Double Chocolate Muffin Recipe

In general I like to stick with the classics, but I had a special plea for a chocolate muffin recipe, so I decided to put one up. These were inspired by Dorie Greenspan’s Chocolate-Chocolate Chunk Muffins from her excellent book, Baking: From My Home to Yours. The only difference is that I increased the sugar, since I felt they needed a little more sweetness (no offense, Dorie!). For a more austere muffin, something you would eat with a sweetened cup of coffee, subtract 1/3 cup of sugar.

3 ounces (6 tablespoons) butter
4 ounces bittersweet chocolate, chopped
10 ounces (2 cups) all-purpose flour
7 ounces (1 cup) sugar
1 ounce (1/3 cup) cocoa powder
1 tablespoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
10.5 ounces (1 1/4 cups) buttermilk
1 egg, room temperature
1 teaspoon vanilla extract
