Ultimate Chocolate Cupcake

\"WINNER WINNER WINNER! Search no more, you have created the Ultimate Chocolate Cupcake! These were hands-down the BEST chocolate cupcakes I have ever tasted, let alone baked myself. I am a sucker for cupcake bakeries and I honestly don’t believe any of the cupcakes I have paid $5 a piece for come even close to these.\"

"That was a quote from Amy Hendricks, one of the Chocolate Cupcake Recipe Cupcake Project Explorers (my team of 50 test bakers that helped perfect the chocolate cupcake recipe by baking seven rounds of cupcakes and providing feedback)."

Cupcake Project began in 2007 as Stefani Pollack's journey to master the cupcake (for the full back story, see her post about the nine month adventure preparing to bake cupcakes for her friends’ wedding). As the home to over 200 cupcake recipes, Cupcake Project has become an encyclopedia of what the cupcake can become. Stef’s cupcakes range from basic and brilliant (like the Ultimate Vanilla Cupcake) to downright bizarre (Cupcakewurst).
