Coffee & Walnut Cake


Coffee & Walnut Cake

Now I've perfected my sponge cakes I thought I'd make one of my favorites – coffee and walnut. The sponge is moist and light with a thick coffee frosting.

Servings 8 large slices


  • 2x 7"/8" cake tins



  • 600 ml soya milk Only soya works with this recipe
  • 1 tbsp apple cider vinegar or use lemon juice
  • 2 tbsp chia seeds milled
  • generous pinch of sea/pink salt
  • 1 tsp vanilla extract
  • 1 tsp baking soda
  • 2 tsp baking powder
  • 350 g plain flour I used wholemeal. If using self raising flour leave out the 2 tsp baking powder.
  • 200 ml veg oil I used rapeseed
  • 130 g sugar I used coconut sugar – nice caramel flavour
  • 5 tsp instant coffee


  • 100 g vegan butter/spread
  • 400 g icing sugar
  • 3 tsp instant coffee Mixed with 4 tbsp water/milk
  • 1 tsp vanilla extract
  • walnuts



  • Preheat the oven to 180oC/356oF
    Mix the milk and vinegar/juice and set aside for 15 minutes (the acid in the vinegar/juice reacts to the proteins in the milk and sours it) Makes butter milk.
    Meanwhile mix the flour, salt, chia seeds, baking soda & powder in a large bowl.
    Add the instant coffee to the milk mix and stir until dissolved.
    Pour into the bowl with the flour and add the oil and vanilla. Mix until everything is combined.
    Add the sugar and fold into the cake batter.
    Pour equally into 2 lined cake tins (7") and bake for 25 minutes.
    Once the 25 minutes is up leave to cool on a wire rack for half an hour or more.
    Gently remove from the tins and remove any parchment paper. Leave to cool fully for a couple of hours.


  • Add all the ingredients to a large bowl and carefully whisk until you have a thick frosting. If you find the mix too thick add a little more water, 1 tbsp.
    Decorate the cake with the frosting and walnuts. Enjoy!



Tip: I used wholemeal flour but you could use white or gluten free. I love walnuts but I know a lot of people who don’t. If you love them why not add a few crushed walnuts into the cake mix.
As you can see from the video whisking the icing sugar was a bit messy. Make sure you use a large bowl to contain the mess.
