Ingredients

Servings
  • 1/4 cup butter
  • 1 ounce bittersweet chocolate¹ chopped
  • 1/4 cup granulated sugar
  • 2 large eggs
  • 2 tablespoons unsweetened cocoa powder
  • 1 teaspoon vanilla
  • 1/4 teaspoon salt
  • 1/4 cup all-purpose flour²
  • 1/2 teaspoon baking powder
  • 1 ounce semisweet or bittersweet chocolate in 4 pieces

Instructions

  1. Microwave butter and chocolate in a large microwave-safe bowl at 50% power³ until melted, about 1 minute.
  2. Stir in sugar, eggs, cocoa, vanilla, and salt.
  3. Add flour and baking powder, and whisk in.
  4. Divide the batter between 2 12-16 ounce⁴ microwave-safe mugs.
  5. Place mugs on microwave turntable.
  6. Microwave at 50% power for 45 seconds.
  7. Stir batter and microwave for another 45 seconds at 50% power.
  8. Press 2 pieces of chocolate into the center of each cake. No need to press down. They should sink in on their own.
  9. Microwave at 50% power for 60-90 seconds.
  10. Cake should pull away from the edge of the mug when done. 
  11. Let sit 2 minutes before serving.

Notes

  • Can substitute semisweet chocolate chocolate.
  • It's important to properly measure the flour. Either weigh the flour, or sift or stir it, lightly spoon into measuring cup, and then level. Too much flour will give you a dry or dense cake.
  • Microwaving at full powder will take less time. However, the chocolate will get absorbed into the cake, and you won't get a molten center. 
  • I like to use a 16-ounce mug because it allows more room for the cake to expand. A 12-ounce mug will work, but keep an eye on it to make sure it doesn't spill over as it cooks. 
  • Microwave wattages vary, and cooking times will vary according to the wattage. 
  • Nutrition values are estimates.
