Ingredients You’ll Need
To whip up this masterpiece, gather these ingredients:
For the sponge:
- 50g walnut pieces
- 225g caster sugar
- 225g unsalted butter, softened, plus extra for greasing
- 200g plain flour
- 4 teaspoons instant espresso powder
- 2 teaspoons baking powder
- 1 teaspoon bicarbonate of soda
- 4 large eggs
- 1-2 tablespoons milk to adjust consistency
For the frosting:
- 350g icing sugar
- 175g unsalted butter, softened
- 2 teaspoons instant espresso powder dissolved in 1 tablespoon hot water
- About 10 walnut halves for decoration
Substitution Options
If you’re missing an ingredient or want to mix things up, here are some swaps:
- Use almond flour instead of plain flour for a gluten-free option.
- Swap out walnuts for pecans if you prefer their flavor.
- Replace caster sugar with brown sugar for a deeper, caramel-like taste.
- For a dairy-free version, use plant-based butter and milk.
Step-by-Step Preparation
Step 1: Preheat and Prep
Start by preheating your oven to 180°C (160°C fan)/Gas Mark 4 or 350°F. Grease two 20cm round cake pans and line the bottoms with parchment paper. This step ensures your cakes won’t stick and will slide out effortlessly. Pro tip: Use a little butter wrapper to grease the pans—it’s efficient and eco-friendly!
Step 2: Blend and Mix the Batter
In a food processor, grind the walnuts and caster sugar until fine. Add the softened butter, flour, espresso powder, baking powder, bicarbonate of soda, eggs, and a splash of milk. Blend until smooth and pourable. The batter should be thick but not stiff. Imagine the color—a lovely pale brown, thanks to the coffee and walnuts.
Step 3: Bake to Perfection
Pour the batter evenly into the prepared pans. Pop them into the oven for about 25 minutes. You’ll know they’re ready when the tops spring back lightly when touched. Let the cakes cool in the pans for 10 minutes before transferring them to a wire rack. Cooling prevents soggy layers later on.
Step 4: Whip Up the Frosting
Sift the icing sugar to avoid lumps, then beat the softened butter until creamy. Add the dissolved espresso mixture and continue beating until the frosting is light and fluffy. Picture spreading this velvety goodness—it’s almost too beautiful to eat!
Step 5: Assemble and Decorate
Place one cake upside down on a serving plate and spread half the frosting over it. Top with the second cake, right-side up, and cover it with the remaining frosting. Arrange walnut halves around the edges for a polished look. Voilà! Your Walnut Coffee Delight is ready to impress.
Chef’s Tip
For an extra touch of elegance, drizzle a bit of melted dark chocolate over the top. It adds a hint of bitterness that complements the sweetness perfectly.

Extra Info

Necessary Equipment
You don’t need fancy gadgets for this recipe. Just grab:
- A food processor or blender
- Two 20cm round cake pans
- An electric mixer or whisk
- A spatula for spreading frosting
Storage Tips
Store your Walnut Coffee Delight in an airtight container at room temperature for up to 2 days. If you live in a warm climate, refrigerate it to keep the frosting from melting. For longer storage, freeze the unfrosted layers wrapped tightly in plastic wrap. When ready to serve, thaw overnight and frost as usual.
To refresh the cake, let it sit at room temperature for 30 minutes before serving. This brings back the moisture and flavor. Avoid microwaving slices, as it can ruin the texture.
Leftover frosting? Keep it in a small container in the fridge for up to a week. Simply bring it to room temperature and re-whip before using.
Tips and Advice
Don’t rush the cooling process—it’s key to preventing soggy layers. Also, sift your icing sugar for lump-free frosting. Lastly, taste as you go! Adjust the coffee strength to suit your preference.
Presentation Ideas
Dust the top with cocoa powder for a chic finish. Or, sprinkle crushed walnuts for added texture. Serve slices on vintage plates for a nostalgic touch. Pair with a latte or cappuccino for a café-style experience.
Healthier Alternatives
Want to lighten things up? Try these variations:
- Gluten-Free: Swap plain flour for almond or oat flour.
- Low-Sugar: Use a sugar substitute like stevia or erythritol.
- Vegan: Replace eggs with flaxseed gel and use plant-based butter.
- Protein-Packed: Add a scoop of protein powder to the batter.
- Spiced: Mix cinnamon or nutmeg into the batter for warmth.
- Fruit Twist: Fold in chopped dried figs or dates for natural sweetness.
Common Mistakes to Avoid
Mistake 1: Skipping the Espresso Powder
Some folks skip the espresso powder thinking it’s optional, but trust me, it makes all the difference. Without it, the coffee flavor falls flat. Always include it for that rich, bold taste.
Mistake 2: Overmixing the Batter
Overmixing leads to dense cakes. Mix just until the ingredients come together. Think of it like folding laundry—not too rough, not too gentle.
Mistake 3: Frosting Warm Cakes
Frosting warm cakes causes the frosting to melt and slide off. Patience pays off here. Cool the cakes completely before assembling.
FAQs
Can I use regular coffee instead of espresso powder?
Absolutely! Dissolve 2 tablespoons of strong brewed coffee in 1 tablespoon of hot water and use it in place of the espresso powder. The flavor might be slightly milder, but still delicious.
How do I store leftover frosting?
Keep leftover frosting in an airtight container in the fridge for up to a week. Before using, let it come to room temperature and give it a quick whip to restore its fluffiness.
Can I make this cake ahead of time?
Yes! Bake the layers a day in advance and store them in an airtight container. Frost the cake just before serving to ensure freshness.
What if I don’t have a food processor?
No problem! Finely chop the walnuts and mix everything by hand. It takes a bit more effort, but the results are worth it.
Is this cake kid-friendly?
While kids generally love sweets, the coffee flavor might be strong for some. Reduce the espresso powder to 2 teaspoons for a milder taste.
Can I freeze the frosted cake?
It’s better to freeze the unfrosted layers. Frosting doesn’t freeze well and can become grainy upon thawing.
How do I prevent the cake from sticking to the pan?
Grease the pans thoroughly and line them with parchment paper. This double layer ensures the cakes release easily.
What other nuts can I use?
Pecans or hazelnuts work wonderfully. Toast them lightly for enhanced flavor.
Can I reduce the sugar?
Yes, but keep in mind that sugar affects the texture. Reduce by no more than 25% to maintain structure.
How do I check if the cake is done?
Insert a toothpick into the center. If it comes out clean or with a few crumbs, it’s ready. Don’t overbake, or the cake will dry out.
