7ouncesbittersweet chocolate(chopped ; I used 70% dark)
7ouncesunsalted butter(14 tablespoons)
1cupsugar
¼teaspoonsalt
4eggs
2 tablespoons + 1 teaspoonflour(substitute cocoa powder to make these gluten-free)
Instructions
Melt together chocolate and butter. (In the microwave, heat in 15 second bursts, stirring after each one, until mixture is smooth. On the stove, you can heat over a double boiler, or directly over medium heat in a heavy-bottomed pan, if you stir constantly and are very careful not to let the chocolate scorch.) Remove from heat, then whisk in the sugar. Let the pan cool for a few minutes (so you don't curdle your eggs). Add salt, then add eggs one at a time. Stir in flour.
Cover with plastic wrap and let batter rest for 30 minutes.
Grease a 12-cup muffin tin, or line with cupcake liners. Divide batter evenly among the cups; they will be between ½ and ⅔ full. Bake at 325F for 25 minutes, or until a toothpick inserted into the center comes out free of batter but with crumbs attached.
Let cool a few minutes before removing from the pan. The puffy tops will deflate as they cool.
Recipe Notes
You can substitute cocoa powder for flour to make these gluten-free, although I have not tried it.
