Ingredients

Scale

Dry Ingredients

  • ¼ cup all-purpose flour
  • 2 tablespoons granulated sugar
  • ¼ teaspoon baking powder
  • ⅛ teaspoon salt (pinch)

Wet Ingredients

  • 3 tablespoons milk (whole or plant-based)
  • 1 tablespoon vegetable oil
  • ¼ teaspoon vanilla extract

Fruit

  • 23 tablespoons fresh or frozen blueberries

Instructions

  1. Prepare the Mug: Select a microwave-safe mug (roughly 12 oz capacity) to ensure your cake has enough room to rise without overflowing.
  2. Mix Dry Ingredients: In the mug, combine ¼ cup all-purpose flour, 2 tablespoons granulated sugar, ¼ teaspoon baking powder, and a pinch (⅛ teaspoon) of salt. Stir well to evenly distribute the leavening and salt.
  3. Add Wet Ingredients: Pour in 3 tablespoons of milk, 1 tablespoon vegetable oil, and ¼ teaspoon vanilla extract to the dry ingredients. Stir thoroughly until you achieve a smooth, lump-free batter consistency.
  4. Fold in Blueberries: Gently fold 2-3 tablespoons of fresh or frozen blueberries into the batter, making sure they are evenly distributed throughout.
  5. Microwave the Cake: Place the mug in the microwave and cook on high power for about 90 seconds. Cooking time may vary depending on your microwave’s wattage; start checking around 70 seconds to prevent overcooking.
  6. Check Doneness: The cake should rise and appear set but still moist. Insert a toothpick or fork into the center; if it comes out clean or with moist crumbs, it’s ready.
  7. Cool and Serve: Allow the mug cake to cool for a minute or two to avoid burning your mouth, then enjoy straight from the mug or transfer onto a plate. Optionally, top with a dusting of powdered sugar or a scoop of ice cream for extra indulgence.

Notes

  • You can substitute vegetable oil with melted butter for a richer flavor.
  • Use any milk of choice, including plant-based alternatives like almond or soy milk.
  • If using frozen blueberries, do not thaw before adding to the batter to prevent bleeding color in the cake.
  • Microwave wattages vary; adjust cooking times accordingly to avoid overcooking or sogginess.
  • For a chocolate twist, add a tablespoon of cocoa powder to the dry ingredients.
