Ingredients
Scale
- 1/4 cup all-purpose flour
- 1–3 tablespoons granulated sugar (adjust to taste)
- 1/4 teaspoon baking powder
- Pinch of salt (optional)
- 3 tablespoons milk
- 1 tablespoon butter, softened or melted
- 1/4 teaspoon vanilla extract
- 3 tablespoons fresh or frozen blueberries
Instructions
- In a large microwave-safe mug, whisk together the flour, sugar, baking powder, and optional salt until well combined.
- Add the milk, melted or softened butter, and vanilla extract. Stir until the batter is smooth and no dry flour remains.
- Gently fold in the blueberries, taking care not to crush them.
- Microwave on High for 1 minute.
- Check the cake. If the center is still wet, continue microwaving in 10-second intervals until the top is set. Total cooking time is usually 60–90 seconds, depending on your microwave.
- Let the mug cake cool for about 1 minute before serving.
- Enjoy as is, or top with powdered sugar, whipped cream, cinnamon sugar, or a scoop of vanilla ice cream.
Notes
- Start with 1 minute of microwave time and add extra time only if needed to avoid a rubbery texture.
- Fresh or frozen blueberries both work well.
- Use 1 tablespoon of sugar for a lightly sweet snack or up to 3 tablespoons for a richer dessert.
- Add 1/2 teaspoon of fresh lemon zest for a bright lemon-blueberry flavor.
- Make sure your mug is large enough to allow the cake to rise without overflowing.
- Serve warm with whipped cream, vanilla ice cream, or a drizzle of honey for an extra indulgent treat.
