Ingredients

Scale

Base Recipe

  • ¼ cup (35g) all-purpose flour
  • 2 tablespoons (25g) granulated sugar
  • ¼ teaspoon baking powder
  • Pinch of salt
  • 3 tablespoons (45ml) milk
  • 1 tablespoon (14g) unsalted butter, melted
  • ½ teaspoon vanilla extract
  • ⅓ cup (50g) fresh or frozen blueberries

Optional Add-Ins & Toppings

 

  • 1 tablespoon white chocolate chips
  • ½ teaspoon lemon zest
  • Extra blueberries for topping
  • Powdered sugar
  • Whipped cream
  • Vanilla ice cream
  • Maple syrup or honey drizzle

Instructions

  • Choose a large microwave-safe mug (12–16 oz capacity) to prevent overflow while cooking.
  • Add the flour, sugar, baking powder, and salt directly into the mug. Stir well with a fork until evenly combined.
  • Pour in the milk, melted butter, and vanilla extract. Mix until the batter becomes smooth and no dry streaks remain.
  • Gently fold in most of the blueberries, reserving a few for topping if desired.
  • Microwave on high power for 60–90 seconds. The cake is done when the top looks set but slightly moist in the center.
  • If needed, microwave in additional 10–15 second intervals until fully cooked. Avoid overcooking.
  • Let the mug cake cool for 1 minute before serving.
  • Top with powdered sugar, extra blueberries, whipped cream, or vanilla ice cream, then enjoy straight from the mug.

Notes

  • Frozen blueberries work perfectly and create a delicious jammy texture.
  • For a vegan version, use plant-based milk and coconut oil or vegan butter.
  • Add lemon zest for a bright lemon-blueberry flavor twist.
  • Microwave wattages vary, so begin checking at 60 seconds.
  • Avoid overmixing or overcooking to keep the cake soft and fluffy.
  • For a heartier texture, replace half the flour with oat flour.
  • Best enjoyed immediately after cooking for the freshest texture.
