Pre-heat your oven to 160C Fan/180C/350F/Gas Mark 4, and line a cupcake tin with cupcake cases
To make the cupcakes, start by mixing the butter, light brown sugar and caster sugar together in a large bowl, ideally using an electric mixer for about 3 minutes
Add the eggs and milk, and whisk until fully incorporated
Add the self raising flour, cocoa powder, malt powder and baking powder, and whisk or fold in gently
Divide the mixture between the cupcakes cases, and bake them for 20-25 minutes or until a thin skewer or cocktail stick inserted in the centre of the cupcakes comes out clean. Put them on a cooling rack to cool completely
Use a cupcake corer or a knife to make a hole in the middle of each cupcake
Fill the holes with the Maltesers spread
To make the buttercream mix the butter on its own for a few minutes. Add the malt powder, icing sugar, milk and vanilla extract, and mix until smooth. For best results use a stand mixer with the paddle attachment. If the buttercream is too stiff then you can add a little more milk
Spread or pipe the buttercream on top of the cupcakes
Decorate with the Maltesers, Malteser buttons and the crushed Maltesers
Store in an airtight container in a cool place and eat within 3 days

Notes
Make sure all your ingredients (particularly the butter and eggs) are at room temperature before you start baking.
I used a baking spread for the cupcakes and unsalted butter for the buttercream.
I used a mix of sugars for the sponge. You can use all caster sugar or all light brown soft sugar if you prefer.
I used Horlicks instant malt powder for the cupcakes and buttercream.
The Maltesers spread is optional, if you can't get hold of it just make the cupcakes without it. I've seen it in Asda, Tesco, Sainsburys and also places like B&M and pound shops before. You can also buy it via the Amazon link below
The Malteser buttons for decoration are optional, you could use three Maltesers balls instead.
Although I provide cup measurements, I highly recommend weighing your ingredients out using digital kitchen scales*. It is the most accurate way to measure ingredients and will ensure the best results. Digital scales are very low cost and can be purchased for around £12 ($16.50) .
For teaspoon (tsp) and tablespoon (tbsp) measurements, please use measuring spoons* and not the type of spoons you eat with. Again this will ensure accuracy and provide the best results.
