A homely Coffee and Walnut Cake with a luscious coffee frosting that is delicious and easy to make. Recipe with step-by-step photos.
Coffee Cake
In some countries, there exists what is called a coffee cake which actually does not contain any coffee but it is called such because it is intended to be eaten with a cup of coffee.
This Coffee and Walnut Cake is actually a coffee cake, in that it is heady with coffee flavour in both the sponge and frosting, thanks to a touch of instant espresso powder or instant coffee powder.
Coffee and Walnut Cake
Coffee and Walnut Cake is a familiar sight from my childhood, it being a regular feature in my parents’ bakery. Despite its familiarity and, hence, nostalgic memory, I must confess that coffee-flavoured cakes were not my favourite as a child.
In fact, I’m not sure I even liked drinking coffee until well into my late twenties. Up until then, it was more a case of having coffee with my milk than it being the other way around.
These days, I will happily knock back a strong espresso after a meal without even a flinch.
Coffee and Walnut Cake Recipe
This wonderful recipe for Coffee and Walnut Layer Cake comes from Kitchen by Nigella Lawson.
For me, what is unusual about this recipe is that the walnut component is not simply for decoration; a good quantity of walnuts is ground into a fine powder for use in the sponge, thereby lending the cake a tender and moist texture.
Unlike most coffee cake recipes, I suppose, this Coffee and Walnut Cake recipe uses instant espresso powder instead of the more subtle and plain instant coffee.
Fearing that the coffee flavour would be too strong, and bearing in mind that my children eat everything that I bake, I used instant coffee powder instead for just that hint of coffee taste. Both of my children loved this cake, perhaps a by-product of drinking the foam from my cappuccinos …
This is a really lovely Coffee and Walnut Cake, both to look at and to eat. Next time around, I think I will up the coffee flavour and use instant espresso powder as per the original recipe. You may as well go all the way!
So if you prefer a stronger coffee-flavoured cake, I would suggest using instant espresso powder. But for a cake with a mild coffee flavour, I think any mainstream instant coffee powder should be fine.
And just in case you were wondering, yes, we keep instant coffee powder in our home! My husband has a soft spot for it, and when he can’t be bothered to pop a coffee pod into our coffee machine (yes, there are those days!), he will go the instant coffee route. The rest of the time, I use instant coffee in baking, like in this Ultimate Chocolate Cake.
How to Make Coffee and Walnut Cake
What I love about this Coffee and Walnut Cake recipe is that everything is done in the food processor.
You start by blitzing the walnuts and sugar into a fine powder, before adding the rest of the ingredients. So simple!

RateIngredients
For the cake
- 2–4 teaspoons instant coffee or instant espresso powder
- 1 tablespoon boiling water
- 50 g (2 oz) walnuts
- 225 g (1 cup) caster sugar (super-fine sugar)
- 225 g (2 sticks) unsalted butter, softened
- 200 g (1 1/3 cup) plain flour (all-purpose flour)
- 2 1/2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 4 eggs
- 1–2 tablespoons milk
For the frosting
- 2 1/2 teaspoons instant espresso powder
- 1 tablespoon boiling water
- 350 g (2 1/2 cups) icing sugar (powdered sugar)
- 175 g (1 1/2 sticks) unsalted butter, softened
- walnut halves for decorating
Instructions
For the cake
- Preheat the oven to 180°C/350°F (without fan).
- Grease and line the base of two 20 cm (8 inch) cake tins.
- Dissolve the instant coffee powder in the boiling water. If you want a strongly coffee-flavoured cake, I suggest using 4 teaspoons.
- Place the walnuts and caster sugar into the bowl of a food processor and blitz until you have a fine powder.
- Add the butter, flour, coffee mixture, baking powder, baking soda, and eggs.
- Blitz again until you have a smooth batter.
- With the motor still running, pour a little bit of milk down the funnel until the batter is a soft, spreadable consistency.
- Divide the batter between both cake tins.
- Bake for about 25 minutes, or until the cakes are lightly golden and a cake skewer inserted in the centre comes out clean.
- Cool the cakes in their tin on a wire rack for about 10 minutes before inverting onto a wire rack. Remove the cake tins and baking paper from the cake.
- Leave the cakes to cool completely.
For the frosting
- Dissolve the instant espresso powder in the boiling water
- Using a stand mixer with the flat paddle attachment, beat together the icing sugar (powdered sugar), butter and coffee mixture until you have a thick and spreadable frosting.
To assemble the cake
- Place one sponge upside down on a plate or cake platter.
- Spread half of the frosting onto the sponge and spread it evenly.
- Place the second sponge on top.
- Cover the top sponge with the remaining frosting.
- Decorate the cake with walnut halves.

