Ingredients:

  • 4 tbsp all-purpose flour
  • 3 tbsp granulated sugar
  • 2 tbsp unsweetened cocoa powder
  • 1/4 tsp baking powder
  • 1 pinch salt
  • 3 tbsp whole milk
  • 2 tbsp neutral oil or melted butter
  • 1/2 tsp vanilla extract
  • 2 tbsp semi-sweet chocolate chips
  • 1 tsp water

Instructions:

  1. In a 12-ounce microwave-safe mug, whisk together the flour, sugar, cocoa powder, baking powder, and salt until no large clumps of cocoa remain.
  2. Add the milk, oil (or melted butter), and vanilla extract to the mug. Whisk vigorously until the batter is glossy and smooth, ensuring you scrape the bottom edges to incorporate all dry flour.
  3. Fold in 2 tbsp semi sweet chocolate chips.
  4. Drizzle 1 tsp water over the top of the batter. Do not stir this in; it creates a steam cap while cooking.
  5. Microwave on high for 1 minute 15 seconds until the top looks set but slightly shiny. Let the cake sit inside the microwave for 1 minute before removing. The aroma will intensify as the chocolate chips finish melting.
