In my never ending quest to keep up with my sourdough starter, I found this recipe on the King Arthur Flour site. They made a cake with a frosting and a drizzle. I made cupcakes and used my quick, fudge frosting to ice them.
Sourdough Chocolate Cupcakes
1 cup “fed” sourdough starter
1 cup milk
2 cups all-purpose flour
1 1/2 cups sugar
1 cup vegetable oil
2 teaspoons vanilla extract
1 teaspoon salt
1 1/2 teaspoons baking soda
3/4 cup unsweetened cocoa (not Dutch process)
1 teaspoon espresso powder
2 large eggs
Feed your starter and remove one cup. Combine the fed starter, milk and flour in a large mixing bowl. Cover and let rest at room temperature for 2 to 3 hours. It will expand a little bit.
Preheat the oven to 350°F. Fill 2 muffin tins with cupcake liners.
In the bowl of a stand mixer, beat together the sugar, oil, vanilla, salt, baking soda, cocoa and espresso powder. Add the eggs one at a time, beating well after each addition. Gently combine the chocolate mixture with the starter-flour-milk mixture and beat gently until smooth. Pour the batter into the prepared liners.
Bake the cupcakes for 30 minutes, rotating pan midway through baking. Bake until a cake tester inserted into the center comes out clean. Remove from the oven and set it on a rack to cool for 5 minutes before removing from the pan. Once entirely cool, frost generously.
Makes 18 cupcakes.
Fudge Frosting
1 stick butter
1/4 cup cocoa
1/3 cup milk
2 cups powdered sugar
1 teaspoon vanilla
In a saucepan, combine butter, cocoa, and milk; bring to a boil. Add sugar and vanilla; beat well until smooth. Place in the refrigerator to cool before using. If frosting becomes too stiff, add 1 drop of milk at a time until it reaches the desired frosting consistency.
