Pre-heat your oven to 140C Fan/160C/325F/Gas Mark 3, and line a cupcake tin with cupcake cases
For the cupcake sponge, mix together the butter and caster sugar, ideally using an electric mixer, for 5 minutes until smooth and fluffy
Add the eggs and Baileys, and mix well
Then gently whisk, or fold in, the self raising flour, cocoa powder and baking powder
Divide the mixture between the cupcake cases, and bake them for 25-30 minutes or until a thin skewer inserted in the centre of the cupcakes comes out clean. Put them on a rack to cool completely
To make the buttercream, mix the butter on it's own for 2-3 minutes, then add the icing sugar and the Baileys and mix until smooth. For best results use an electric hand whisk or a stand mixer with the paddle attachment
Pipe the buttercream onto each cupcake using a piping bag fitted with a nozzle. Or spread on with a spoon
Decorate with the Baileys truffles, paper straws and gold edible glitter
Store in an airtight container in a cool place, eat leftovers 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 decorated the cupcakes with Baileys Truffles, I usually get them from shops like B&M Bargains, Quality Save or Home Bargain. You can also get them from Amazon.
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.
