Description

This single-serving mug cake delivers a perfectly steamed, tender crumb filled with fresh, jammy blueberries in just over a minute. By focusing on precise ratios and rapid microwave heat, you can enjoy a café-quality warm dessert without the need for an oven.


Ingredients

  • 30 grams all-purpose flour
  • 1/4 teaspoon baking powder
  • 2 1/2 teaspoons granulated sugar
  • 1 tablespoon fat-free milk
  • 1/2 tablespoon vegetable oil
  • 10 fresh blueberries
  • 1 drop vanilla extract


Instructions

  1. Prepare the workspace. Measure all ingredients accurately into small bowls and ensure liquids are at room temperature.
  2. Mix dry elements. Whisk the flour, baking powder, and sugar together in a microwave-safe mug until well combined.
  3. Combine wet ingredients. Add the milk, oil, and vanilla extract to the mug and whisk until the batter is smooth and glossy.
  4. Incorporate the fruit. Stir in the blueberries, ensuring they are gently pushed below the surface of the batter.
  5. Microwave the cake. Heat on high power for 60 seconds, adding an extra 10 to 15 seconds if the center appears wet or shiny.
  6. Allow for resting. Let the mug sit on a heatproof surface for three minutes to stabilize the structure before serving.

Notes

  • Use a wide, straight-sided mug to ensure the cake expands evenly and does not overflow.
  • Ensure you level your flour measurement precisely rather than scooping directly from the bag to maintain the correct crumb density.
  • Avoid over-mixing the batter to prevent the development of too much gluten, which can lead to a tough cake.
  • If using frozen blueberries, do not thaw them prior to mixing to prevent excess juices from discoloring the batter.
  • Adjust cooking times if using a microwave higher than 1000 watts to prevent the delicate cake from drying out.
