🧈 Ingredients

For the Biscuit Base

• 7 oz digestive biscuits or graham crackers, crushed
• 7 tbsp unsalted butter, melted

For the Caramel Layer

• 14 oz can sweetened condensed milk
• 7 tbsp unsalted butter
• 1/2 cup light brown sugar
• 2 tbsp golden syrup or corn syrup
• 1/2 cup Biscoff spread

For the Chocolate Topping

• 7 oz milk chocolate, chopped
• 1.75 oz Biscoff cookies, crushed

👩‍🍳 Step-by-Step Instructions

1. Prepare Your Tray

Line an 8×8-inch square baking tray with parchment paper, leaving some overhang so you can easily lift the traybake out once set.

2. Make the Biscuit Base

In a bowl, combine:

• crushed digestive biscuits or graham crackers
• melted unsalted butter

Mix until the texture resembles wet sand.
Press firmly into the bottom of your lined tray using the back of a spoon or the bottom of a flat cup.
Place the tray in the refrigerator to chill while you prepare the caramel.

3. Cook the Caramel

In a medium saucepan, combine:

• sweetened condensed milk
• butter
• brown sugar
• golden syrup

Heat over medium heat, stirring constantly.
Cook for 5–7 minutes, or until the mixture thickens, turns slightly darker, and begins to bubble softly.
Remove the saucepan from the heat and stir in the Biscoff spread until completely smooth and creamy.

4. Layer the Caramel

Pour the warm caramel over the chilled biscuit base.
Use a spatula to smooth the top.
Let the tray cool at room temperature, then place it back into the fridge to firm slightly before adding the chocolate.

5. Melt the Chocolate

Place the chopped milk chocolate in a heatproof bowl. Melt using:

• a microwave in 30-second intervals (stirring between each), or
• a double boiler over gently simmering water

Stir until silky smooth.

6. Add the Chocolate Topping

Pour the melted chocolate over the cooled caramel layer.
Tilt the tray slightly to spread the chocolate evenly, or use an offset spatula for a smooth finish.

7. Add the Biscoff Crumble

Before the chocolate sets, sprinkle the top generously with crushed Biscoff cookies.
Gently press them into the warm chocolate so they stick.

8. Chill and Slice

Refrigerate the traybake for at least 2 hours, or until fully set.
Once firm, lift it out of the tray using the parchment paper and slice into squares using a sharp knife.

Pro tip: Warm the knife under hot water and wipe dry before each cut for clean, neat slices.

🍫 Tips for Perfect Results

• Store in the fridge in an airtight container for up to 5 days.
• Allow the squares to sit at room temperature for 10–15 minutes before serving for the best texture.
• Feel free to swap digestives for graham crackers or any sturdy cookie you like.
• Add a drizzle of white chocolate for contrast or extra flair.
• For texture lovers, mix crushed nuts (pistachios, pecans, or almonds) into the caramel layer.
• Prefer dark chocolate? Swap the milk chocolate topping for a richer, more intense version.
