Step‑by‑Step Instructions for Coffee Slice
Step 1: Prepare the Baking Tin
Begin by greasing and lining a 20 x 20 cm baking tin with parchment paper, allowing some overhang for easy removal later. This crucial step will ensure that your delicious Coffee Slice releases smoothly once set, giving you a beautiful presentation for serving.
Step 2: Crush the Biscuits
Using a food processor or a sturdy rolling pin, crush the Arnott’s Marie biscuits into fine crumbs. Aim for a texture similar to sand, which will create a solid base for your Coffee Slice. This should take about 3-5 minutes, ensuring all pieces are uniformly crushed for even mixing.
Step 3: Mix Coffee Mixture
In a small bowl, combine the instant coffee granules, cocoa powder, light brown sugar, and boiling water. Stir until all the ingredients are fully dissolved, forming a smooth coffee mixture. This step brings forth the rich flavor profile that will permeate your Coffee Slice, so take a moment to ensure everything is well blended.
Step 4: Combine Base Ingredients
In a large mixing bowl, combine the crushed biscuits, sweetened condensed milk, desiccated coconut, melted butter, vanilla extract, and the previously prepared coffee mixture. Stir with a wooden spoon or spatula for about 2-3 minutes until everything is thoroughly mixed and forms a sticky, cohesive mixture that will serve as the base of your slice.
Step 5: Press into Tin
Transfer the mixture into the prepared baking tin, spreading it evenly across the bottom. Use the back of a spoon or your hands to press down firmly, ensuring the base is compact and smooth. This step is essential for achieving a well-structured Coffee Slice that holds together beautifully when served.
Step 6: Make Icing
In a microwave-safe bowl, melt the milk chocolate and additional salted butter together at 30-second intervals, stirring in between until the mixture is smooth and shiny. Once melted, stir in instant coffee until well combined. This creamy chocolate icing will add the perfect finishing touch to your Coffee Slice.
Step 7: Ice the Slice
Once the base has cooled slightly, carefully spread the chocolate icing evenly over the top, ensuring every edge is covered. Use a spatula to create a smooth layer that will set to a glossy finish. This irresistible topping will enhance the flavor and appearance of your delightful Coffee Slice.
Step 8: Chill
Finally, place the entire tin into the refrigerator for at least 2 hours to allow the Coffee Slice to set completely. This patience pays off as chilling solidifies the base and icing, creating a decadent treat that’s easy to slice and serve when you’re ready to enjoy!

Coffee Slice Recipe FAQs
How do I select the right biscuits for the Coffee Slice?
For the best texture and flavor, use Arnott’s Marie biscuits, as they provide the right structure. If you can’t find them, don’t worry! Digestive or rich tea biscuits are excellent substitutes that will still hold up beautifully in the recipe.
What is the best way to store leftover Coffee Slice?
Store the Coffee Slice in an airtight container in the refrigerator for up to 5-7 days. This will help maintain its delicious texture and flavor. Make sure to keep it well-covered to prevent it from drying out.
Can I freeze the Coffee Slice, and how?
Absolutely! For longer storage, slice the Coffee Slice into portions and wrap each piece in plastic wrap. Place them in a freezer-safe container or bag and store for up to 2 months. When you’re ready to enjoy, simply thaw in the refrigerator for several hours or at room temperature for about 30 minutes.
What should I do if my Coffee Slice is too crumbly or falls apart?
This can happen if the base mixture isn’t packed down tightly enough or if there is too much dry ingredient. To troubleshoot, after mixing your base, press it down firmly into the tin. If it’s still crumbly after chilling, I recommend adding a bit more melted butter or sweetened condensed milk next time to help bind it better.
Are there any dietary considerations for this recipe?
Yes! The Coffee Slice contains gluten from the biscuits and dairy from the butter and condensed milk. For gluten-free options, look for gluten-free biscuits. If you’re lactose intolerant, consider using dairy-free alternatives for butter and condensed milk, although it may affect the texture slightly.
Can I use different types of chocolate for the icing?
Certainly! While milk chocolate gives a lovely creamy finish, you can experiment with dark chocolate for a richer taste. Just keep in mind that dark chocolate is usually less sweet, which can change the overall flavor profile of your Coffee Slice.
