Best Chocolate Cupcake recipe?

So today I am testing a recipe I found online making the claim of being "the best chocolate cupcake recipe". For our school bazaar on saturday I'm doing ALOT of baking, so imagine my suprise when Honey came home tonight and sheepishly said "theres a cake sale at work tomorrow for mencap" and I replied "I'm already baking about 6 cakes, and 48 cupcakes for the bazaar!", however I decided that I did need to test out this new recipe I had found online, so have made some anyway!
Here's a few piccies (I apologise for my bad photography skills, I wish I could take better pictures!)

My piping skills need a little practice, but I'll be making these again on friday!

So for anyone who is interested, heres the (slightly quirky!) recipe for 20-30 cupcakes (depending on your tins!):

I apologise in advance, this is in cups, as its an american recipe, and I don't know the metric equivalents!

You just need to buy a set of cup measures, they're only a few pounds!

2 cups sugar
1 1/4 plain flour
3/4 cup  cocoa powder
1 1/2 tsp baking powder
1 1/2 tsp baking soda
1 tsp salt
2 eggs
1 cup milk
1/2 cup vegetable oil
2 tsp vanilla extract
1 cup boiling water
Heat oven to 180 degrees (350 farenheit). Combine the dry ingredients in a large bowl. Add eggs, milk, oil and vanilla; beat with electric whisk on medium speed for 2 minutes. Stir in boiling water. The batter will be thin, don’t worry about it. Pour into muffin tins, about  60% full. Bake at 180 degrees for about 22-25 minutes. Cool and then add your chosen icing. (Don't overfill the cases as they will rise, and just spill over!)

I decided to create my own buttercream icing, a bit of an experiment, but it tastes good! This is metric, as I made it up myself!
125g butter (room temp)
250g Chocolate spread (like nutella, but I just used Asda's)
175g icing sugar
First beat the butter and chocolate spread, then gradually add the icing sugar (too much too quick and you'll disappear in a white cloud!).Eh voila!

Here's the original post I found, with a much better picture.
