Ingredients

Scale

Dry Ingredients

  • 4 tbsp All-purpose flour
  • 2 tbsp Unsweetened cocoa powder (Dutch-processed or regular)
  • 1/4 tsp Baking powder
  • 1 pinch Salt
  • 3 tbsp Granulated sugar
  • 1 tsp Espresso powder (Optional – enhances chocolate flavor)

Wet Ingredients

  • 3 tbsp Milk (Any kind: dairy or plant-based)
  • 2 tbsp Vegetable oil (Or melted butter)
  • 1/4 tsp Vanilla extract

Filling

  • 2 tbsp Chocolate chips (Or small piece of chocolate bar for molten center)

Instructions

  1. Prepare Equipment: Use a microwave-safe mug that can hold at least 12 ounces to avoid overflow during cooking.
  2. Mix Dry Ingredients: In the mug, combine 4 tablespoons all-purpose flour, 2 tablespoons unsweetened cocoa powder, 1/4 teaspoon baking powder, a pinch of salt, 3 tablespoons granulated sugar, and 1 teaspoon espresso powder if using. Stir thoroughly to evenly distribute all dry ingredients.
  3. Add Wet Ingredients: Add 3 tablespoons milk, 2 tablespoons vegetable oil, and 1/4 teaspoon vanilla extract to the dry mixture. Stir until you achieve a smooth batter without lumps.
  4. Add Chocolate Center: Gently press 2 tablespoons of chocolate chips or a small piece of chocolate bar into the center of the batter in the mug, ensuring it is slightly submerged to create the molten core.
  5. Cook in Microwave: Microwave the mug cake on high power for 70 to 90 seconds. Start with 70 seconds and check—cooking time may vary based on microwave wattage. The edges should be set while the center remains soft and gooey.
  6. Let Rest: Allow the cake to rest for about 1 minute to let it finish cooking from residual heat and to cool slightly for safe eating.
  7. Serve and Enjoy: Enjoy the molten lava mug cake directly from the mug, optionally topped with whipped cream, ice cream, or a dusting of powdered sugar for an added treat.

Notes

  • Microwave ovens vary; adjust cooking time accordingly to avoid overcooking or undercooking.
  • For a richer flavor, use melted butter instead of vegetable oil.
  • Espresso powder is optional but intensifies the chocolate taste without imparting a coffee flavor.
  • Make sure to leave room in the mug to prevent overflow while microwaving.
  • Consume immediately for the best molten lava effect.
