Cupcakes with a difference! Not only vegan, but these also have the most delicious bittersweet grapefruit flavour and are as moist and soft as you could ever imagine! Topped with grapefruit flavoured icing and little droplets of candied grapefruit peel, our Vegan Grapefruit Cupcakes may not be a hit with children, but will impress adults who love bitter citrus flavours!
Grapefruit isn’t necessarily the first ingredients that come to mind when thinking about cake flavours. However, limes, lemons and oranges are all widely used in baking, so grapefruit makes perfect sense to me! I love the slightly bitter notes that grapefruit adds to the otherwise sweet bake. We used both the juice and zest in the sponge to create an extra moist cupcake. And then we topped it with dairy-free buttercream icing (and some grapefruit peel too!)
There are many advantages to making buttercream icing with the dairy-free spread. First of all, most brands are so much easier to work with, given their soft texture. Secondly, it is lower in saturated fat, and therefore, in calories (not that you’re counting if you’re making these). Although real butter icing may hold the shape a bit better, there’s not that much flavour difference, especially if you’re flavouring your icing with something strong tasting.

To Make the Cupcakes:
Preheat the oven to 170°C Fan. Place 8-9 cupcake liners in a muffin tin or use the reusable silicone cupcake moulds. I love using silicone moulds, as the cupcakes slide out of them without leaving hardly any residue on them.
In a large mixing bowl, sift the flour, bicarbonate of soda, baking powder and salt. In a separate bowl, whisk sugar, soya milk, vegetable oil, grapefruit juice and zest. You can use olive oil if you wish, it adds another layer of bitter flavour (especially if you use extra virgin). I tried it with both oils, and my vote goes to vegetable oil, though.
Pour the wet ingredients into the flour mixture and stir just enough to combine. Fill the cupcake moulds/ liners about ¾ full. Then bake in the centre of the oven for 20-25 minutes. Allow the cupcakes to cool completely before icing them.
Make the Frosting:
In a large bowl, mix icing sugar, grapefruit juice and dairy-free spread. You can use a drop of food colouring too (I used a drop of red). Keep on mixing until almost all the icing sugar is incorporated and you have a thick paste. At first, you may think there’s not enough spread or too much icing sugar, but persevere and keep pressing the mixture with the back of the spoon against the walls of the bowl. It will eventually become a paste. And if it’s too thick, you can always add a drop of soya milk, but you cannot take it back. If you loosen your icing too much too early, it will not hold its shape when piped.
Place the icing in the fridge to firm up whilst the cupcakes are cooling.
Fill a piping bag with the frosting and pipe spirals on the cooled Vegan Grapefruit Cupcakes. Decorate with some candied grapefruit peel, if using. I use this recipe here.
Store in the fridge until you are ready to serve!
NOTE ON SUBSTITUTIONS: Don’t be tempted to substitute grapefruit juice for lime or lemon juice. Grapefruit has a lot less citric acid and more sugar! So if you substitute for the same amount of lemon or lime juice, you may need to adjust the sugar and raising agents to get enough rise.

Oh my god I am OBSESSED. Never did I think “grapefruit” when it came to cupcakes and this is just next-level. So good, so unique, and so wonderfully surprising. Can’t wait to make these again!

These look delicious. I have a friend who is vegan and I am always looking for something to make that she will enjoy as well as the non-vegans in attendance.
Ieva
I really hope she likes them! 🙂

I wouldve never thought of making cupcakes with grapefruit! It wasnt tart at all. The frosting was as delicious as the cupcake too!
Ieva
Thanks so much, Mirlene! Grapefruit is highly underrated when it comes to baking, in my opinion 😀
