Ingredients
Method
- In a 10-12 oz microwave-safe mug, stir together the flour, sugar, baking powder, and salt with a fork.
- Add the milk, oil or melted butter, and vanilla, stir until smooth, then gently fold in the blueberries.
- Microwave on high for 60-90 seconds until the top is set, cool 1 minute, top as you like, and serve warm.
Notes
If your microwave runs hot, check at 50 seconds and add time in small bursts. A tall mug prevents batter from climbing over the edge. This cake is best eaten right away while the blueberries are still warm and jammy.
