About the Ingredients

Digestive Biscuits or Graham Crackers

This forms the crunchy base of the traybake, providing a delightful texture that contrasts with the smooth layers above.

Melted Butter

Butter binds the biscuit base together, adding richness and flavor that enhances every bite.

Sugar

A touch of sugar in the base adds a hint of sweetness, balancing the flavors perfectly throughout the dessert.

Unsalted Butter

This is used in the caramel layer, giving it a creamy texture that melts in your mouth.

Brown Sugar

Brown sugar deepens the flavor of the caramel, introducing a hint of molasses that complements the Biscoff spread beautifully.

Sweetened Condensed Milk

This ingredient contributes to the smooth, rich consistency of the caramel, making it luxuriously creamy.

Biscoff Spread (Cookie Butter)

The star of the show! This spread infuses the caramel layer with a unique spiced flavor that is both comforting and indulgent.

Milk Chocolate

This luscious chocolate topping adds a glossy finish and balances the sweetness of the caramel layer.

Tips & Tricks

Chill Your Ingredients

Before beginning, chill your butter and cream to ensure your caramel sets perfectly without becoming too runny.

Use Quality Chocolate

Opt for high-quality milk chocolate for the topping to achieve a smoother melt and richer flavor.

Press Firmly

When creating the biscuit base, press down firmly to prevent it from crumbling when you cut the traybake.

Allow to Set Properly

Be patient! Allow each layer to set in the refrigerator as instructed for the best texture and flavor.

Sharp Knife for Slicing

Use a sharp knife to slice the traybake to ensure clean edges and beautiful squares.

Pro Tips

  • Use Room Temperature Ingredients: Ensure your butter is at room temperature for a smoother caramel layer.
  • Double Boiler Method: When melting chocolate, a double boiler prevents burning and allows for even melting.
  • Experiment with Toppings: Consider adding crushed Biscoff biscuits or nuts on top for added texture.
  • Cutting Technique: For cleaner cuts, run your knife under hot water, then dry it before slicing.

Step-by-Step Instructions

Prepare the Biscuit Base

In a mixing bowl, combine the crushed digestive biscuits, melted butter, and sugar until the mixture resembles wet sand. Press firmly into the base of a lined 9x9-inch traybake tin to form an even layer. Refrigerate for 30 minutes to set.

Make the Caramel Layer

In a medium saucepan over medium heat, melt the butter, brown sugar, and sweetened condensed milk, stirring constantly. Once bubbling, reduce heat and continue stirring for 5–7 minutes until thickened and deepened in color.

Add Biscoff Spread

Remove from heat and stir in the Biscoff spread until smooth. Pour over the chilled base and spread evenly. Refrigerate for at least 1 hour to set the caramel layer.

Melt the Chocolate

Melt the milk chocolate and Biscoff spread together using a double boiler or microwave in short intervals, stirring frequently until smooth.

Final Assembly

Pour the melted chocolate mixture over the set caramel layer and spread evenly with a spatula. Refrigerate for 2 hours, or until fully set.

Delicious Variations

Nutty Delight

Add chopped nuts, such as hazelnuts or walnuts, to the caramel layer for an extra crunch and nuttiness.

Fruit Twist

Layer sliced bananas or strawberries on top of the chocolate for a fresh and fruity contrast.

Spicy Kick

Incorporate a pinch of sea salt or a sprinkle of cayenne pepper in the chocolate layer for an unexpected spicy twist.

Freezer

Wrap individual squares tightly in plastic wrap and store in a freezer-safe container for up to 3 months.
