Have you ever imagined that you can make a sponge cake faster than you can brew tea?
This is not magic, but a reality that culinary gurus keep silent about. All you need is an ordinary mug and a microwave that has been gathering dust on the shelf for years.
Imagine: guests are already ringing the doorbell, and you don’t have dessert. Panic? Don’t. Mix four spoons of flour, three spoons of sugar, an egg, and two spoons of milk in a mug.

Shake with a fork as if you were making an omelette and microwave for three minutes. After 180 seconds, you'll have a fluffy sponge cake that's indistinguishable from the one your grandmother used to make.
The secret is that microwaves work many times faster than an oven - they heat the water in the dough, creating a steam effect that raises the mass like yeast.
Try adding a spoonful of cocoa to the mixture for a chocolate muffin. Or add a drop of vanilla extract for flavor.
And if you want to celebrate, stick marshmallow pieces into a hot sponge cake - they will melt and turn into a sticky sweet filling. By the way, in Japan this baking method became a trend ten years ago - there it is called "mug cake" and served with green tea.
The main thing is not to overcook the dessert, otherwise it will become rubbery. And yes, the mug should be large, otherwise the dough will "run away" and dirty the microwave.
It's proven: after this recipe, even children who hate cooking start experimenting in the kitchen.
