Ingredients Method

Ingredients
  

  • 3 tablespoons all-purpose flour
  • 2 tablespoons granulated sugar
  • 1 tablespoon unsweetened cocoa powder
  • 1/4 teaspoon baking powder
  • 1 pinch salt
  • 3 tablespoons whole milk room temperature
  • 1 1/2 tablespoons vegetable oil or melted butter
  • 1/4 teaspoon vanilla extract
  • 1/4 teaspoon white vinegar
  • 3-4 drops red food coloring gel or liquid

Method
 

  1. In a 12-14 oz microwave-safe mug, whisk together the flour, sugar, cocoa powder, baking powder, and salt with a fork until no lumps remain.
  2. Add the milk, oil, vanilla extract, and white vinegar to the dry ingredients. Stir gently with a fork for 15-20 strokes until just combined and smooth.
  3. Add the red food coloring and stir 3-4 times until the batter is evenly colored. Avoid overmixing at this stage.
  4. Tap the mug gently on the counter 2-3 times to release any air bubbles from the batter.
  5. Microwave on high power for 60-70 seconds. The top should look just set with a slight sheen, not dry or cracked. If needed, microwave in additional 10-second intervals.
  6. Let the mug cake cool for 1-2 minutes before eating. The cake will firm up slightly as it cools and is easiest to eat directly from the mug with a spoon.