Update
This recipe was first published on 21 June 2013. It has been updated with new photos and more comprehensive recipe notes.
This cake looks so scrummy yummy! Congrats on your baby! I also had a baby a few months ago and my blog has literally gone to seed. And like you I have tonnes of material and pictures but I just can’t seem to eek out time to assemble a post. I am captivated by this cake though!
Congratulations also to you!! I guess it is an understatement to say that life gets busier with a baby, but I suppose our priorities also change. Processing photos and writing blog posts requires more time than most people think but it’s still a nice hobby to have 🙂 I hope you and your baby are doing well.
Beautiful pictures and the cake looks delicious!!! I discovered your blog recently and love it! I couldn’t help but notice your espresso caffettiera in the background, just like the one Nigella Lawson has as seen on her new show Nigellissima. I have been looking for one just like it for ages. Can you please tell me where I can purchase one? Is it available online?
Thank you very much!
Rosa
Hi Rosa,
I bought my caffettiera in a specialty kitchenware store in Zurich many years ago which, sadly, no longer exists. I recognised it from one of Nigella’s earlier shows and always kept an eye out for it. It seems to not be widely available (unlike the Bialetti brand), but I would recommend checking out Italian delis and specialty stores. It is called la “Signora” caffettiera and it is made in Italy. I hope you will have some luck finding one!
Coffee and walnut is such a classic tea room cake. I love the crunch of nuts and that thick swirl of icing – yours looks just wonderful.
Thank you! It is indeed a classic tea cake and I can’t wait to make it again soon.
Congratulations on the birth of your baby! Life will be enriched for evermore.. Walnut cake looks delicious.
Thank you, Sue! You words are very true 🙂
Congratulations. I love coffee and walnut cake, your looks lovely.
Thanks, Laura! Good to hear of another coffee and walnut cake fan 🙂
it is wonderful that your social life is thriving because of the baby. Well, in my experience,it was quite the opposite for me. I taught myself to bake after the birth of my baby. I took the time out to learn the science and the art of it by trying little baking experiments during her nap time.
Beautiful walnut coffee cake and the pictures ever so gorgeous.
Hi Anita,
That’s really lovely that you started baking after the birth of your child. In the early weeks, whenever my baby took a nap, so did I! Only after a few weeks did I muster up the energy to get back into the kitchen, and I’m thankful that I did. I know that having a baby for some can be a bit isolating but, at the end of the day, mother and baby just needs to be happy and healthy, whether it means having a constant stream of visitors or just quiet time for your immediate family.
So wonderful to see you posting again Thanh. This gorgeous cake does indeed look fancy. I bet it tastes divine too! Nigella’s recipes are always so deliciously reliable!
Lovely to see you here, Jennifer 🙂 You are right – Nigella’s recipes are always reliable and it’s probably why I always turn to her books when I don’t have time to experiment. I also haven’t cooked from Kitchen too much so I was happy to give this particular recipe a go.
This cake looks so sophisticated and delicious!!! I can’t wait to have some friends over for afternoon tea just so i can make this cake 🙂
Congratulations on your baby, what a precious gift!
thanks for inspiring me
Thank you! Our little baby is just the most wonderful thing that has happened to us 🙂 Hopefully you will have a chance to make this cake soon.
Thanh the first coffee cake which I made using walnuts was Delia’s recipe and I haven’t looked back since. I bought a copy of Kitchen some time back but haven’t got around to giving it a good workout 🙂 Delia drizzles a sugar syrup over it which I think gives the cake that extra edge. I think I need to try Nigella’s to compare, well I’d come up with any excuse to bake plus I need to bake something for a potluck on Thursday.
PS: I’m so happy to hear that your little one is thriving. Enjoy every precious minute with him.

