Description

This quick, single-serving blueberry mug cake offers a tender, moist sponge filled with juicy, fruit-infused pockets. Perfect for a quiet afternoon craving, this simple recipe comes together in minutes using standard pantry staples.


Ingredients

  • 4 tablespoons all-purpose flour
  • 1/4 teaspoon baking powder
  • 2 tablespoons granulated sugar
  • 3 tablespoons fat-free milk
  • 1 tablespoon vegetable oil
  • 1/4 teaspoon vanilla extract
  • 2 tablespoons fresh blueberries


Instructions

  1. Whisk dry ingredients. Add the all-purpose flour, baking powder, and granulated sugar into a microwave-safe mug and whisk together until combined.
  2. Combine with liquids. Pour the milk, oil, and vanilla extract into the mug and whisk until the batter is smooth and free of clumps.
  3. Fold in berries. Gently stir the fresh blueberries into the batter, ensuring they are evenly distributed throughout the mixture.
  4. Microwave the cake. Place the mug in the microwave and cook on high for sixty seconds, checking for a matte surface that springs back when touched.
  5. Check for doneness. Ensure the cake edges have pulled away from the mug and the center is set without any liquid batter remaining.
  6. Rest before serving. Carefully remove the mug from the microwave and allow it to sit for at least two to three minutes to let the crumb structure firm up.

Notes

  • Use a mug with at least a 12-ounce capacity to prevent the batter from overflowing during the rapid rise.
  • Tossing your fresh blueberries in a light coating of flour before folding them in helps prevent them from sinking to the bottom.
  • The resting time is essential; skip this step and the cake may collapse or have an unpleasantly wet, pudding-like texture.
  • Microwave power levels can vary, so start with 60 seconds and add 15-second intervals only if the center appears raw.
