Step‑by‑Step Instructions for Custard Slice

Step 1: Preheat the Oven
Begin by preheating your oven to 220°C (428°F) on fan bake. While it heats up, take a 21cm square baking tin and line it with baking paper, ensuring it covers the base and sides well to prevent sticking. This will set the stage for our flaky layers of puff pastry in this delightful Custard Slice.

Step 2: Prepare the Pastry
Unfold the defrosted flaky puff pastry sheets and lay them flat on a clean surface. Using a fork, gently prick the pastry all over to prevent bubbling. Place the sheet in the preheated oven and bake for 8 minutes until lightly golden, then press down with another baking tray to flatten it further and bake for an additional 8 minutes. Once done, let the pastry cool completely.

Step 3: Make the Custard Base
In a medium bowl, mix the custard powder, sugar, vanilla essence, and ½ cup of milk until smooth. In a separate bowl, whisk an egg along with another ½ cup of milk until well combined. Having prepared these two, your custard filling for the Custard Slice is almost ready to come together!

Step 4: Cook the Custard
In a large saucepan, heat the remaining 3 cups of milk over medium heat until just bubbling. Slowly stir in the custard mixture and bring it to a gentle boil while continuously stirring. Reduce the heat and let it simmer for about 5 minutes, ensuring it thickens properly. Once thick, fold in the egg mixture and 50g of butter, stirring until fully combined. Allow the custard to cool slightly.

Step 5: Assemble the Custard Slice
Once cool, trim the baked pastry sheets to fit the lined tin. Place one layer at the bottom of the tin and pour the thickened custard over it, spreading it evenly. Gently place the second layer of pastry on top and press down lightly to secure everything together. This assembly will ensure a perfect bite of creamy custard and flaky layers throughout!

Step 6: Make the Icing
In a bowl, combine icing sugar, the remaining 25g of softened butter, and hot water, mixing until smooth and glossy. For a touch of chocolate, take a small portion of this icing and mix in cocoa powder to create a chocolate icing. This will help us adorn our Custard Slice with beautiful swirls for a lovely finishing touch.

Step 7: Decorate the Slice
Once the pastry is set and cool, spread the white icing evenly over the top layer of the Custard Slice. Using a piping bag, drizzle the chocolate icing in lines atop the white icing, and with a skewer, swirl the two together to create a lovely marbled effect. This decorative step will make your dessert visually stunning!

Step 8: Chill and Serve
To let all the flavors meld together beautifully, refrigerate the Custard Slice for at least 5 hours, or ideally overnight. When ready to serve, use a sharp serrated knife to cut neat slices, ensuring the layers stay intact. This chilling process helps to achieve that perfect creamy texture that you and your loved ones will adore!

Custard Slice Recipe FAQs

How do I select ripe ingredients for my Custard Slice?
Absolutely! For the best results, ensure your milk is fresh and not approaching its expiration date. When choosing eggs, look for ones with a clean, un-cracked shell, and a vibrant yolk for rich color. If using vanilla essence, opt for pure extracts to enhance the custard flavor significantly.

What’s the best way to store leftover Custard Slice?
Very! Store your leftover Custard Slice in an airtight container in the refrigerator for up to 5 days. This will help maintain the freshness and creamy texture of the custard. Be sure to keep it covered to prevent drying out and potential absorption of any odors from the fridge.

Can I freeze Custard Slice, and if so, how?
Definitely! To freeze your Custard Slice, wrap individual slices tightly in plastic wrap, then again in aluminum foil. This protects them from freezer burn. The slices can be stored like this for up to 2 months. When you’re ready to enjoy, thaw the slices in the refrigerator overnight. For warming, gently heat them in the microwave for a few seconds to maintain that delightful texture!

What should I do if my custard doesn’t thicken?
Oh no! If your custard doesn’t thicken, it could be due to not reaching a proper boil. To remedy this, ensure you constantly stir while bringing the custard mixture to a boil, and allow it to simmer for the recommended time until it coats the back of a spoon. If it’s still runny, you can try making a slurry by mixing a little custard powder with cold milk and adding it to the mixture, then reheating and stirring until it thickens.

Are there any dietary considerations for this recipe?
Absolutely! If you’re cooking for someone with an egg allergy, you can substitute the egg with a commercial egg replacer or a mixture of flaxseed meal (1 tablespoon of flaxseed meal mixed with 2.5 tablespoons of warm water, let sit for 5 minutes). For lactose intolerance, try using almond milk or coconut milk; however, the creaminess may slightly vary. Be sure to double-check all ingredients for allergens if serving guests!
