Super easy Vegan Coffee Walnut Cake Recipe – perfect if you have some walnuts in the cupboard! Made with flax seeds, vanilla, and instant coffee.
This Vegan Coffee Walnut Cake Recipe turned out so much better than I could have dreamed – and funnily, it came about in a pretty spontaneous kind of way. What to do when you have too many walnuts in the house? Right, a walnut cake. And what goes with walnuts better than anything else? Coffee!
That was pretty much my thought process when I found a massive bag of walnuts at the back of my cupboard, which were going off soon. A good excuse to make a cake! (not that I would need an excuse for this ;))
What a perfect snack this Vegan Coffee Walnut Cake was – especially with the sweet chai-style topping!
Hope you will enjoy this quick and easy recipe – let me know how it turned out in the comments, if you make this 😉

How to make this Vegan Coffee Walnut Cake Recipe
How to make your vegan cake cake
To start with, mix your flaxseeds with your 3 Tbsp of hot water and set them aside for 10 minutes. While you’re waiting, mix together the flour, baking powder and cinnamon and add a handful of walnuts.
Extra Tip: Be sure to leave some whole walnuts to decorate your cake with at the end.
Now blend together with your coffee and soy milk along with your maple syrup and add the rapeseed oil.
Next, you’ll need to go and get your flaxseeds out of the fridge and add them to the flour mix. Then slowly add the liquids to this mixture whilst stirring with a spatula.
Once you’ve done that, use the coconut oil to grease the inside of a cake tin (I used a round one) and add your cake mix to the tin.
Extra Tip: Personally, I don’t like using baking paper for cakes because it can easily get stuck to the cake and ruin it. So instead I grease up the tin and lightly dust it with some flour.
For the final step of making the cake, bake it in an oven for 30 minutes at 180ºC. Once you’ve taken the cake out of the oven, be sure to let it cool down completely before adding the icing…
How to make your vegan icing
Put all your icing sugar in a bowl and slowly add your chai tea and vanilla essence whilst stirring the mixture with a fork. Add a smidge of soy milk until the mixture is smooth – but be careful not to make it too thick.
Extra Tip: If it it starts looking a little runny simply add more icing sugar to balance it out. But not too much, this icing should be thick but not too thick and definitely not crumbly.
Once your cake has cooled down from being in the oven, gently pour the icing onto the cold cake, add your leftover walnuts to the top for decoration and put it in the fridge to set.

For the icing:
- Add 2 cups of icing sugar to a bowl, then slowly add the chai tea and vanilla essence whilst stirring with a fork.
