Frequently Asked Questions
Why is my mug cake rubbery?
Overcooking is the #1 cause. Microwave for only 60-90 seconds — the cake should look slightly underdone in the center when you take it out. It continues cooking from residual heat. Also, don't overmix the batter; stir just until combined.
Can I make a mug cake without an egg?
Yes — this recipe is eggless! The butter and milk provide enough moisture and binding. If a recipe calls for an egg, substitute with 1 tablespoon of yogurt or applesauce.
What's the best mug for a mug cake?
Use a standard 12-16 oz ceramic mug (microwave-safe). Don't use narrow mugs — the batter may overflow. Fill the mug no more than halfway to allow room to rise.
