Ingredients

Scale

Dry Ingredients

  • ¼ cup All-Purpose Flour
  • 2 tablespoons White Granulated Sugar
  • ¼ teaspoon Baking Powder
  • ⅛ teaspoon Pinch of Salt

Wet Ingredients

  • 3 tablespoons Milk (whole, 2%, skim, or plant-based)
  • 1 tablespoon Melted Butter or Vegetable Oil
  • ¼ teaspoon Vanilla Extract

Fruit

  • 23 tablespoons Fresh or Frozen Blueberries

Instructions

  1. Choose Your Mug: Select a 12-14 ounce microwave-safe ceramic mug with straight sides for even cooking. Avoid mugs with metallic paint or rims to prevent sparks.
  2. Combine the Dry Ingredients: Add the all-purpose flour, granulated sugar, baking powder, and salt into the mug. Use a fork to whisk thoroughly, ensuring the baking powder is evenly distributed for a uniform rise.
  3. Incorporate the Wet Ingredients: Pour in the milk, melted butter or vegetable oil, and vanilla extract directly into the mug on top of the dry ingredients.
  4. Mix Until Just Combined: Stir gently with a fork until no dry flour streaks remain. The batter should be slightly lumpy to avoid developing gluten that causes toughness.
  5. Fold in the Blueberries: Gently fold fresh or frozen blueberries into the batter. For better suspension, toss frozen blueberries with a little flour before folding in.
  6. Clean the Rim: Wipe any batter drips off the mug’s inside rim with a paper towel to prevent burning and for a cleaner presentation.
  7. Microwave to Perfection: Place the mug in the microwave center and cook on high for 70 to 90 seconds. Since microwave wattages vary, start with 70 seconds and adjust as needed.
  8. Check for Doneness: The muffin is done when the top is set and springs back lightly. Insert a toothpick to confirm—it should come out clean or with moist crumbs, not wet batter. Microwave in 10-second bursts if undercooked.
  9. Let It Rest: Remove the mug carefully and let the muffin rest for 1-2 minutes to complete cooking via residual steam and to allow flavors to meld before enjoying.

Notes

  • Using a mug with straight sides ensures the muffin cooks evenly in the microwave.
  • Do not overmix the batter to avoid a tough texture; slight lumps are desirable.
  • If using frozen blueberries, no thawing is necessary; toss them in flour to prevent sinking.
  • Microwave powers vary widely, so adjust cooking times accordingly to avoid under- or over-cooking.
  • Letting the muffin rest after microwaving is crucial for texture and flavor development.
