Description

Enjoy a rich, molten-centered chocolate cake in minutes with this simple, single-serving microwave recipe. It is the perfect cozy treat for quiet evenings, requiring only basic pantry staples and no preheating.


Ingredients

  • 4 tablespoons all-purpose flour
  • 2 tablespoons white sugar
  • 2 tablespoons unsweetened Dutch-process cocoa powder
  • 1/4 teaspoon baking powder
  • 1 pinch fine sea salt
  • 3 tablespoons whole milk
  • 1/4 teaspoon instant coffee granules
  • 1/4 teaspoon pure vanilla extract
  • 2 tablespoons neutral vegetable oil
  • 1 tablespoon dark chocolate chunks


Instructions

  1. Mix dry ingredients. In a 12-ounce ceramic mug, whisk together the flour, sugar, cocoa powder, baking powder, and salt until uniform.
  2. Prepare wet mixture. In a separate small container, dissolve the instant coffee granules into the milk, then stir in the vanilla extract and vegetable oil.
  3. Combine batter ingredients. Pour the wet mixture into the mug and stir with a fork using circular motions until just combined and glossy, being careful not to overmix.
  4. Add chocolate chunks. Scatter the dark chocolate chunks over the top and gently press them into the center of the batter with a fork.
  5. Microwave the cake. Cook on high power for 60 seconds, checking for a set crumb; adjust timing based on your microwave’s specific wattage.
  6. Cool and rest. Carefully remove the mug from the microwave and let it rest on a trivet for 3 minutes before serving to allow the center to finish setting.

Notes

  • Use a heavy-walled stoneware mug for the most even heat distribution during the cooking process.
  • Measure flour by spooning it into the measuring spoon to prevent packing, which can lead to a dry or rubbery texture.
  • Ensure the milk is at room temperature to prevent the vegetable oil from clumping upon contact.
  • Resting the cake for three minutes post-microwave is essential for achieving the perfect tender, melt-in-your-mouth crumb.
