  • 1 tablespoon butter, melted
  • 2 tablespoons granulated sugar
  • ¼ cup (75g) chocolate syrup*
  • ¼ cup (31g) all-purpose flour
  • 2 tablespoons milk
  • ½ teaspoon baking powder
  • 1 pinch kosher salt


  • In a large, microwave-safe mug, melt the butter in the microwave. Add sugar and stir until well combined.
  • Add the remaining ingredients and mix until creamy, or no lumps are visible.
  • In one large mug (or two ramekins), microwave for 60-90 seconds, checking at 60 seconds. It is done when there are no more gooey spots. Remove from microwave and let rest for 60 seconds.
  • Serve with ice cream and more chocolate syrup.


You can use Hershey's Chocolate Syrup if you don't want to make your own! :)
