Heat oven to 350°. Place a large sheet of nonstick aluminum foil into an 8 x 8-inch baking pan.
Place chocolate in a large microwave-safe bowl and microwave for 1 to 2 minutes, stirring halfway through, or until chocolate is melted. Whisk in cocoa powder and espresso powder; let cool 15 minutes.
Whisk together yogurt and eggs. Whisk sugar, vanilla and salt into yogurt mixture, then stir in chocolate mixture. Stir in flour until just blended.
Pour chocolate mixture into prepared pan and bake for about 55 minutes or until a toothpick inserted in the center tests clean. Remove foil from baking pan and set on a wire rack until completely cool.