Delia’s recipe sounds really lovely. Which book is it from? I haven’t cooked too much from Kitchen either but, slowly, I’ve come to realise that it has some pretty nice recipes. Hope you are doing well too 🙂
I found Delia’s recipe on her site. Do give it a try when you get a bit of time, I promise you, you’ll not regret it 🙂

I liked Nigella’s version, it’s a decadent cake with a subtle nutty note. The buttercream brings the cake together. Well now I have another coffee cake in my repertoire thanks to ya 🙂
Yum, Coffee and Walnut is an definite favourite of mine, yet to find my perfect recipe though.. This looks delicious, will definitely try it. Pleased to find your blog, it looks lovely, excited to explore more.
Thanks for popping by! Off to have a nosey at your blog … 🙂
This looks amazing! Definitely trying out this recipe this weekend. Also, LOVE your photography!
Thanks, Josie! I hope you will enjoy this cake.
Coffee and walnut cake is one of my favorites. I love that the walnuts are ground with the sugar and actually in the cake itself; may just have to try this recipe! Would it also be possible to use instant coffee for the icing instead of espresso powder? (I live in Sydney, and instant espresso powder has eluded me no matter where I’ve looked.)
Yes, of course, you could use instant coffee for the icing. I would suggest diluting a few teaspoons in a bit of boiling water and then adding this mixture to taste to the icing sugar. The instant espresso powder available where I live is a Nescafe brand which is sold next to their usual instant coffee. I’m surprised that it is not available in Sydney, although I must admit that I haven’t used it to make espresso to drink – I’ve bought it solely for Nigella’s baking recipes! I hope you will enjoy this recipe.
It looks so good! I must admit that coffee cake has never been one of my favourites, but the older I get, the more I think I’d enjoy it – a lot!
That’s very true, Anna! I wasn’t a fan of coffee-flavoured anything as a child, but now I find I quite like the bitterness. And I particularly surprise myself now when I take coffee without milk!
This looks amazing!! I was going to bake this eve but have spent my time looking through your recent posts. Yummy xx
I found this on recipe on Pinterest and just had to give it a go.
It is by far the best cake I’ve ever made.
Truly scrumptious 🙂
My husband has already asked for me to make it again.
Definitely one for the girlies on a coffee morning.
Thank you 🙂 x
I’m so happy to hear that this recipe was a huge success for you! My husband was also a big fan of this cake but, conversely, has asked me to refrain from making it too often … because he ends up eating too much of it 😉
My hubby makes this coffee cake for me every year. He’s not a cook but does this beautifully due to a lovely recipe explained perfectly. Such a wonderful treat. Thank you for sharing, our family thanks you with big, big, big hugs x
Hi Sue,
Oh that’s so wonderful to hear!! You have such a lovely husband 🙂 I’m glad you and your family enjoy this recipe – it’s one that I also love and ought to make more often. In fact, I might ask my husband to make it for me 😉 Thanks for popping by and I hope you will find more recipes here to enjoy xx
What an excellent recipe! I always love Nigella’s recipe and this cake is no exception. My daughter has even asked me to make this as her birthday cake!

This looks amazing! I cannot wait to give it a try!

This is such a classic cake and when it’s done like this and simply served up you can’t beat it!
Thank you! I love making classic and good, old-fashioned cakes. They win every time!
I’ve just found your blog through Facebook and I’m in love. Beautiful photos and pictures. And I love the combination of this cake.
Hi Amy,
Thank you for your lovely words!
Hi Thanh, I’m going to make this cake for my daughters 14 th birthday (she’s loves coffee flavoured treats) but my food processor unfortunately broke a while back, could I use an electric whisk to make this?
Thank-you
British and Canadian/USA baking powder have different chemical compositions. Please confirm which is the closest to Australian? (Before my father died some years ago, he spent some time investigating this for us, because my old British family recipes were not working out well in Canada with local ingredients). Also butter has different fat content. Eggs, too are different sizes. Even the flour differed, but that wasn’t a huge problem. This might sound like a joke…as though Australian chickens might be very different, but with baking these things can have a big impact! Maybe there is a new version of “Why did the chicken cross the road..?.”
Hi Sue,
I have also found that the composition of baking powder varies from country to country. I tend to use British baking powder in my recipes, but also the local French, German and Swiss brands as a back-up, although when using any of the latter, I find that my cakes do not rise as much. But some would argue that the difference is negligible.
Ingredients can indeed vary from country to country, but they can also vary from brand to brand within the same country.
Wherever you live, I think you should just make the best of the ingredients available to you 🙂 And once you are familiar with how certain ingredients work in your recipes, you can make adjustments to your taste.

Thank you!
Easy to make and came out great!

Hi Carole,
That’s great to hear! Thanks for popping by to leave your comment 🙂
Hi, I’m not a fan of walnuts but was wondering if making this without the nuts would change the moistness of the cake?
Hi Dana,
The nuts here do help to keep the cake soft and moist. But you can substitute with other nuts like almonds or hazelnuts, if you prefer. The taste should be similar 🙂
