  • ¼ cup all-purpose flour spoon and leveled
  • ¼ cup brown sugar packed
  • 2 tablespoons unsweetened cocoa powder
  • 1/4 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1/4 cup buttermilk
  • 2 tablespoons canola oil
  • 1 teaspoon vanilla extract
  • 2 tablespoons semi-sweet chocolate chunks
  • 1 tablespoon hot fudge topping


  • Mix flour, sugar, cocoa powder, baking soda, salt, buttermilk, oil, and vanilla in a large microwave-safe mug (should be able to hold at least 16 oz of liquid).
  • Stir in chocolate chunks.
  • Dollop hot fudge sauce in the center.
  • Cook in microwave 60 - 90 seconds and add more time as needed. The middle will still be gooey, but the outsides should have a cake-like texture.
  • Serve with ice cream.

This recipe was tested by 3 different people with 3 different microwaves and 60-75 seconds was perfect for all of us.
This recipe can be eaten by one person, but Trevor and I thought it was so rich, we actually enjoyed sharing one between the two of us with a couple scoops of ice cream!
