Molten Lava Mug Cake is smooth, velvety and insanely good. This quite possibly could be my best Chocolate Mug Cake to date.

  • 2 tablespoons unsalted butter
  • 1/3 cup Ghirardelli® 60% Cacao Bittersweet Chocolate Baking Chips
  • 1 - 1 ⁄2 teaspoons Ghirardelli Unsweetened Cocoa Powder
  • 1 egg
  • 1 tablespoon white sugar
  • A pinch of salt
  • 1 teaspoon pure vanilla extract (optional)
  • 1 tablespoon Ghirardelli® 60% Cacao Bittersweet Chocolate Baking Chips
  • Toppings (optional): Vanilla Ice Cream Chocolate Shavings
  1. Place the butter and chocolate in a microwaveable mug (roughly 1 cup measurement). Microwave until melted, about 30-45 seconds.
  2. Mix in the cocoa powder, vanilla extract and salt, and stir until smooth.
  3. In another bowl, using an electric hand mixer or whisk, whip the egg and sugar until thick, roughly 3-4 minutes. It takes a little bit of elbow grease by hand.
  4. Pour the egg sugar mixture into your microwaveable mug containing your melted chocolate and butter and mix until smooth. Add in your chocolate chips on top and push them into the cake. This will give you your “lava” center. If you don’t want to cook them off straight away, then place them in the refrigerator for up to 24 hours.
  5. Microwave for 45-60 seconds. Take care not to overcook as it will dry out your lava cake. (Timing is based on my 1200W microwave so your timing might vary)
  6. Allow to cool for at least 5 minutes. Then scoop on your vanilla ice cream and finish with some chocolate shavings.
