while continuously stirring. Cook this mixture, stirring constantly, for about 5 minutes, or until the custard thickens to a creamy consistency. It should be thick enough to coat the back of a spoon, signaling it’s ready for the next step.
Step 5: Combine Ingredients
Remove the saucepan from the heat and gradually stir in the egg mixture and butter into the warm custard. This addition enriches your custard slice, enhancing its silky texture. Mix everything gently for about 2 minutes until the butter melts and the mixture is smooth. Set it aside to cool.
Step 6: Assemble the Custard Slice
Once the custard has cooled, fit one of the baked pastry sheets into the bottom of your lined tin. Carefully pour the cooled custard over the pastry, spreading it evenly. Gently place the second pastry sheet on top, pressing down lightly to secure the layers together. This layering method keeps your custard slice structurally sound.
Step 7: Prepare the Icing
For the icing, in a mixing bowl, combine icing sugar, softened butter, and a splash of hot water. Mix until smooth and creamy. It should be thick enough to spread but not runny. Set aside a small portion to mix with cocoa powder for that delightful chocolate swirl that finishes off your custard slice beautifully.
Step 8: Ice and Decorate
Spread the white icing evenly over the top of your assembled custard slice, ensuring it covers every corner. Take the colored cocoa icing and drizzle it over the top creatively. Use a skewer to make swirling patterns for that artistic touch. This step adds both visual appeal and flavor to your custard slice.
Step 9: Chill Before Serving
Once your custard slice is beautifully decorated, cover it with cling film and refrigerate for at least 5 hours, or preferably overnight. This chilling time allows the flavors to meld and the custard to set perfectly. When ready to serve, use a serrated knife to cut clean slices from your chilled dessert for an impressive presentation.
Make Ahead Options
These Custard Slices are perfect for busy bakers looking to save time during the week! You can prepare the flaky puff pastry and the custard filling up to 24 hours in advance. Simply bake the pastry sheets as directed, allow them to cool, then store them in an airtight container. The custard can also be made ahead; refrigerate it in a separate container to keep it fresh. When you’re ready to assemble, layer the cooled custard between the pastry sheets, ice, and decorate as desired. Allow the assembled slices to chill in the fridge for at least 5 hours (or overnight) for the best results. This approach maintains the creamy texture and delightful flavor of your Custard Slice, all while making weekday dessert prep a breeze!
Expert Tips for Perfect Custard Slice
- Knife Choice: Use a sharp serrated knife to cut the slice, ensuring clean edges and preserving the custard filling without squishing it.
- Pressing Pastry: If the pastry base puffs during baking, press it down gently with a flat tray to achieve an even surface, crucial for layering.
- Custard Consistency: Boil the custard thoroughly while stirring to reach the right thickness; this step is vital for a perfectly creamy texture.
- Warm Custard: Layer the custard while it’s still warm on the pastry; this helps it adhere better, preventing the layers from sliding apart.
- Chill Time: Be patient with chilling; letting the custard slice set overnight enhances flavors and makes slicing easier when serving.

Custard Slice Recipe FAQs
What type of puff pastry should I use?
I recommend using ready-made flaky puff pastry for this Custard Slice; it saves time and provides that delightful light and flaky texture. If you want a completely homemade experience, you can try making your own puff pastry, but it will definitely require more time and effort!
How should I store my custard slice?
Store your custard slice in an airtight container in the refrigerator for up to 5 days. This keeps the pastry from becoming soggy while maintaining the creamy custard filling. Make sure to keep it chilled, as room temperature can lead to a compromised texture.
Can I freeze the custard slice?
Absolutely! You can freeze the uniced custard slice for up to 2 months. Wrap it tightly in plastic wrap to prevent freezer burn. It’s best to wait on the icing until after you’ve thawed it, which you can do overnight in the fridge before serving.
What do I do if my custard doesn’t thicken?
If your custard doesn’t thicken, don’t worry! First, ensure you’re cooking the mixture while stirring continuously—this helps activate the custard powder properly. If it still doesn’t reach the desired thickness, you can simmer it gently for a few more minutes until it coats the back of a spoon. The boiling process is essential, so keep an eye on it!
Can I use almond milk instead of regular milk?
While I typically recommend whole milk for a richer custard, you can substitute almond milk if you prefer a dairy-free option. Just keep in mind that the flavor and texture may be slightly different. For the creamiest results, consider adding a bit of cornstarch to help thicken the custard.
Is this recipe suitable for people with egg allergies?
Since eggs are key for thickening the custard, substituting them entirely may alter the texture significantly. However, you can try using a commercial egg replacer or a mixture of ground flaxseed with water as a substitute. Mix one tablespoon of ground flaxseed with two tablespoons of water and let it sit until it thickens, mimicking an egg’s binding properties.
