Ingredients You’ll Need
Gathering the right ingredients for this slice is both straightforward and essential, as each component plays a vital role in balancing flavors and textures. From the crunchy base to the luscious chocolate topping, everything combines perfectly for that irresistible bite.
- 1 ½ cups crushed digestive biscuits or graham crackers: These form the crunchy, slightly sweet base that holds the slice together and gives it texture.
- 1 cup finely chopped walnuts: Adds a nutty crunch that complements the espresso’s boldness beautifully.
- 1 cup sweetened condensed milk: Acts as the glue binding the dry ingredients and adds creamy sweetness.
- 2 tablespoons instant espresso powder: Infuses the slice with rich, robust coffee flavor without bitterness.
- 2 tablespoons cocoa powder: Enhances the chocolate notes and adds depth to the overall taste.
- 1 teaspoon vanilla extract: Provides a warm, floral undertone that rounds out the flavors.
- ¼ teaspoon salt: Balances the sweetness and intensifies all the other flavors.
- ½ cup dark chocolate chips (melted, for topping): Creates a smooth, decadent layer that contrasts the crumbly base.
- 2 tablespoons chopped walnuts (for garnish): Adds an attractive finish along with an extra bit of crunch on top.
How to Make No-Bake Espresso Walnut Slice Recipe
Step 1: Prepare Your Pan
Start by lining an 8×8-inch baking pan with parchment paper, making sure to leave some overhang. This makes it really easy to lift the entire slice out once it’s set, ensuring clean cuts and minimal mess.
Step 2: Mix the Dry Ingredients
In a large bowl, combine the crushed biscuits, finely chopped walnuts, cocoa powder, espresso powder, and salt. Stir these together until they are evenly blended. This step ensures that each bite is perfectly balanced with texture and flavor.
Step 3: Add the Wet Ingredients
Pour in the sweetened condensed milk and vanilla extract to the dry mix. Stir everything together until you get a sticky, cohesive mixture that can easily be pressed into the pan. This part is crucial for achieving that fudgy texture without baking.
Step 4: Press and Top
Firmly press the mixture evenly into the prepared pan. Then, pour the melted dark chocolate over the top and gently spread it using a spatula to create a smooth layer. Finally, sprinkle the chopped walnuts over the chocolate to add a beautiful contrast and extra crunch.
Step 5: Chill and Slice
Place your pan in the refrigerator and let the slice chill for at least 2 hours or until it’s completely firm. Once set, lift the slice out with the parchment overhang and cut it into approximately 16 squares for perfect portions.
How to Serve No-Bake Espresso Walnut Slice Recipe
Garnishes
Enhance your presentation by adding a light dusting of cocoa powder or a few coffee beans on top. A dollop of whipped cream or a sprinkle of finely grated dark chocolate can also create a luxurious finish that makes the slice feel extra special.
Side Dishes
This espresso walnut slice pairs wonderfully with a cup of rich, freshly brewed coffee or a creamy latte, amplifying the espresso flavor. For a refreshing contrast, a small bowl of fresh berries adds a juicy burst that balances the sweetness perfectly.
Creative Ways to Present
Try serving these slices on a wooden board lined with parchment for a rustic vibe or on elegant dessert plates garnished with edible flowers to impress guests. Wrapping individual slices in parchment paper tied with twine also makes for charming gift presentations that show you care.
Make Ahead and Storage
Storing Leftovers
Leftover No-Bake Espresso Walnut Slice Recipe treats can be stored in an airtight container in the refrigerator for up to one week. This keeps the texture firm and flavors fresh, so you can enjoy one any time you need a sweet espresso fix.
Freezing
You can freeze these slices for up to one month if you want to prepare them ahead of time or save some for later indulgence. Wrap them tightly in plastic wrap and place in a freezer-safe container to prevent freezer burn and preserve their delicious taste.
Reheating
Since the slice is best enjoyed chilled, there’s no need to reheat. Just allow frozen slices to thaw in the refrigerator for a few hours before serving. This keeps the texture intact and the flavors vibrant just like when freshly made.
FAQs
Can I substitute the espresso powder with instant coffee?
Yes, you can use instant coffee granules if you don’t have espresso powder on hand. Keep in mind espresso powder is more concentrated, so use slightly less instant coffee or expect a milder coffee flavor.
Is it possible to make this dessert nut-free?
Absolutely! You can omit the walnuts or substitute them with seeds like pumpkin or sunflower seeds to maintain some crunchiness. Just be mindful that the overall flavor and texture will change slightly.
How long does it take to set in the fridge?
The slice needs about 2 hours in the refrigerator to properly firm up. For best results, avoid rushing this step as it ensures clean slicing and a perfect texture.
Can I use milk chocolate instead of dark chocolate for the topping?
You can use milk chocolate if you prefer a sweeter topping, but dark chocolate offers a nice balance against the slice’s rich espresso and walnut flavors. Choose based on your taste preference.
Is this recipe vegan-friendly?
This recipe is not vegan as it contains sweetened condensed milk and dark chocolate chips that typically include dairy. However, you could experiment using vegan condensed milk and dairy-free chocolate to create a vegan version.

I truly adore the No-Bake Espresso Walnut Slice Recipe because it combines so many wonderful textures and flavors into one easy, fuss-free dessert.
