Adapted from: Flour by Joanne Chang
Yield: 24 Cupcakes
This was originally a cake receipe that I found in ‘Flour’ by Joanne Chang. After one particularly bad day at a previous workplace I desperately needed a pick-me-up and went home and made the cake version… and yes perhaps ate it for dinner… my day was THAT bad!
Anyway after about the third slice I started eyeing the receipe as I wanted a bit more cake to buttercream ratio. Thinking about it I realised that it would make an excellent cupcake with a few minor tweaks. What you find here is a receipe I have made half a dozen times between that day and now.
Note: Due to the rum in the buttercream this isn’t really suitable for children; it’s decidedly grown up and just a little bit naughty!

METHOD – Cupcakes:
- Pre-heat oven to 180°C / 350°F
- Place the cupcake papers into the cupcake pans
- Place the unsalted butter and oil into the mixing bowl of the Mixmaster
- You will need the butter to be very soft, I find leaving it out overnight will get it to the correct consistency
- Using the paddle beater attachment, beat until the butter and oil is combined – Medium Speed
- Slowly add the sugar and vanilla extract and beat until the mixture appears light and fluffy and the sugar is dissolved – Medium Speed
- Scrap the bowl down to ensure that the mixture is fully incorporated
- Add the eggs one at a time, ensuring that you beat the mixture until everything is combined before adding the next egg – Medium Speed
- Scrap the bowl down to ensure that the mixture is fully incorporated
- In a medium bowl, sift the flour, baking powder, baking soda, spices and salt
- Add a third of the flour mixture to the mixing bowl and beat until just combined – Low Speed
- Add half of the buttermilk to the mixing bowl and beat until just combined – Low Speed
- Add a third of the flour mixture to the mixing bowl and beat until just combined – Low Speed
- Add the remaining half of the buttermilk to the mixing bowl and beat until just combined – Low Speed
- Add the remaining third of the flour mixture to the mixing bowl and beat until everything is incorporated but no more that 2mins – Low Speed
- Using the icecream scoop, fill the cupcake pans & papers until they are ⅔ full
- Bake each pan for 20 mins each
- Leave to cool slightly before moving to a wire rack to cool completely
METHOD – Buttercream:
- In a small heatproof bowl whisk together the sugar and egg whites until they are slightly frothy
- I use my Kitchenaid stainless steel mixing bowl – works perfectly
- Place the bowl over a pot of simmering water, do not let the bowl touch the water
- I find using the steamer on my pot set and sitting the bowl inside this avoids any issues during these steps
- Whisk the sugar and eggwhite mixture constantly for 8mins or until the mixture is very hot to touch and frothy – the sugar will completely dissolve during this process
- Remove bowl from heat and immediately use the Mixmaster with the whisk attachment to start whipping the mixture – Medium/High Speed
- Whip the mixture for 8mins or until the mixture is very thick, like meringue and it has started to cool
- Cut the unsalted butter into 1cm square chunks (½ inch)
- Slowly add the butter, one chunk at a time to the mixture, making sure that it has been completely incorporated before adding the next piece – Low Speed
- Don’t worry if the mixture starts looking like its separating, it will come back together as you continue to add the butter
- Once all the butter is incorporated, turn the mixer speed up to Medium and whisk for 3 minutes – Medium Speed
- Add the vanilla, salt and rum to the mixture and beat for another 2 minutes until everything is incorporated – Medium Speed
- Fill the buttercream into the pastry bag
- Using the 1M Wilton star tip, pipe a cupcake swirl onto each of the cupcakes then lightly grate the nutmeg over the cupcakes
The cupcakes will keep in an air tight container in a cool place for 2-3 days
MMM! Sounds awesome! Nutmeg and rum sounds like quite a combination!

I was intrigued by the combination which is why I tried it in the first place, the two flavours work exceptionally well together. Plus, your house will smell amazing whilst the cupcakes are baking =)
