These Gluten-Free Vegan Chocolate Cupcakes are moist, fluffy, and slathered in the most indulgent yet secretly healthy chocolate buttercream! They're easy to make, come together in one bowl, and are refined sugar free too. Perfect for birthdays and other occasions!

How to make the cupcakes
Scroll down to the bottom of the post for the full recipe.
- Mix together all the ingredients in a glass mixing bowl.
- Transfer the mixture into cupcake cases in a muffin/cupcake tin.
- Bake in the oven for around 15 minutes.
- Leave to cool before frosting.
How to make the chocolate frosting
My favourite part of these chocolate cupcakes, as with any cupcake, is the frosting! I used my Chocolate Sweet Potato Buttercream - it's so rich, creamy and velvety, yet is made with sweet potatoes.
Using sweet potatoes means this buttercream is inexpensive and secretly nutritious too. It might sound strange to use sweet potatoes for buttercream, but their naturally creamy texture and high sugar content make them a perfect contender, and once you add the cocoa powder, you honestly won't be able to guess what it's made of.
- Place all the ingredients in a food processor.
- Whizz until completely smooth.
- Make sure the cupcakes have cooled completely before applying the frosting.
- You can apply the frosting with a palette knife for frosting, a spatula, or a piping bag, depending on how fancy you want to be!
How long do these keep for?
These do taste best when fresh, but they keep covered in the fridge for up to a few days.
Substitutions you can make
- You can use any type of oil: coconut oil, olive oil or vegetable oil.
- You can use any type of plant-based milk: almond milk, rice milk, soy milk, cashew milk, oat milk etc.
- You can use any type of liquid sweetener: maple syrup, agave syrup, brown rice syrup etc.
- You can replace the vinegar with lemon juice.
- You can replace the ground almonds (almond meal) with ground walnuts.
- For a nut-free version: replace the ground almonds (almond meal) with ground sunflower seeds or use 30g (¼ cup) coconut flour instead of 150g (1 ¼ cup) ground almonds.
- You can use plain flour, wholemeal (whole wheat) flour or spelt flour instead of the gluten-free flour if you're not gluten-free.

- 2 tablespoons cocoa powder
- 1 teaspoon vanilla extract
- Pinch salt
- 3 tablespoons maple syrup (or sub any other sweetener)
- 1 teaspoon coconut oil
Instructions
For the cupcakes:
- Preheat oven to 180 degrees Celsius (350 degrees Fahrenheit).
- Place the coconut oil in a large bowl and melt over a saucepan of boiling water or in the microwave (skip this step if using any other oil).
- Once melted, add the milk to the same bowl along with the vinegar, maple syrup, vanilla, salt and ground almonds.
- Sift in the flour, baking powder, bicarbonate of soda and cocoa powder.
- Mix well, adding a tiny splash more milk if it’s looking too dry.
- Transfer mixture between 12 cupcake cases in a cupcake tin.
- Bake in oven for around 15 minutes until risen and an inserted skewer comes out clean.
- Once out of the oven, leave the cupcakes cool completely before applying the frosting.
For the buttercream:
- Cook sweet potatoes by boiling, steaming or roasting them until very soft and tender.
- Discard any skins, and add to a food processor or blender (or hand-held blender) along with all other ingredients.
- Whizz until completely smooth.
- Taste and adjust ingredients as necessary – add more maple syrup for sweetness, more salt for saltiness, more cocoa powder for chocolate flavour etc.
- Leave to cool before using to frost the cupcakes.
To frost and decorate the cupcakes:
- Once the cupcakes have cooled completely, use a knife or spatula to apply an even amount of frosting to each of the cupcakes.
- Best when fresh, but keeps well covered in the fridge for up to a few days.

Hi Rhian,
Can the almond powder be substituted by flaxseed meal.
I tried your orange cake. It was fantastic
Rhian Williams
Thank you so much, so glad you liked the orange cake! You can substitute the almond powder with ground sunflower seeds, ground walnuts or a fifth of the amount coconut flour. I'm not sure about flaxseed meal sorry, but would love to hear how you get on if you try it out!
