Coffee Slice Ingredients
• Here’s what you’ll need for a delicious Coffee Slice!
For the Base
- Arnott’s Marie biscuits – These are the perfect foundation; feel free to swap them with any sweet, plain biscuit if necessary.
- Instant coffee granules – Imparts a robust coffee flavor; espresso powder can be substituted for a deeper taste.
- Cocoa powder – Adds a luxurious chocolate richness; unsweetened cocoa powder is recommended.
- Light brown sugar – Provides sweetness with a hint of caramel; can be substituted with granulated sugar if needed.
- Sweetened condensed milk – Binds the ingredients together while adding creaminess; it’s best not to replace this with evaporated milk.
- Desiccated coconut – Offers delightful texture; omit it if coconut isn’t your thing and add more crushed biscuits instead.
- Salted butter (melted) – Contributes richness; unsalted butter can be used, just adjust the salt amount accordingly.
- Vanilla – Elevates the overall flavors, and pure vanilla extract is the way to go; imitation vanilla will also work if necessary.
- Boiling water – Essential for dissolving the coffee granules; no substitute is needed here.
For the Icing
- Milk chocolate – Creates a sweet and glossy layer on top; dark chocolate can be a delightful change for a richer flavor.
- Salted butter (for icing) – Increases the glossiness and richness of your icing; same substitution options as above apply.
- Instant coffee granules (for icing) – Deepens the flavor profile; stick with the same kind used in the base for consistency.
With these simple ingredients, your Coffee Slice is just a few easy steps away! Enjoy the luscious blend of flavors that this no-bake delight has to offer.
Step‑by‑Step Instructions for Coffee Slice
Step 1: Prepare the Tin
Start by greasing a 20×20 cm baking tin with a little butter to prevent sticking. Then, line the base and sides with baking paper, allowing some overhang. This will make it easier to lift out your Coffee Slice once it’s set. Set the prepared tin aside as you get ready to make the base.
Step 2: Crush the Biscuits
Using a food processor, pulse the Arnott’s Marie biscuits into fine crumbs, achieving a sand-like texture. If you don’t have a food processor, simply place the biscuits in a sealed bag and crush them with a rolling pin until finely crushed. Pour the biscuit crumbs into a large mixing bowl and set aside for the next step.
Step 3: Dissolve the Coffee Mixture
In a small bowl, combine the instant coffee granules, cocoa powder, and light brown sugar. Carefully pour in 100ml of boiling water and stir until the mixture is completely dissolved and smooth. The aroma will be wonderful! This coffee mixture will enhance the flavors of your Coffee Slice, so set it aside to slightly cool.
Step 4: Mix the Base Ingredients
In the large bowl with the biscuit crumbs, add the sweetened condensed milk, desiccated coconut (if using), melted salted butter, vanilla extract, and the cooled coffee mixture. Stir everything together until well combined and you achieve a thick, sticky mixture. This will form the rich base for your Coffee Slice.
Step 5: Press the Mixture into the Tin
Transfer the filling into the prepared tin and use the back of a spatula or your fingers to firmly press the mixture down into an even layer. Ensure it is compacted well to hold its shape when sliced. The top should be smooth and flat, ready for the delicious chocolate icing that will come next.
Step 6: Prepare the Chocolate Icing
For the icing, break the milk chocolate into small pieces and place it in a microwave-safe bowl along with the melted salted butter. Heat in the microwave in 20-second intervals, stirring in between, until the mixture is smooth and glossy. Add in the instant coffee granules and mix well, then let it cool slightly before spreading.
Step 7: Ice the Coffee Slice
Pour the warm chocolate icing over the pressed coffee base. Using a spatula, carefully spread it into an even layer that covers the entire surface. It should be shiny and inviting. Place the tin in the refrigerator to chill and allow the icing to set for at least 2 hours before slicing into squares.
Step 8: Slice and Serve
Once set, use the overhanging baking paper to gently lift the Coffee Slice out of the tin. Place it on a cutting board and slice it into squares with a sharp knife. For the best results, wipe the knife with a warm cloth between cuts. Enjoy your delicious homemade Coffee Slice with a cup of your favorite coffee!

Coffee Slice Recipe FAQs
What type of biscuits should I use for the Coffee Slice?

What should I do if my Coffee Slice is too gooey?
If your Coffee Slice ends up a bit gooey, it might be due to ingredient measurements. Make sure to accurately measure all ingredients, especially the condensed milk. Additionally, if you find it’s still too soft after chilling, you could try adding a bit more biscuit crumbles to absorb the moisture, pressing it back into the tin to set firmly.
Are there any allergens I should be aware of in this recipe?
Certainly! This Coffee Slice contains common allergens including gluten (from biscuits), dairy (butter and sweetened condensed milk), and may also contain nuts if you decide to add them as variations. If you’re serving guests, be sure to ask about any allergies!
Can I substitute any of the ingredients for dietary needs?
The more the merrier! You can use unsalted butter instead of salted and opt for dark chocolate for a richer icing. For a dairy-free version, try coconut cream in place of sweetened condensed milk and dairy-free chocolate for the icing. Just be sure that the biscuits are also dairy-free if needed!
