Ingredients

  • 2 tbsp butter
  • 1 oz dark chocolate
  • 3 tbsp milk
  • 2 tbsp sugar
  • 4 tbsp flour
  • 1 tbsp cocoa powder
  • 1/3 tsp baking powder
  • Pinch of salt
  • 1-2 chocolate truffles (e.g., Lindt dark chocolate) for the center

Instructions

  1. Step 1: In a 10-12oz microwave-safe mug, combine the butter and dark chocolate. Microwave in 15-second intervals, stirring between, until fully melted and smooth.
  2. Step 2: Add the milk and stir until blended.
  3. Step 3: Stir in the sugar until it dissolves.
  4. Step 4: Sift in the flour, cocoa powder, baking powder, and a pinch of salt. Stir well, scraping the edges and bottom so no dry flour remains.
  5. Step 5: Place 1-2 chocolate truffles in the center of the batter; no need to push them deeply.
  6. Step 6: Microwave on high for 60-70 seconds until the cake is set around the edges but soft and molten in the middle.
  7. Step 7: Optionally dust with powdered sugar before serving and enjoy immediately.

Tips & Variations

  • Use your favorite dark chocolate or chocolate truffles for a personalized touch.
  • Adjust cooking time slightly based on your microwave’s power to avoid overcooking.
  • Try adding a drop of vanilla extract or a pinch of cinnamon for extra flavor.
  • For a nutty twist, sprinkle chopped toasted nuts on top before microwaving.

Storage

This mug cake is best enjoyed fresh and warm. If you have leftovers, cover and refrigerate for up to 24 hours. Reheat briefly in the microwave (about 15-20 seconds) but note the molten center texture may be less pronounced after chilling.

FAQs

Can I use milk alternatives like almond or oat milk?

Yes, you can substitute regular milk with plant-based alternatives like almond, oat, or soy milk without affecting the texture much.

What if I don’t have chocolate truffles for the center?

If truffles aren’t available, use a small piece of chocolate or a spoonful of chocolate spread as the molten center instead.

  • 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

  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.

  • Eat straight from the mug while warm for best molten experience.
