Rest cake for 1 minute.
For frosting: Beat butter, powdered sugar, caramel, salt, and vanilla until thick. Add milk only if needed.
Spread or pipe frosting over the warm mug cake and serve.
Don’t overcook — the cake firms up as it rests.
Add flaky salt on top for extra caramel contrast.
Swirl frosting instead of spreading for bakery vibes.
Can I make this mug cake vegan?
Yes, you can use plant-based swaps like coconut oil or vegan butter for butter, and almond, oat, or soy milk for regular milk.
How do I avoid overcooking the mug cake?
Microwave for 75 seconds first and check. The cake firms up as it rests, so avoid microwaving for too long.
What can I use instead of caramel sauce?
You can use soft caramel candy as an alternative for the gooey center.
Can I make this gluten-free?
Yes, you can use gluten-free all-purpose flour as a substitute for regular flour.
How do I store the mug cake?
It's best eaten fresh, but you can cover it and let it rest at room temperature for up to 2 hours.
