As this Gluten-Free Vegan Lemon Drizzle Cake has been so popular, I decided it was time to make another simple citrus cake, this time using oranges. Inspired by my Gluten-Free Vegan Vanilla Cake, this is a simple orange-infused sponge with a simple orange-infused buttercream.
Where does the orange flavour in this Orange Cake come from?
- I used my go-to sponge cake recipe, but added orange zest and substituted some of the milk with orange juice. This adds natural sweetness and also enhances the orange aroma, and simultaneously tangy and nectar-like flavour.
- You can either use freshly squeezed orange juice, or orange juice from a carton. If you prefer a stronger orange flavour, you can add some more orange extract – instructions in recipe notes.
- For the frosting, I used my favourite cashew-based buttercream recipe, but used orange juice instead of water or milk.
- If you prefer a stronger orange flavour you can add a couple of drops of orange extract to the buttercream – see recipe notes for instructions.
- Finally, I decided to top the cake with some clementine segments, which not only serve an aesthetic purpose, but also add extra juicy sweetness.

- Mix together all the ingredients in a glass mixing bowl.

Tip: Line the tins with greased baking paper to make the sponges easier to remove afterwards.

How to make the Orange Buttercream Frosting

Tip: Make sure the cashew nuts are soaked to make them easier to blend. Soak them overnight in cold water or in boiling water for at least 15 minutes.

Tip: You will have to mix it around a few times to make it easier to blend up.
- Apply the frosting to the cake using a palette knife for frosting.

To frost and decorate the cake:
