Pumpkin Cupcakes with Marshmallow Frosting

I hate those recipes that ask you to use a bit of this and a bit of that. If I’m buying a tin of pumpkin puree I want to use the whole thing otherwise it will sit in my fridge for a week whilst I try and decide what else I can do with it. By the time I have come to a decision it is not fit for eating. Both the cupcakes and the frosting  here require you to buy stuff that you may not have in your store cupboard, pumpkin puree and marshmallow fluff, but don’t worry you will need to use the whole darn lot. Good for fridge space and good for your tummy.

I experimented with a few recipes to come up with the perfect pumpkin cupcake but then I realised it was all for naught as Martha Stewart has already cornered the market in the recipe below. I couldn’t better it and they are one of the tastiest, moistest cupcake sponges I have ever had. The frosting recipe makes a lot of marshmallowy goodness but if you are ruffling it onto the cupcakes like I did in the photos then that means you do need all of it.

I have loved coming up with Halloween inspired recipes this past week and I hope you have enjoyed the posts. Tomorrow I am making a last ditch attempt to get healthy before indulging in the upcoming excesses of the Christmas season with a month of gluten free recipes. I’m just telling you so you know you need to have a huge blow out tonight. Eat all the cupcakes! I’m gonna!

Marshmallow Buttercream

400g unsalted butter
500g icing sugar
2 tsp vanilla extract
2 x jars marshmallow fluff (about 400g in total)

  1. Whizz up the butter and the icing sugar on a high speed in the mixer for 5-10 mins until very light and fluffy.
  2. Add in the vanilla extract and mix well.
  3. Add the marshmallow fluff a spoon at a time whilst your mixer is on a slower speed until fully incorporated.


  1. When I first saw your recipe for marshmallow icing, I knew I was destined to use it. I absolutely love Marshmallow Fluff, I absolutely love cakes so it absolutely made sense that you put the two together!
    I slightly adapted mine to include strawberry jam, I wanted a subtle flavour and colour as the cupcakes that the icing would be adorning, were for a friends pink girly baby shower. The icing was such a lovely smooth consistency, a joy to pipe with and tasted perfect, not at all too sweet as I feared.
    Tomorrow I shall have my second attempt at using this recipe, in it’s natural state this time, to go atop a rainbow cake for my niece’s birthday party. I’m sure it will go down just as well as the strawberry version. Thank you!

    • Thank you so much for posting, I’m so pleased the recipe worked out well for you and it’s so lovely to hear feedback. I think marshmallow fluff is an absolute treat, I used it a couple of weeks ago mixed in with some chocolate when added to rice crispies for rice crispy squares which I must do a post on. Good luck with your cake for your niece’s birthday party – a rainbow cake sounds wonderful.
