Ingredients

For the Biscuit Base:

400g (14oz) digestive biscuits or graham crackers
200g (7oz) unsalted butter
200g (1 cup) dark chocolate chips
100g (1/2 cup) milk chocolate chips
3 tablespoons cocoa powder
100g (1/2 cup) granulated sugar
60ml (1/4 cup) milk

For the Caramel Layer:

400g (14oz) store-bought caramel sauce or dulce de leche
1/2 teaspoon sea salt (optional, for salted caramel flavor)

For the Topping:

150g (1 cup) mixed nuts (walnuts, hazelnuts, peanuts)
100g (1/2 cup) caramel chips or butterscotch chips
4 tablespoons caramel sauce (for drizzling)
50g (1/4 cup) dark chocolate, melted (for drizzling)

Instructions

Prepare the pan: Line an 8-inch (20cm) square cake pan or dish with parchment paper, leaving some overhang for easy removal later.
Crush the biscuits: Place the digestive biscuits or graham crackers in a large zip-top bag and crush with a rolling pin until you have a mixture of fine crumbs and small chunks. Alternatively, pulse in a food processor, being careful not to make the crumbs too fine – some texture is desirable.
Make the chocolate mixture: In a large saucepan over low heat, melt the butter, both chocolate chips, cocoa powder, sugar, and milk, stirring constantly until smooth and fully combined.
Combine with biscuits: Remove from heat and fold in the crushed biscuits, making sure all pieces are well coated with the chocolate mixture.
Create the first layer: Transfer about 2/3 of the chocolate biscuit mixture to the prepared pan, pressing down firmly and evenly with the back of a spoon or flat-bottomed glass to create a compact base.
Add the caramel layer: If using store-bought caramel sauce, warm it slightly for easier spreading. Pour and spread the caramel evenly over the biscuit layer. If adding salt for a salted caramel flavor, sprinkle it over the caramel now.
Top with remaining mixture: Crumble the remaining 1/3 of the chocolate biscuit mixture over the caramel layer, creating a rougher, more textured top surface.
Add nuts and chips: Scatter the mixed nuts and caramel chips over the top, gently pressing them into the surface.
Drizzle with toppings: Warm the additional caramel sauce slightly and drizzle over the top of the cake. Follow with drizzles of melted dark chocolate for a decorative finish.
Chill to set: Refrigerate the cake for at least 4 hours, preferably overnight, until completely set and firm.
Serve: Remove from the refrigerator 15-20 minutes before serving to take the chill off. Lift out using the parchment paper overhang, cut into squares, and enjoy!

Cooking Tips and Tricks

Biscuit selection matters: While digestive biscuits or graham crackers are traditional, you can experiment with other crisp cookies like shortbread, Biscoff, or even chocolate sandwich cookies (remove cream filling first).
Texture balance: For the perfect texture, aim for a mix of fine crumbs and small chunks when crushing your biscuits. This creates both structure and satisfying texture.
Chocolate melting technique: When melting the chocolate mixture, use low heat and stir constantly to prevent scorching. If you have a double boiler, even better.
Easy release: The parchment paper sling is crucial for easy removal. Make sure it extends up all sides of the pan with some overhang to use as handles.
Caramel consistency: If your store-bought caramel is too thick to spread, warm it slightly in the microwave (10-15 seconds), or stir in 1-2 tablespoons of heavy cream to thin it.
Neat cutting: For clean slices, dip your knife in hot water and wipe dry between cuts. This melts through the chocolate slightly for smoother edges.
Proper setting: Resist the temptation to cut the cake too soon. Proper chilling is essential for the layers to set and hold together when sliced.
Temperature tip: Taking the cake out of the refrigerator 15-20 minutes before serving allows flavors to bloom and textures to soften slightly for the best eating experience.

Variations and Substitutions

Cookie variations: Try using chocolate digestives, gingersnaps, Biscoff cookies, or Oreos (with filling removed) for different flavor profiles.
Chocolate options: Experiment with different chocolate combinations like all dark for intensity, all milk for sweetness, or add white chocolate for visual contrast.
Nut-free version: Replace nuts with additional biscuit pieces, mini marshmallows, or dried fruit for a nut-free alternative.
Boozy twist: Add 2-3 tablespoons of Baileys, Kahlúa, or rum to the chocolate mixture for an adult version.
Flavor enhancements: Add 1 teaspoon of instant coffee powder to the chocolate mixture for a mocha flavor, or 1/2 teaspoon of cinnamon for warmth.
Fruit additions: Layer in dried cranberries, cherries, or chopped dried apricots for fruity bursts of flavor.
Vegan adaptation: Use dairy-free chocolate, plant-based butter, and coconut condensed milk caramel for a vegan version.
Layered approach: Create more distinct layers by adding a middle layer of white chocolate ganache or peanut butter between the biscuit and caramel layers.

Common FAQs

Q: Can I make this cake ahead of time?

A: Absolutely! This cake actually improves with time as the flavors meld together. You can make it up to 3 days in advance and keep refrigerated.

Q: My cake didn’t set properly. What went wrong?

A: The most common cause is not chilling it long enough. Make sure to give it at least 4 hours, preferably overnight. Another possibility is that the chocolate mixture was too runny—ensure you use the correct proportions of ingredients.

Q: Can I freeze this cake?

A: Yes! This cake freezes beautifully. Wrap it well in plastic wrap and then aluminum foil, and freeze for up to 3 months. Thaw overnight in the refrigerator before serving.

Q: The caramel layer is oozing out when I cut the cake. How can I prevent this?

A: Make sure your caramel layer is completely set before cutting. Additionally, using a slightly thicker caramel or adding 1 tablespoon of butter to your caramel will help it set firmer.

Q: Can I use homemade caramel instead of store-bought?

A: Definitely! If making homemade caramel, cook it to a slightly thicker consistency than you would for a sauce, so it sets properly in the cake.
