Chefadora AI has the answer - timers, swaps, step-by-step help.
In a microwave-safe mug, melt the butter (about 30 seconds).
Stir in sugar, milk, and vanilla extract. Mix well.
Add flour, baking powder, and a pinch of salt. Stir until the batter is smooth and lump-free, scraping the sides of the mug.
Cook on medium-high power (about 800W) for 60 seconds. The cake should rise and look set on top but still be soft inside.
Let it rest for one minute before eating. Top with whipped cream, icing, or sprinkles if desired.
Add a handful of chocolate chips or sprinkles for a fun twist.
Swap the vanilla for almond or coconut extract for a new flavor.
Mix in a spoonful of peanut butter or Nutella for extra richness.
Serve warm with a dollop of whipped cream, a drizzle of caramel sauce, or a scoop of vanilla ice cream.
If your microwave is lower wattage, add 10–15 seconds to the cooking time.
Can I make this mug cake dairy-free?
Yes, you can use plant-based butter and milk, such as oat milk or almond milk, to make this recipe dairy-free.
What can I use instead of butter?
You can use 1 tablespoon of neutral oil as a substitute for butter for a lighter version.
Why is my mug cake rubbery?
If your mug cake is rubbery, it may have been overcooked. Try reducing the microwave time by 10 seconds.
Can I double the recipe?
Yes, you can double the ingredients to make two servings. Microwave each mug separately for 60–70 seconds.
How do I know when the mug cake is done?
The mug cake is done when the top looks set and springs back lightly when touched. If the center is undercooked, microwave in 10-second bursts until just set.
