Light & Moist Coffee and Walnut Cupcakes with Coffee Buttercream Frosting!


I have been trying to think of Cupcake recipes that people would want to see and make themselves, and these came up. My Coffee Cake recipe was so popular and such a big hit with my readers that I know these will be loved by all too! My Carrot & Walnut Cupcakes are such an old recipe on this blog now that they’re rarely seen, but these will hopefully bring the Walnut love back.

When I was little I never really liked Nuts and I can’t drink Coffee… so these sound like my childhood nightmare. HOWEVER. These Cupcakes are SO damn moist and delicious I just can’t get over it – and the nuts give that added extra crunch that everybody craves in a cupcake! Sometimes I can find that cupcakes can be a bit sickly, or too sweet? But the Coffee in the sponge and buttercream gives it a delightful twist of almost bitterness with sweetness? It’s delicious either way.


If you like Coffee Cake then you will utterly adore these. One of my main Family Friends literally CONSTANTLY says that she likes Walnuts with her Coffee Cake, so these were made as her little Birthday treat and they went down an absolute storm! Even I, the childhood nut/coffee hater was converted to these  and even my own Mum was surprised by that. Like, she was shocked and didn’t believe me that I liked it! How dare she. Cupcakes will always convert me to liking something! They are cupcakes after all…

But anyway, I use just a regular Instant Coffee in the actual Cupcakes and in the Frosting, these really are SO simple to achieve yourself. Of course, if you don’t actually like walnuts you can use a different nut that you prefer, or you don’t even have to use nuts. I have made this recipe countless times now with or without nuts and the cupcakes themselves are just so light and delicious that any Coffee lover will love these. Enjoy!

Tips and Ideas

I buy my Cupcakes Cases from Iced Jems – here!

I used the regular strong Instant Coffee that my parents have in the cupboard – its the same coffee I used for my Coffee Cake so I know it works!

Be really careful not to over bake the cakes or you might lose the light texture – I bake mine for 18 minutes in my oven, every single time, as I know how long my oven takes to bake certain things – all ovens can be different!

These cupcake will last in an airtight container for 3 days!

  3. Hi, what could I replace the eggs with in this recipe that won’t make too much of a difference to the flavour and texture?

  4. Hi Jane!
    Could I use this recipe for one larger cake? I know you have a recipe for a coffee cake but I just wanted to check if I could use this one as I want to make a coffee and walnut cake. Thank you! Paula

  5. Hi
    I made these cupcakes a while ago (and they were delicious!) but next week I’d like to take them into the school that I work at for the staff but we cannot have nuts on the premises. Would I just use the same recipe without the walnut or would I need to alter the amount of other ingredients?
    Thankyou 🙂

  6. Hi Jane, I only discovered your website last week and I am completely spoilt for choice! I’m practicing piping could you tell me what frosting tip you used to pipe the coffee buttercream? Thanks

  7. Hello Jane,

    these cupcakes look delicious! Thank you for sharing the recipy.
    I want to make the cupackes for Christmas, but was wondering if it is possible to put them in the freezer and make the buttercream on the day you want to serve the cupcakes?

  8. Hi. Thank you for the recipe. It seems delicious and I’d like to try it. So, if we don’t have self rising flour, how much baking powder or baking soda that we need? Thank you.

  9. Me and my sister are addicted to coffee so I KNOW she would just love these cupcakes. Your recipes never disappoint Jane. Thank you for sharing 🙂
