Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
2 tablespoons butter, melted
2 1/2 tablespoons sugar
2 tablespoons milk
1/2 teaspoon vanilla extract
1/2 teaspoon baking powder
1/4 cup all-purpose flour, plus 1 tablespoon
7 to 8 blueberries
Directions
In a bowl, whisk together the melted butter, sugar, milk, and vanilla extract until smooth.
Add the baking powder and flour, then whisk until the batter is combined. Gently mix in the blueberries.
Pour the batter into two microwave-safe tea cups or one microwave-safe mug. Fill only halfway because the cake rises while cooking.
Microwave on high for 45 seconds to 1 minute. If the cake is not fully set, continue microwaving in 30-second intervals until done.
Serve warm, dusted with sugar and topped with extra blueberries if desired.

FAQs
Can I make this mug cake without eggs?

Can I use frozen blueberries?
Yes, frozen blueberries can be used. Add them directly to the batter without thawing.
Can I make this in one mug?
Yes, the batter can be cooked in one microwave-safe mug.
Why should I fill the mug only halfway?
The cake rises while cooking, so filling it halfway prevents overflow.
Can I use oil instead of butter?

Can I make it dairy-free?
Yes, use dairy-free milk and plant-based butter.
Why is my mug cake dry?
It may have been microwaved too long. Start with 45 seconds and add more time only if needed.
Can I add more blueberries?
Yes, but avoid adding too many because extra moisture can affect the texture.
Can I make this ahead of time?
It is best made fresh, since mug cakes taste softest right after cooking.
How do I know when it is done?
The top should look set and the cake should spring back lightly when touched.
