Ingredients

Scale

Wet Ingredients

  • 2 tbsp butter
  • 1 oz dark chocolate
  • 3 tbsp milk

Dry Ingredients

  • 2 tbsp sugar
  • 4 tbsp flour
  • 1 tbsp cocoa powder
  • 1/3 tsp baking powder
  • Pinch of salt

Filling

  • 12 chocolate truffles (e.g., Lindt dark chocolate)

Instructions

  1. Melt Butter and Chocolate: Place the butter and 1 oz dark chocolate in a 10-12 oz microwave-safe mug. Microwave in 15-second increments, stirring in between, until both are completely melted and combined into a smooth molten mixture.
  2. Add Milk: Stir in 3 tablespoons of milk thoroughly to blend with the melted chocolate mixture, creating a smooth batter base.
  3. Add Sugar: Mix in 2 tablespoons of sugar until fully incorporated and the batter is smooth.
  4. Combine Dry Ingredients: Sift together 4 tablespoons of flour, 1 tablespoon cocoa powder, 1/3 teaspoon baking powder, and a pinch of salt. Add these to the mug and stir well, making sure to scrape the edges and bottom to avoid any pockets of dry flour.
  5. Insert Chocolate Truffles: Place 1 to 2 chocolate truffles in the center of the batter in the mug. There’s no need to push them completely to the bottom; just nestle them in the middle.
  6. Microwave Cooking: Microwave the mug cake on high power for 60 to 70 seconds. The cake should be cooked on the outside with a molten center underneath the truffles.
  7. Garnish and Serve: Lightly dust the top of the mug cake with powdered sugar if desired, and enjoy immediately for the warm, gooey chocolate lava experience.

Notes

  • Cooking times may vary depending on your microwave wattage; adjust accordingly to avoid overcooking.
  • Use a microwave-safe mug that holds at least 10-12 oz to prevent overflow.
  • For a dairy-free version, substitute butter and milk with plant-based alternatives.
  • You can experiment with different chocolate types or fillings for variation.
  • Eat straight from the mug while warm for best molten experience.
