4 oz unsweetened chocolate, chopped
1 cup big chunks of chocolate bar
2 cups sugar
11/2 cup all-purpose flour
3/4 teaspoons baking soda
1/2 teaspoon kosher salt
1 cup hot brewed coffee
1/2 cup sour cream
1/2 cup vegetable oil
2 large eggs
1. Preheat the oven to 150C degrees.
2. Melt the chocolate on a double broiler, stir until smooth then remove from heat and set aside to cool.
3. Combine the dry ingredients: flour, sugar, baking soda, and salt. Whisk in the coffee, vegetable oil, and sour cream. Mix until well incorporated. Add the eggs, putting 1 egg at a time, stir in the melted chocolate, and mix well.
4. Scoop parts into a lined cupcake pan and put big chunks of chocolate into the cups. Place it into the preheated oven. Bake for about 10 to 15 minutes. Remove from the oven when a toothpick or skewer comes out clean. Let the batch cool completely before icing.
