Chocolate Mint Cupcakes

Considering my love affair with all things chocolate mint, it’s not exactly a surprise that these cupcakes are a regular fixture within my baking arsenal. I’ve long been a fan of the mint Aero, with its crisp chocolate shell and delicate green-hued bubbly interior, but it took a longing stare into the vending machine at work for me to cotton on to the fact that it would be a rather chic decoration for a cupcake! 

These were first created as a birthday treat for a colleague, affectionately known as Monty – which has since earned them the name of Chocolate Monty Aero Cupcakes. A light-textured, dark chocolate sponge base, topped with a pale green mint buttercream swirl and a slice of mint Aero. Since I first made these, the Aero has been redesigned in a new shape bar, which in my opinion; isn’t a patch on the original in terms of cake decorating possibilities.  I’m sure that half an After Eight mint sliced diagonally on top would also look good, or even a simple chocolate button. 

I’m not usually one for ingredients snobbery, but my one piece of advice here is to use the best quality mint extract that you can afford. Although mint flavouring works, it’s just isn’t as fresh as an extract – you really do get what you pay for, and a better quality extract lasts longer as you don’t need to use as much. I’ve found the ones produced by Waitrose and Lakeland particularly good. You also need to use cocoa powder here rather than drinking chocolate to get a nice deep flavour and colour. 

These pretty but simple cupcakes have also been a big hit at bake sales in the office, so much so that I’ve been asked for the recipe on several occasions – so here it is…

  • Prep time: 40 minutes
  • Cook time: 20 minutes
  • Total time: 1 hour
  • Servings: Makes 12 cupcakes

Ingredients

For the sponge cakes

  • 175 g butter, softened
  • 175 g caster sugar
  • 3 eggs
  • 175 g self-raising flour
  • 2 tbsp cocoa powder, mixed to a paste with 2 tbsp hot water (or more if it's too thick to stir)
  • 1 tsp peppermint extract, optional, but good for extra mintyness

For the buttercream topping

  • 175 g butter, softened
  • 350 g icing sugar, sifted
  • 1 tbsp boiling water
  • 1 tsp peppermint extract, or more to taste
  • Few drops of green food colouring
  • Aero slices, chocolate buttons or After Eights for decoration

Method

To make the sponge cake

  • 1)

    Preheat the oven to 180°C / 350°F / Gas Mark 4 / Fan Oven 160°C and prepare a deep muffin tray with paper cases

  • 2)

    Cream the butter and sugar together until light and fluffy

  • 3)

    Add the eggs and a couple of spoonfuls of flour and beat until combined

  • 4)

    Add the remaining flour, the cocoa mix and the peppermint extract (if using) and beat until the mixture is thoroughly combined

  • 5)

    Spoon the mixture into the prepared tin until the paper cases are approximately half-filled (the mixture should make at least 12)

  • 6)

    Bake in the oven for approximately 20 minutes until the cakes are springy and an inserted skewer comes out clean. Leave to cool in the tin for 10 minutes before turning the cakes out on to a wire rack.

To make the buttercream topping and decorate the cakes

  • 1)

    Beat together the butter, icing sugar and hot water until pale and creamy

  • 2)

    Add the mint extract and a few drops of the green food colouring and beat until you have a nice pale green creamy icing

  • 3)

    Swirl the icing on top of the cooled cupcakes with the back of a spoon (or pipe if you’re feeling fancy) and decorate each cake with a slice of Aero, a chocolate button or half an After Eight.
