Mocha Cupcakes - cooking recipe

Ingredients

FOR THE CAKE
2 eggs
1/2 cup cold brewed coffee, plus
3 tablespoons brewed cold coffee
1/2 cup oil, plus
2 tablespoons oil
3 teaspoons cider vinegar
3 teaspoons vanilla extract
1 1/2 cups all-purpose flour
1 cup sugar
1 teaspoon baking soda
1/2 teaspoon salt
FOR THE FROSTING
6 1/2 tablespoons dark chocolate
1/3 cup butter, softened, plus
1 tablespoon butter, softened
2 1/4 cups confectioners' sugar
4 tablespoons brewed coffee
2 -3 tablespoons chopped dark chocolate
1 tablespoon cocoa powder

Preparation

In a large bowl, beat the eggs, coffee, oil, vinegar and vanilla until well blended. In a small bowl, combine the flour, sugar, baking soda and salt; gradually beat into coffee mixture until blended. Do not over mix (this will cause tough cupcakes).
Fill paper-lined muffin cups three-fourths full.(note: for cupcakes to all be the same size; use a 1/4-1/3 measuring cup to fill your cups). Bake at 350\u00b0 for 20-25 minutes or until a toothpick comes out clean and the cupcakes are a rather light gold, and mildly fluffed. Cool for about 10 minutes outside of the pan (to avoid residule cooking) before frosting *as below* .
For frosting, in a microwave or over a saucepan, melt chocolate and butter; stir until smooth. Transfer to a large bowl. Gradually beat in confectioners' sugar and coffee at a high rate until smooth and holding (also, if the frosting seems a tad runny; add a sprinkle more confectioners sugar/ coocoa powder). Pipe frosting onto cupcakes. Top with chopped chocolate bits.
Refridgerate for 6-7 days to keep fresh.
