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.

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 ā 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.

Hi Rhian, your recipe says to use 1 cup (230ml) of almond milk - do you mean 250ml? And is this the same recipe as your chocolate sponge layer cake? I checked and saw that the ingredients for both recipes are the same, except for the chocolate sponge cake recipe, you said to use 250ml almond milk.
Rhian Williams
Hi Dora, thank you for your message! I'm so sorry for the confusion, yes they're the same recipe and this should be 250ml too, though to be honest it won't really make too much of a difference if you had used 230ml. But will change it to 250ml. So sorry about this and thank you so much for letting me know!

Hi Rhian,
These look delicious. Iām keen to try, just wondering if when substiting the almond flour for coconut , itās only 1/4? I noticed the almond meal is 1 1/4? Thanks !
Rhian Williams
Hi! Yes only 1/4 cup for coconut flour!

Hi Rhian, in the nutrition information do the calories include the frosting or is it just for the cupcake?
Rhian Williams

I made these. But didnt use almond flour just did all gluten free flour (all purpose). Ive been Trying out recipes before my kids bday. if your someone who isnt yet used to no sugar than these will not be great. Me and my kid thought you could barely taste the cocoa and hardly any sweetness. Really barely any flavor at all. I only made some at first and with the rest of the batch I then added more milk cuz even tho I had already added extra milk they needed alot more, plus added some sugar and more cocoa and they had much better flavor. I'm not sure how I would make the next batch with sugar instead of only maple syrup so I might have to try another recipe to make my daughter birthday cupcakes that wont disappoint on this new (health related) diet.
Thanks for sharing this recipe. Hopefully we are one step closer to perfect cupcake for my girl.
