National Cupcake Week: Very Chocolatey Cupcakes with Marshmallow Buttercream Frosting

So, I finally got a chance to make some cupcakes this week. Wish I could have made some everyday for National Cupcake Week but I have been too busy! My friend from work, Becca, is moving to Australia and she had a leaving party last night. I wanted to make some cupcakes for her so I quickly whipped up 24 very chocolatey cupcakes with marshmallow buttercream frosting. I used the Hummingbird Bakery basic chocolate cupcake recipe but the batteries died on my scale as I was measuring the cocoa powder, so I have no idea how much cocoa I actually put in the cupcakes! It was more then the recipe called for, hence the new name very chocolatey cupcakes. I also tweaked the buttercream frosting recipe. The cupcake recipe can be found in the Hummingbird Bakery: Cake Days book, it is full of lovely and tasty recipes! Here is my recipe for the marshmallow buttercream frosting. Recipe Inspired by Hummingbird Bakery Ingredients: 500g icing sugar 160g unsalted butter 2Tbs whole milk 1Tbs marshmallow syrup 1/2tsp vanilla extract Steps: Put all ingredients into a large mixing bowl except the icing sugar.  Slowly add in the icing sugar in 3 batches, mix in very well!  Ready to frost 12 cupcakes.
