Ingredients

Scale
  • 2 tablespoons all-purpose flour
  • 1 tablespoon unsweetened cocoa powder
  • 2 tablespoons granulated sugar
  • 1/4 teaspoon baking powder
  • Pinch of salt
  • 1/8 teaspoon instant espresso powder (optional)
  • 2 tablespoons milk (dairy or plant-based)
  • 1 tablespoon unsalted butter, melted (or coconut oil)
  • 1/4 teaspoon pure vanilla extract
  • 1/2 ounce semi-sweet or dark chocolate chunk or square (about 1 tablespoon, for lava center)
  • Powdered sugar (optional, for topping)
  • Fresh berries (optional, for topping)
  • Whipped cream or vanilla ice cream (optional, for topping)

Instructions

  1. In a microwave-safe mug (10-12 oz), add flour, cocoa powder, sugar, baking powder, salt, and optional espresso powder. Stir with a fork until well combined and no lumps remain.
  2. Pour in milk, melted butter (or coconut oil), and vanilla extract. Mix until you have a smooth, thick batter. Scrape the sides so nothing is left unmixed. If batter is too thick, add a few drops more milk.
  3. Gently press a chunk of chocolate into the center of the batter, making sure it’s submerged but not touching the bottom of the mug.
  4. Microwave on high for 60-75 seconds. The cake will puff up and look set around the edges, but the middle should stay slightly soft. If the top looks wet, microwave for another 10-15 seconds. Do not overcook.
  5. Let the mug cake sit for 30-60 seconds before eating to allow the lava center to finish melting.
  6. Top with powdered sugar, berries, whipped cream, or vanilla ice cream as desired. Serve immediately.

Notes

Do not overmix the batter; stir just until combined for a tender cake. Microwave times may vary depending on wattage—start with less time and add more if needed. For gluten-free or vegan adaptations, use a 1:1 gluten-free flour blend, plant-based milk, coconut oil, and vegan chocolate. Serve hot for the best molten center. If mug cake overflows, use a larger mug next time.
