Brain cupcakes

Experimental cupcakes for my husband to take to work for his birthday (he works with brains). They're caramel, with caramel icing. I was trying to copy Martha Stewards brain cupcakes, but don't quite have enough control over the piping bag yet!! Not a great example, but I've decided to post all my efforts so that further down the track I can look back and see how much I've improved!
