Devil's Food Cupcakes with Chocolate Frosting : Bake-Along #83

It's time for some cupcakes at Bake-Along #83. Zoe has selected Devil's Food Cupcakes with Chocolate Frosting from Bon Appetit Desserts Cookbook, to bake together with Lena and myself, and anyone who wishes to bake-along with us.

Easy and simple to make, and yummy to eat! I made the full recipe and uses the standard muffin pan which yield 11 cupcakes. I've reduced both the sugars (brown and caster), and the cupcakes turned out to be just right for us, though it might not be sweet enough for some. With the chocolate frosting on the cupcakes, the sweetness balances out nicely.

As for the frosting, mine turned out a little thick. First thing is, I do not have any sour cream on hand, forgotten to buy! There's no more yoghurt, so I have used two tablespoons of milk instead. The chocolates, heavy cream and butter are stirred over a saucepan of simmering water until melted and smooth, remove from heat, then the vanilla extract, sour cream and icing sugar are stirred in until well blended. I have however did not read the instructions properly, and simply mixed everything to together. Ooops!!  Because I've used only 2 tablespoons of milk instead of 1/2 cup of sour cream, the frosting appears to be quite thick and I could use it immediately to spread over the cupcakes. And I've used only 2 tablespoons of icing sugar. As for the chocolate, I did not weigh them, simply break some pieces into the bowl. I was lazy to use the piping noozle (lazy to wash!), so I've just spread the frosting over the cupcakes using a small offset spatula.

I thought that my frosting was too fudgy and thick, but then both my kids love the frosting, there's even a request from my daughter to make the same frosting for her birthday cake. 

This cupcake is really nice. The cake is soft, airy, moist and chocolaty, made even yummier with the fudgy thick chocolate frosting.
