If you’re looking for an easy (and delicious) way to use up oranges this citrus season, this vegan orange loaf cake is the answer. It comes together in just a few easy steps and uses 10 pantry staple ingredients. You can even swap the oranges out for their slightly more exotic cousins to make a vegan blood orange loaf cake!

Ingredients overview

  • Plain flour: Good old plain flour does the trick for this recipe. You could possibly try swapping this out for gluten-free all-purpose flour, although I haven’t tried this personally.
  • Baking powder: This is the leavening agent and adds volume to the loaf cake, it also helps to create a fluffy texture.
  • Soy milk: Together with apple cider vinegar, these ingredients are mixed together to form a vegan “buttermilk”. This will help the cake to become super fluffy and light. You can use another plant-based milk of your choice if you want to keep this recipe soy-free.
  • Olive oil:  This helps to keep the cake moist once baked, keeping it tender and fluffy. I recommend using light olive oil if you’re not a fan of its flavor. Feel free to also use rapeseed, sunflower or another neutral oil in it’s place.
  • Light muscovado sugar: I love using light muscovado (not to be confused with dark muscovado) in baked goods as it is less refined than most other sugars and gives a subtle caramel flavour. You can use cane sugar, coconut sugar or light brown sugar in its place.
  • Orange juice and zest: The star of the show, the orange flavor really shines through in this recipe. You can use regular or blood oranges depending on what’s available or in season.
  • Vanilla extract: Although you won’t be able to taste much vanilla coming through in the end, it helps to balance the zesty-ness of the cake.
  • Organic powdered sugar/Icing sugar: This forms the base of the standard icing which is flavored with freshly squeezed orange juice. You can use blood oranges to give the glaze a wonderful peachy-pink hue.

How to make this recipe (with step-by-step images)

(Full ingredient quantities and instructions can be found in the recipe card at the end of this post)

Step 1: Prepare

Like with any recipe, preparation is key. I can’t begin to tell you how many times I’ve forgotten or missed a step when making a recipe! So first thing, make sure you have all your equipment out and ingredients weighed out and ready to go.

  • Preheat your oven to 175°C (350°F).
  • Get the equipment ready (1 large bowl, 1 medium bowl, a couple of small bowls, whisk, rubber spatula, loaf tin, parchment paper, citrus press, grater, cooling rack)
  • Line an 8″ loaf tin with parchment paper and set it aside.
  • Weigh out all ingredients, grate orange zest, squeeze orange juice, etc.

 

Step 2: Make the orange cake batter

Next prepare the batter by first making the vegan buttermilk. Add the soya milk and apple cider vinegar to a small bowl, stir and allow to sit for 10 minutes. It will curdle (this is what you want!).

Then add the remaining wet ingredients to the buttermilk mixture (orange juice, orange zest, and vanilla extract). Whisk everything to combine!

Get a large separate bowl for the dry ingredients and whisk together the flour, sugar, baking powder, and salt. Pour the wet ingredients into the bowl with the dry ingredients and whisk until evenly mixed.

Step 3: Bake 

Add the cake batter to the prepared loaf pan and bake for 50-55 mins. Check the cake is ready by inserting a knife or toothpick into it, which should come out clean. Allow the cake to cool in the pan for about 10 minutes before transferring it to a cooling rack.

Step 4: Make the glaze

Now you can relax for most of the time while your loaf cake is in the oven, you only need a couple of minutes to get the glaze ready. Simply whisk together the icing sugar and blood orange juice until smooth and set aside, that’s it!

Once the cake is baked and cooled, you can drizzle the icing on top, using as little or as much as you’d like!

Storage instructions

Store this vegan orange cake in an airtight container at room temperature for up to 5 days.

Expert tips

  • Use unwaxed oranges: Organic if possible. Waxed fruits are generally not vegan due to their coating. It’s also a good idea to go for organic if you can as you’ll be using the orange peel.
  • Measure in grams: With any baking, accuracy is key, and measuring in grams will always be more accurate.
  • Declump the sugar: Light muscovado sugar can sometimes “clump” together. Get your hands into the dry ingredients and work out any lumps of sugar as these can create spots when baking.
  • Use a parchment paper sling: A parchment sling covers the bottom and sides of the loaf tin, making it so much easier to lift out your vegan loaf cake once baked. King Arthur Baking shows detailed images on how to create a parchment sling.

Glaze

    Im so excited to taste this… it’s in the oven right now and smells delicious!
    Quick question, olive oil is in the ingredients but not listed in the steps. I just added it to the wet ingredients. Hope that’s where it went!
