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!

Instructions

For the cake

  1. Preheat the oven to 180°C/350°F (without fan).
  2. Grease and line the base of two 20 cm (8 inch) cake tins.
  3. Dissolve the instant coffee powder in the boiling water. If you want a strongly coffee-flavoured cake, I suggest using 4 teaspoons.
  4. Place the walnuts and caster sugar into the bowl of a food processor and blitz until you have a fine powder.
  5. Add the butter, flour, coffee mixture, baking powder, baking soda, and eggs.
  6. Blitz again until you have a smooth batter.
  7. With the motor still running, pour a little bit of milk down the funnel until the batter is a soft, spreadable consistency.
  8. Divide the batter between both cake tins.
  9. Bake for about 25 minutes, or until the cakes are lightly golden and a cake skewer inserted in the centre comes out clean.
  10. 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.
  11. Leave the cakes to cool completely.

For the frosting

  1. Dissolve the instant espresso powder in the boiling water
  2. Using a stand mixer with the flat paddle attachment, beat together the icing sugar, butter and coffee mixture until you have a thick and spreadable frosting.

To assemble the cake

  1. Place one sponge upside down on a plate or cake platter.
  2. Spread half of the frosting onto the sponge and spread it evenly.
  3. Place the second sponge on top.
  4. Cover the top sponge with the remaining frosting.
  5. Decorate the cake with walnut halves.

    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!

      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.

    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.

      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.

    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 🙂

    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.)

    Reply
    • eat, little bird 10 July 2013

      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.

  13. 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!

      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 😉
