Ingredients

(Makes one 20 cm × 20 cm tray — about 16 pieces)

• 200g digestive biscuits (or Arnott’s Marie biscuits), crushed
• 100g unsalted butter
• 2 tbsp golden syrup (30 mL)
• 200g dark or milk chocolate, chopped
• 200g sweetened condensed milk
• 150g Mint Aero chocolate bars, chopped (plus extra for topping)
• Optional: 50g mini marshmallows or white chocolate chips

Preparation

1: Prepare the Base

1. Line a 20 cm × 20 cm square baking tin with baking paper, ensuring there’s an overhang on the sides for easy removal later.
2. Crush the digestive biscuits into fine crumbs using a food processor or by placing them in a sealed plastic bag and bashing with a rolling pin.
3. In a saucepan over low heat, melt the unsalted butter and golden syrup together, stirring until fully combined.
4. Add the chopped dark or milk chocolate to the saucepan, stirring continuously until the chocolate has melted and the mixture is smooth.
5. Pour in the sweetened condensed milk, mixing well to combine all the ingredients into a cohesive mixture.
6. Remove the saucepan from heat and fold in the crushed biscuits, chopped Mint Aero bars, and, if using, the mini marshmallows or white chocolate chips. Stir until all components are evenly distributed.
7. Transfer the mixture into the prepared baking tin, pressing it down firmly with the back of a spoon to create an even layer.
8. Refrigerate for about 1 hour, or until the base is firm to the touch.

2: Add the Topping

1. Once the base has set, sprinkle additional chopped Mint Aero pieces evenly over the top, pressing them gently into the surface to adhere.
2. Return the traybake to the refrigerator for another 30 minutes to ensure the topping sets properly.

3: Serve

1. Remove the traybake from the tin using the overhanging baking paper and place it on a cutting board.
2. Cut into 16 equal squares using a sharp knife. For cleaner cuts, warm the knife blade under hot water and wipe dry before slicing.
3. Serve chilled or at room temperature, depending on your preference.

Variations

• Mintier Flavor: Add a few drops of peppermint extract to the melted chocolate mixture for an extra minty kick.
• Different Chocolates: Experiment with white chocolate or a combination of dark and milk chocolates for varied flavors.
• Add Crunch: Incorporate chopped nuts like almonds or hazelnuts for added texture.
• Festive Touch: Top with crushed candy canes during the holiday season for a festive appearance and flavor.

Cooking Note

This is a no-bake slice, so while there’s no oven involved, chilling time is crucial. The mixture sets firm thanks to the combination of melted chocolate, condensed milk, and butter, so be sure to allow at least 1–2 hours in the fridge for best results.

To ensure clean slices, let the traybake sit at room temperature for 5 minutes before cutting, and use a hot, dry knife for each slice.

Crushing the biscuits lightly adds texture. You want a mix of fine crumbs and small chunks to keep the base crisp but cohesive.

Serving Suggestions

• Serve chilled with coffee or tea as an afternoon pick-me-up.
• Cut into small squares and include on a dessert platter or party tray.
• Pack into lunchboxes (best with an ice pack) for a sweet surprise.
• Serve with a scoop of vanilla ice cream or mint chocolate chip gelato for an indulgent dessert.
• Stack squares in cellophane bags and tie with ribbon for homemade edible gifts.

Tips

• Use quality chocolate for the best flavour and texture — especially in the topping.
• Avoid overmixing the base mixture once the Aero is added to maintain the bubbly texture.
• Press the base firmly but evenly to help the slice hold together once chilled.
• Store in the fridge in an airtight container for up to 7 days.
• Freeze individual squares for up to 1 month. Defrost in the fridge overnight.
• For a smoother top finish, tap the tray gently on the bench to settle the topping.

Tips

• Storage: Store the traybake in an airtight container in the refrigerator for up to one week.
• Freezing: This traybake freezes well. Wrap individual squares in cling film and store in a freezer-safe container for up to three months. Thaw in the refrigerator before serving.
• Serving Suggestion: Serve with a dollop of whipped cream or a scoop of vanilla ice cream for an indulgent dessert.
